Yarn vs NPM

we preffer YARN. treba izbjegavati npm, jer yarn i npm imaju razlicite global foldere

Environment (Windows)

For Windows 10 the best way is to do it through the "Windows Subsystem for Linux" (WSL):

Environment (Mac)

Installing Node.JS

    • This package will install: • Node.js v12.13.1 to /usr/local/bin/node • npm v6.12.1 to /usr/local/bin/npm
  • IMPORTANT: due to issues with versioning ng/cli, angular, material, typescript, node, etc, we should currently stick to the latest v10 of node.js.
    • NOTE: there are node containers to help you to have various versions of node per different projects
  • after this, you can test if you have installed successfully node and containing npm, by running:
node -v
npm -v
  • tested versions: node: v6.11.2, npm: 3.10.10
  • curently testing versions: node: v10.16.0, npm: 6.9.0


If old, just download and reinstall newer version

However, cleaner and easier way is to install n package for managing node versions. We will use the n package in order to upgrade node:

npm cache clean -f
npm install -g n
# check available versions
n ls
# installing particular version (10.16.0), latest v10
n 10.16.0
# Under Linux it is installed as node, not nodejs
# under /usr/local/bin/node, not /usr/bin/nodejs

# it is possible to install it in a speciffic folder

Fixing npm-sudo-privileges

explained in


Yarn is a replacement for npm tools. It is faster, caching, reducing space, bandwith and time. We use it here, but you can use npm instead if you insist :)

# to be sure the `~/.bash_profile` file exists
touch  ~/.bash_profile
# install yarn
curl -o- -L | bash
# make `yarn` available in current terminal screen
source ~/.bash_profile

Installing brew

/usr/bin/ruby -e "$(curl -fsSL"
brew update

Installing mongodb server

MongoDB for OSX


brew update
brew tap mongodb/brew
brew install mongodb-community@4.2
sudo mkdir -p /data/db
mongod --version


if old:

brew upgrade mongodb


To have launchd start mongodb now and restart it at login: brew services start mongodb-community

Or, if you don't want/need a background service you can just run:

mongod --config /etc/mongod.conf

To start it in background (forked):

mongod --config /usr/local/etc/mongod.conf --fork


ps aux | grep -v grep | grep mongod
# or
sudo netstat -tulpn | grep ':27017'

installing Xcode

We install Xcode because we need the gcc compiler for native npm packages. It might be possible without it, but need to test. Also in that scenario some of the packages (like mongo driver), might be less efficient.

If you do not have XCode installed you should do

  • xcode-select --install

  • choose "install" to install Xcode Command Line Tools

  • or choose "Get XCode" to install Xcode (big)

  • after installing execute:

    • sudo xcode-select -s /Applications/

Verify that you’ve successfully installed Xcode Command Line Tools

  • xcode-select -p
  • Just to be certain, verify that gcc is installed
    • gcc --version

Environment (Ubuntu)

Installing Node.JS + NPM

# From
# This might change, better check the upper link
curl -sL | sudo -E bash -
sudo apt-get install -y nodejs

After installing Node.JS you will get instructions how to install Yarn:

# From
# This might change, better check the upper link
curl -sL | sudo apt-key add -
echo "deb stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt-get update && sudo apt-get install yarn

It is important to change npm to not require sudo for global packages:


# import the MongoDB public GPG Key from
wget -qO - | sudo apt-key add -
# Install gnupg and its required libraries
sudo apt-get install gnupg
# Once installed, retry importing the key
wget -qO - | sudo apt-key add -
# Create the list file /etc/apt/sources.list.d/mongodb-org-4.2.list for your version of Ubuntu
echo "deb [ arch=amd64 ] bionic/mongodb-org/4.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.2.list
# reload the local package database
sudo apt-get update
# install the latest stable version
sudo apt-get install -y mongodb-org

sudo mkdir -p /data/db
sudo touch /data/db/log

sudo mongod --dbpath /data/db --logpath /data/db/log
sudo mongod --dbpath /data/db --fork --logpath /data/db/log

# start
sudo service mongod start
sudo service mongod status


This is Typescript compiler

# typescript compiler should be global because we use it in angular, backend, etc
# later you run it as a `tsc` command

# we prefer installing it with yarn:
yarn global add typescript@2.7.2 (maximum for @angular we are using, but ...)
# currently we prefer this
yarn global add typescript@2.8.4 (minimum for @types/jasmine we are using)
yarn global add typescript@3.7.2 (minimum for the @types/chai we are using)

# another option would be installing it with npm
# latest
npm install -g typescript
# or maybe precise version, as ng requires v2.*
npm install -g typescript@2.7.2

SASS support

# this didn't work, ng serve was still complaining: Module build failed: Error: Cannot find module 'node-sass'
yarn global add node-sass
# this works
npm install -g node-sass


Angular NG CLI

Angular CLI is a main tool for developing angular applications

Links: (this is for the version 6:

yarn global add @angular/cli

we can also do

(even though not necessary): yarn global add gulp

Colabo.Space CLI

Colabo tools (CLI) is a main tool for maintaining Colabo.Space modular application consisting of colabo puzzles.


If you are planning to install development version of the Colabo.Space CLI please do, otherwise skip it:

yarn global add @colabo/cli
npm install -g @colabo/cli


after this procedure the yarn's global package.json should look like (with probably different versions)

  "dependencies": {
    "@angular/cli": "^8.3.20",
    "@colabo/cli": "^0.4.4",
    "node-sass": "^4.13.0",
    "typescript": "3.7.2"

Database and collections


MongoChef is a great client for Mongo db.

After installing it, you need to connect, and create new connection, it should be stright forward for the local server. Be sure that connection is with host: localhost, and port 27017.

Creating database and collections

  • Start MongoChef
  • Connect to localhost
  • create database KnAllEdge (File > Add Database ...).
  • download KnAllEdge DB samples
  • import them in Mongo
    • select database in MongoChef
    • import collections (tables in relational DBS are called collections in Mongod Schemaless DBS)
      • Database > Import Collections
      • Click on plus and navigate to your demo KnAllEdge collections
      • select all collections (each exported as a separate json file)
      • If you haven't installed KnAllEdge before and do not have important data then chose option Drop collection first if it allready exists
      • You can also select Validate JSON before import
      • Import
  • Now you can explore collections through the MongoChef interface

Starting for the first time

  • first we start mongo, by
sudo mongod
  • then we start the server, from "backend" folder by typing
npm start
  • at the end, we start the frontend from by typing
npm start

at "fronted" folder. It will start the browser. THen we press CTRL + F, back in the console. This will cause the first full build of the fronted. After its finished, we will probably have to kill the started browser tab, stop frontend from the console with CTRL + C and then restart it "npm start".

With this, our dev environment and CoLaboFramework should be working

Windows Condensed steps for Devs (OBSOLATED)

Default MongoDB installation should be good enough. The mongo database must be running before starting the server.

Installing mongodb server

MongoDB for Windows

Get info about windows:

wmic os get caption
wmic os get osarchitecture

Download the community version.

NOTE: These instructions assume that you have installed MongoDB to C:/mongodb folder. Therefore you need to choose custom installation and set the installation path to C:/mongodb.

Data folder

MongoDB requires a data directory to store all data. MongoDB’s default data directory path is /data/db. Create this folder using the following commands from a Command Prompt:

md c:/data/db


Navigate to c:/mongodb/bin/in command prompt and start the server:

cd c:\mongodb\bin\

When server starts, windows firewall system will ask you for granting access. Allow full access to the server.

Mongod should start on 27017 port.


Install backend

cd c:/data/development/Knalledge/
cd src/backend
npm install
cd modules/topiChat
npm install
cd ../topiChat-knalledge
npm install

Run backend server

cd c:/data/development/Knalledge/
cd src/backend
npm start

When server starts, windows firewall system will ask you for granting access. Allow full access to the server.

KnAllEdge backend server should start on 8888 port and its real-time support (topiChat) should start at 8060 port.

Testing the server

You can go to broweser and type the following command in order to check the connection and database integration:


You should expect something similar to (just and excerpt):

{"data":[{"_id":"5543c546645912db4fee9654","name":"Test Sasha","rootNodeId":"5543c545645912db4fee9653","type":"mcm_map","ideaId":0,"parentMapId":"Test","dataContent":{"mcm":{"authors":"Sasha"}},"__v":0,"updatedAt":"2015-05-01T18:26:14.352Z","createdAt":"2015-05-01T18:26:14.352Z","isPublic":true,"participants":[],"version":1,"activeVersion":1},{"_id":"5543c656645912db4fee9666","name":"SNAC","rootNodeId":"5543c656645912db4fee9665","type":"mcm_map","ideaId":0,"parentMapId":"SNAC","dataContent":{"mcm":{"authors":"Eunseo Choi"}},"__v":0,"updatedAt":"2015-05-01T18:30:46.402Z","createdAt":"2015-05-01T18:30:46.402Z","isPublic":true,"participants":[],"version":1.2,"activeVersion":1},{"_id":"5543cee34a653c345007c839","name":"mcm_changes","rootNodeId":"5543cee34a653c345007c838","type":"mcm_changes","ideaId":0,"parentMapId":"","dataContent":{"mcm":{"authors":"Sasha"}},"__v":0,"updatedAt":"2015-05-01T19:07:15.585Z","createdAt":"2015-05-01T19:07:15.583Z","isPublic":true,"participants":[],"version":1,"activeVersion":1},

and similarly, for:


Note: you will have prefix in the returned json: )]}', that helps to avoid browser JS attacks.

This is a positive signal that the backend is installed properly.

Default MongoDB installation should be good enough. The mongo database must be running before starting the server.


sudo service mongod stop
sudo service mongod start
sudo service mongod restart

After that you need to restart all services listening to it

restart knalledge-b

TODO: we need to make backend smart enough to detect new/restart/crash of the database

Running the backend

When you want to run the server you need to run specific package.json command: start. You do it by running:

npm start

Server will start, connect to default mongodb port and start listening for client connections on the announced port.


KnAllEdge - frontend class-diagram

Client is implemented at the moment as a ng1/2 hybrid (Angular1/Angular2). Angular

Debugging support

Debugging is handled with the support of the debugpp and debug libraries. Therefore in the browser console you need to enable debugging in order to see it:

This is how you would globally enable debugging:

localStorage.debug = '*';

or just for particular namespace (and all subspaces)

localStorage.debug = 'knalledge.collaboPluginsServices.*';

or just for the semantic-subspace (error in this case) of a for particular namespace:

localStorage.debug = 'knalledge.collaboPluginsServices.*.error';

Development deployment


Anything that should be served OUT of the dist/dev folder, should be mapped in the server config to be available: src/frontend/tools/utils/code_change_tools.ts

This is how we have enabled bower_components and images:

let routes:any = {
  '/bower_components': 'bower_components',
  '/app/images': 'app/images'

DefinitelyTyped conflicts

jQuery and Protractor (Seleinum) both use the same global variable: $. There fore TypeScript compiler complains:

⨯ Unable to compile TypeScript

typings/main/ambient/jquery/jquery.d.ts (3212,13): Subsequent variable declarations must have the same type.  Variable '$' must be of type 'cssSelectorHelper', but here has type 'JQueryStatic'. (2403)

At the moment there is no simple solution except remove it from some of the tools, etc. We did remove it manually:

Here are

Installing new machine (problems)

  • get backup of working machine
  • git clone ...
  • copy/overwrite folders/files

      • node_modules
      • tools/manual_typings
      • typings
      • typings.json
    • backend
      • it should work fine so just
        • cd backend
        • npm install

          • npm install
          • cd modules/topiChat-knalledge

        • node_modules
        • modules/topiChat/node_modules
        • modules/topiChat-knalledge/node_modules
  • now you can do symbolic linking

Upgrading MongoDB (OSX)

brew search mongodb

# 3.2 -> 3.4
brew install mongodb@3.4
# instead of 3.4.17 in 2 following rows, you might need to use appropriate version
sudo  /usr/local/Cellar/mongodb@3.4/3.4.17/bin/mongod
# and execute in the client the following commands:
    db.adminCommand( { getParameter: 1, featureCompatibilityVersion: 1 } )
    db.adminCommand( { setFeatureCompatibilityVersion: "3.4" } )
    db.adminCommand( { getParameter: 1, featureCompatibilityVersion: 1 } )

# 3.4 -> 3.6
brew install mongodb@3.6
sudo  /usr/local/Cellar/mongodb@3.6/3.6.8/bin/mongod
# and execute in the client the following commands:
    db.adminCommand( { getParameter: 1, featureCompatibilityVersion: 1 } )
    db.adminCommand( { setFeatureCompatibilityVersion: "3.6" } )
    db.adminCommand( { getParameter: 1, featureCompatibilityVersion: 1 } )

brew remove mongodb@3.4
brew remove mongodb@3.6

# 3.6 -> 4
brew install mongodb --with-openssl
sudo mongod
    db.adminCommand( { getParameter: 1, featureCompatibilityVersion: 1 } )
    db.adminCommand( { setFeatureCompatibilityVersion: "4.0" } )

XCode (gcc)

If you had the full XCode installed before and want to downgrade to Xcode Command Line Tools (smaller) then you should do

  • uninstall the XCode
  • set the CLT path xcode-select --switch /Library/Developer/CommandLineTools/

To check if gcc is properly working, you can create simple C++ file test.cpp at any convinient place:

#include <stdio.h>

int main(){
printf("Hello world!\n");

Then you can compile it with the gcc compiler:

gcc test.cpp

and run it:


You should get the message: Hello world!

npm WARN lifecycle The node binary used for scripts is /var/folders/kf/4b568dk10xdbh1hn4c08dpc00000gp/T/yarn--1562450253736-0.8092412955507404/node but npm is using /usr/local/bin/node itself. Use the `--scripts-prepend-node-path` option to include the path for the node binary npm was executed with.

You need to create a .npmrc file together with package.json with the scripts-prepend-node-path variable set to true:

scripts-prepend-node-path = true

we should not uninstall it


removing global packages (yarn & npm)

  • npm & yarn folders are different!
  • imas komande za spisak globalnih


  • yarn global list listing all global packages

    • @sir's case: ![image-20191207124342084](../../../../Library/Application Support/typora-user-images/image-20191207124342084.png)
  • but this dispaly is not consistent enough to user in yarn remove command. What we do we do:

    • yarn global dir that prints the output of the global installation folder that houses the global node_modules. By default that will be: ~/.config/yarn/global. (e.g. /Users/sir/.config/yarn/global)

    • we go to that folder and open its package.json and there we find package names.

      • for the above @sir's case, it contains

      • {
          "dependencies": {
            "@angular/cli": "^8.3.20",
            "gulp": "^4.0.2",
            "node-sass": "^4.13.0",
            "typescript": "3.7.2"
    • for each of the package names we do yarn global remove <package-name>

      • this will remove all the folders from the <global dir>/node_modules (even though there are many of them, they are probably there as dependencies of the few of those listed in the package.json, i.e in yarn global list)
  • for local packages (

    • In the case where I would want to remove all dependencies I would just rm -rf node_modules yarn.lock package.json and I would almost never want to do that.
  • Linked packages

  • Troubleshooting

    • maybe another package is dependent on the one you want to remove. I got a same situation when yarn global remove docsify,then I found docsify-cli was dependent on docsify, it worked when I do yarn global remove docsify-cli.


  • npm installs all its global modules to the same directory. we find it by npm root -g The exact location may vary, but typically it's /usr/local/lib/node_modules

    • @sir's listing:

      ![image-20191207235539130](../../../../Library/Application Support/typora-user-images/image-20191207235539130.png)


  • Kai Sternad's solution : The following command removes all global npm modules. Note: this does not work on Windows. For a working Windows version, see Ollie Bennett's Answer.

    npm ls -gp --depth=0 | awk -F/ '/node_modules/ && !/\/npm$/ {print $NF}' | xargs npm -g rm
    • but this command might break like in @sir's upper example with npm ERR! enoent ENOENT: no such file or directory, access '/usr/local/lib/node_modules/colabo-tools' (if it is linked to unexisting folder); so we can just do rm -rf colabo-tools and similar for each of the linked problematic ones

    • @sir's result of this set of commands: removed 956 packages in 27.737s

    • option 2 (Leonid Beschastny's solution)


      • Yet the upper command fails for the scoped packages, e.g. @angular. This is the command that handles them too: npm ls -gp --depth=0 | awk -F/ '/node_modules\/@/ {print $(NF-1)"/"$NF} /node_modules\/[^@]/ && !/\/npm$/ {print $NF}' | xargs npm -g rm

      • if it breaks for the non-existing folder, we also go inside its parent and remove that symlink (it's that in mosta cases)

      • yet, it also broke with this

        npm ERR! code EEXIST
        npm ERR! path /usr/local/bin/colabo
        npm ERR! Refusing to delete /usr/local/bin/colabo: ../lib/node_modules/@colabo/cli/dist/index.js symlink target is not controlled by npm /usr/local/lib/node_modules/@colabo/cli
        npm ERR! File exists: /usr/local/bin/colabo
        npm ERR! Move it away, and try again.
    • I tried Kai Sternad's solution but it seemed imperfect to me. There was a lot of special symbols left after the last awk from the deps tree itself.

    • So, I came up with my own modification of Kai Sternad's solution (with a little help from cashmere's idea):

    npm ls -gp --depth=0 | awk -F/node_modules/ '{print $2}' | grep -vE '^(npm|)$' | xargs -r npm -g rm
    • ​ @BrDaHa just checked it on my ubuntu with npm 1.4.21 and it worked fine. Though, it attempted to remove n node binary manager and node-gyp addon builder, but not npm. – Leonid Beschastny Nov 4 '14 at 18:42
  • you can see the list of all global npm-installed packages: npm list -g --depth=0

uninstall yarn

  • as (as can be seen in the lower INSTALL section) we installed it using CURL, this is the procedure
    • All it does is extracts the tarball to ~/.yarn so you can simply delete that directory. Maybe in the future we could have an uninstall script.
    • Oh yeah, it also adds ~/.yarn/bin to the PATH. Feel free to submit a pull request adding an uninstallation script if you like.
    • brew uninstall --force yarn cannot uninstall it in our case

uninstall npm & node

  • we can either use this manual approach

    • To completely uninstall node + npm is to do the following:

      1. go to /usr/local/lib and delete any node and node_modules
      2. go to /usr/local/include and delete any node and node_modules directory
        1. @sir: btw, this contains npm installation as I remember
      3. THIS DOESN'T WORK IN OUR CASE: if you installed with brew install node, then run brew uninstall node in your terminal
      4. check your Home directory for any local or lib or include folders, and delete any node or node_modules from there
        1. @sir, yet I (as others also suggested) have seen and deleted rm -rf /Users/[homedir]/.npm
      5. go to /usr/local/bin and delete any node executable
        1. @sir: Here I've also done:
          1. hmm. what? forgot to write it here :)

      You may also need to do:

      sudo rm -rf /opt/local/bin/node /opt/local/include/node /opt/local/lib/node_modules
      sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node.1 /usr/local/lib/dtrace/node.d
      • @sir in /usr/local/share/man/man1 I've also done:

        • rm -rf npm-* because there were a lot of symlinks whose name started with npm-

        • rm npm.1
          rm npx.1
          rm node.1
      • @sir in /usr/local/share/man/man5 I've also done:

        • rm -rf npm-*
          rm npmrc.5
          rm package*
      • @sir in /usr/local/share/man/man7 I've also done:

        • rm -rf npm-*
          rm removing-npm.7
          rm semver.7

      Additionally, NVM modifies the PATH variable in $HOME/.bashrc, which must be reverted manually.

  • OR we can start this script that deletes many things but then reinstalls and installs NVM

  • we installed node+Npm from the .pkg, but it's not in the Mac's Application folder

    • pa ok, pokrenuo si app installer ali je on instalirao samo u foldere, ne u Applications
    • @sir : ![image-20191208201749590](../../../../Library/Application Support/typora-user-images/image-20191208201749590.png)
    • @mprinc's folders node-npm-folders
  • Discussion

    • @mprinc: pa samo sa n instaliraj novi, ali mozes i deinstalirati stari, narano bolje je
    • i onda samo te obrisem? foldere? i tako deinstaliram? npm i node
      • [ December 6, 2019 23:48 ] Sasa Rudan: ja ne bih tako [ December 6, 2019 23:48 ] Sasa Rudan: pojuri nesto iskusnije, neko uputstvo

activities Order

  1. reinstaliraj xcode, instalira se nekako drugacije mislim, minimalna verija
  2. obrisi npm i yarn pakete
    1. obrisem globalne pakete pre nego deinstaliram npm i yarn?
  3. uninstall yarn
  4. uninstall npm i node
  5. OPTIONAL: drugo, instaliraj onaj n, za node.js versioning
    1. али за сада не
    2. tek na kraju ako ovo ne pomongne mozemo vidjeti sta dalje
  • ...


  • my node-sass (instalirao ga jarn dakle)



  • do at the end
    • (brew doctor)
    • brew cleanup

Troubleshoot during the next INSTALL phase


  • during the frontend: yarn it gets broken

  • it look's like it causes problems also to node-sass

  • we solved it with

    • using npm instead of yarn for node-sass install (in the later install phase)
    • deleting frontend/yarn.lock (including deleting frontend/node_modules)
    • yarn cache clean
    • fronted> yarn
    • we've repeated the same procedure for the frontend app yarn
  • this is the history of other attempts, just for some future need (not needed to be done now)

    • on discussion forums it's said that it gets fixed with the fsevents: ^ 1.2.9

    • we run in frontend: npm ls fsevents to check the versions installed

    • SRs-MacBook-Pro:frontend sir$ npm ls fsevents

    • I've changed yarn.lock

      • changed its dependencies to "^1.2.9"

      • and also changed fsevents entry from 1.2.4 to resolved ""

      • then I've deleted frontend/node_modules and reran yarn

      • during it I've got warnings

        warning @angular-devkit/build-angular > @angular-devkit/core > chokidar > fsevents@1.2.9: One of your dependencies needs to upgrade to fsevents v2: 1) Proper nodejs v10+ support 2) No more fetching binaries from AWS, smaller package size

      • but still the same errors

      • then I changed to resolved ""

      • and I've done yarn cache clean and rm -rf node_modules/

      • after that, no fsevent errors, but only

        warning Error running install script for optional dependency: "/Users/sir/Documents/data/development/ Command failed.
        Exit code: 1
