National Reporting Toolkit

NRT is an online system to help Governments collect, analyse and publish environmental information quickly and easily. It’s being built by the UNEP World Conservation Monitoring Centre, in partnership with the United Nations Environment Programme (UNEP) and the Abu Dhabi Global Environmental Data Initiative (AGEDI). You can find out more at nrt.io

Setup

Grab the dependencies by running the script for your platform in installers/. If you're doing this on a development machine, you probably want to review the installers first and remove any dependencies you already have installed (don't worry, they're short!)

• OS X: Uses homebrew to install the dependecies.

• Ubuntu: Uses apt-get

• Windows:

  • Ensure powershell is installed, then run install.bat as Admin
  • After the install has completed, setup the application with:

  cd server/ && npm run-script setup

Configuration

Your application needs configuration files for the environment it will be run in. View the configuration README for possible options.

Installing in windows as a service:

Install the application on windows as a service using NSSM. Configure NSSM as such:

Application:

• Path: C:\Path\To\node.exe
• Startup Directory: C:\Path\To\NRT\server
• Options: .\bin\server.js

I/O

Port all your IO to NRT\server\logs\service.log to be able to read STDOUT/ERR messages

Environment Variables

NODE_ENV=production
AUTH_TOKEN=changeme
PORT=80

Check your path

If you're intending to use this deployment for automated deploy, check that your environment variables are setup for the SYSTEM user which which will run the service. Otherwise, your deploy will fail with missing commands.

Running the application

Development

Start the server

In development, supervisor is used to handle exceptions:

cd server/ && npm start

Asset compilation

For more info, check out the asset README.

cd client && grunt && grunt watch

Logging in

In development, the users will be seeded on application boot. To login, pick a user from server/lib/users.json, e.g.

nrt@nrt.com
password

Seeding data

Data is seeded and updated from the /admin route. If you wish to update the indicators, you'll also need the Indicatorator running. If backup data is ok, just click 'Seed from backup'

Faking Indicator Data Backups

There is a JSON Generator script which generates data in the same format as the indicator data backup in server/lib/indicator_data.json. To generate fake data backups:

1. Grab the contents of the file and enter it into the JSON generator
2. Save the generated output to the backup file at server/lib/indicator_data.json
3. Seed from backup by visiting /admin and clicking 'seed from backup'

Production

Start the server

Windows

• cd server
• npm run-script win-production

Unix

• cd server/ && npm run-script production

Asset compilation

For more info, check out the asset README.

cd client && grunt

Authentication and logging in

In production, no users are seeded and have to be created manually. However, you can use an LDAP server for authentication once it has been configured. Note that for EAD LDAP use, you must be within the EAD VPN.

LDAP

NRT can connect to a LDAP to authenticate and create users. LDAP is configured by the file server/config/ldap.json, and an example can be found in server/config/ldap.json.example. See the deployment secrets document for the production details you need.

LDAP is a optional feature which can be disabled in the application config: https://github.com/unepwcmc/NRT/tree/master/server/config#example

Automatic deployments

Once the application has been setup manually for the first time on a server, you can automatically deploy new code pushed to the deploy branch on Github.

Only one step of setup is required:

1. Add a WebHook service hook that points at your server's deploy route (http://youdomain.com/deploy).

Github will notify the server of any changes, and the application should automatically pull the new code and update the server's local repository. Make sure you are running your application with forever or it will not restart after a deploy.

Application structure

Server

app.coffee

Application entry point. Includes required modules and starts the server

route_bindings.coffee

Binds the server paths (e.g. '/indicators/') to the controllers in the controllers folder

controllers/

Contains the 'actions' in the application, grouped into modules by their responsibility. These are mapped to paths by route_bindings.coffee

models/

Mongoose schemas, and model instantiation.

Client

A BackboneDiorama application

Development

Tests

Server

In the server/test/ folder (unsurprisingly). We're using mocha with the qunit interface and using the chai assertion syntax.

Run them with

npm test

Using Q for deferreds in tests

Q.js is used through-out the application to prevent callback pyramids. One thing to note when using it, particularly in tests, is that you must specify a fail callback as well as success for every deferred, or your application will silently fail. In tests, you can usually just handle do this by passing mocha's done function to fail, e.g:

test('somePromiseFunction', (done) ->
  somePromiseFunction.then(->
    # some assertions
    done()
  ).fail(done) # This will call done with an error as first argument, which triggers mocha's error state
)

Client

Running 'em

Ensure you've run grunt to compile the tests, and fire up the app server:

npm start

Then visit http://localhost:3000/tests

Writing 'em

The tests are written in mocha, using the qunit syntax with chai for asserts. Write tests in Coffeescript in the client/test/src/ folder and compile them with grunt.

Debugging

Server

You can use node-inspector to debug the server components.

• Install and run node-inspector
  • npm install -g node-inspector
  • node-inspector &
• Run the server with npm run-script debug
• Navigate to the debugger in your browser.

You can now check out console logs and use breakpoints (in your code with debugger and in the inspector itself) inside your browser.

Workflow

Tabs (nope)

No tabs please, 2 spaces in all languages (HTML, CSS, Coffeescript...)

Line-length

80 characters

Commit workflow

Work on feature branches, commit often with small commits with only one change to the code. When you're ready to merge your code into the master branch, submit a pull request and have someone else review it.

Commenting your code

Writing small (<10 lines), well named functions is preferable to comments, but obviously comment when your code isn't intuitive.

Documentation

New developers will expected to be able to get the application up and running on their development machines purely by reading the README. Doing anything in the app workflow which isn't intuitive? Make sure it's in here.

User Management

A simple user management system is in place, with a CRUD (minus the U) API. A secret token is required to authenticate yourself and manage users. This token is set by an environment variable, AUTH_TOKEN.

For example, run your app as so:

AUTH_TOKEN=my-very-secret-token npm start

Listing all users

curl http://<domain>/api/users\?token\=my-very-secret-token

Adding a user

curl -X POST -d "email=hats@boats.com&password=password" http://<domain>/api/users\?token\=my-very-secret-token

Deleting a user

curl -i -X DELETE http://<domain>/api/users/<id>\?token\=my-very-secret-token

Production

WCMC team should already have access to this document
