Catalyst | Vue WebApp

This is the repo for Not-Equal Catalyst's frontend webapp. It is a Vue.js project written in JavaScript, pug and sass and deployed through Docker where it is served using express and vue-ssr.

What is Not-Equal Catalyst?

Table of Contents



To develop on this repo you will need to have Docker and node.js installed on your dev machine and have an understanding of them. This guide assumes you have the repo checked out and are on macOS, but equivalent commands are available. You will also need a Trello account which is used to pull the data from.

You'll only need to follow this setup once for your dev machine.

# Install dependancies
npm install

# Setup your client environment
cp .env.example .env.local

# Follow these instructions to get your Trello credentials

# Setup your server environment
cp .env.server.example .env.server.local

Regular use

These are the commands you'll regularly run to develop the API, in no particular order.

# Start up a redis instance, fetch projects and serve them with the api
# -> Run this in a new terminal tab
# -> Stop this with a Ctrl+C
# -> See `docker-compose.yml` for how it works
docker-compuse up

# Compile and run the vue-cli-service's server
# -> Internally uses webpack to transpile assets to html, css & js
# -> Stop this with a Ctrl+C
# -> Only runs the client, no ssr yet
npm run serve
open http://localhost:8080

Irregular use

These are commands you might need to run but probably won't, also in no particular order.

# Generate the table of contents for this readme
# -> It'll replace content between the toc-head and toc-tail HTML comments
npm run gen-readme-toc

# Manually lint code with TypeScript's `tsc`
npm run lint

# Manually format code
# -> This repo is setup to automatically format code on git-push
npm run prettier

# Manually build all assets (html, css, js & images)
# -> Runs both the other build commands together
# -> Writes to dist/
npm run build

# Manually build the assets for the client
npm run build:client

# Manually build the assets for the server (creates a vue-ssr-server-bundle-json)
npm run build:client

# Run the ssr server
# -> Requires .env.server.local to be setup
# -> Stop this with a Ctrl+C
# -> Just runs the server, no file watching or restarting
node server/index.js

Code Structure

Folder Contents
dist Where the html, css, js & img assets are built to
node_modules Where npm's modules get installed into
public Unmodified assets, served directly to the client
server The source code for the vue-ssr express server
src The source code for the web app
src/assets Image assets that are built into the app
src/components Reusable Vue components
src/data Static information for the web app
src/sass Custom styles written in sass
src/views The app's views, components which are routed to

Webpack build

This repo uses vue-cli-service to handle most webpack configuration, including babel, post-css and processing .vue components. There are some tweaks to the defaults, these can be found in vue.config.js and are detailed below.

  • shared.sass is automatically imported for each Vue component's <style> tags (with variables and mixins)
  • process.env.VUE_APP_VERSION is set to the package.json version
  • It adds vue-svg-loader
  • It sets up the required things for vue-ssr

Code formatting

This repo uses Prettier to automatically format code to a consistent standard. This works using the husky and lint-staged packages to automatically format code whenever you commit code. This means that code that is pushed to the repo is always formatted to a consistent standard.

You can manually run the formatter with npm run prettier if you want.

Prettier is slightly configured in .prettierrc.yml and also ignores files using .prettierignore.


Building the image

This repo uses a GitLab CI to build a Docker image when you push a git tag. This is designed to be used with the npm version command so all docker images are semantically versioned. The :latest docker tag is not used.

This job runs using the .gitlab-ci.yml file which runs a docker build using the Dockerfile and only runs when you push a tag.

It pushes these docker images to the GitLab registry of the repo. A slight nuance is that it will replace a preceding v in tag names, formatting v1.0.0 to 1.0.0.

# Deploy a new version of the CLI
npm version # major | minor | patch
git push --tags

Using the image

With this docker image you can easily deploy and run the vue-ssr server using docker-compose. The express server runs on 8080 inside the container, so you'll need to map that for external traffic.

Here's an example with docker-compose:

For more info see catalyst-example-stack

version: '3'

      - 8080:8080
      REDIS_URL: redis://your_redis_url

Environment variables

There are some required environment variables, shown below.

Variable Description
REDIS_URL The redis connection uri
PUBLIC_URL Where the app is, used for generating opengraph meta
API_URL Where the api is, passed into the webapp through vuex

There are some optional variables too:

Variable Description
APP_NAME Set the app's name, used in opengraph
APP_INFO Set the app's description, used in opengraph
