Welcome to Blink 👋

Modern, lightweight, planet-scale link shortener for teams 🎉

Easy to setup, connect with your org's SSO, hook up analytics, and extend!

See the documentation for more information about the project itself (including screenshots)

Development

Prerequisites

You need the following components to develop and run Blink locally:

mkcert
docker & docker-compose (note that on Linux, docker & docker-compose are two separate deps)
an x86-based machine (unfortunately, Keycloak - even in its latest version - does not work with ARM-based devices)

Before you start

Run make cert to generate the SSL certs required for HTTPS local development
Run make up to stand up the containers

And once you're done with development, you can run make down to shut down and cleanup all the containers that spun up.

NOTE: that you actually do not have to run the cleanup every time you npm start; you can shut down the npm start server/frontend combo and re-boot it as many times as you'd like without needing to make up every time - the migrations and the build process will run fine even with existing data(!)

Starting Blink

Run make dev to stand up the development environment (i.e. it will run the actual container in which Blink will be run in "dev mode", which is fancy term for NODE_ENV=development). Then, run npm start to run Blink, which consists of a backend express server and a frontend react "live-loader". You can access the app at https://localhost/app! Both the frontend and the backend will live-reload as you make changes. You can login as the user specified at the end of config/keycloak.json (username: user, password: Password1).

Behind the scenes, the frontend (a create-react-app app) is running at http://localhost:4000/app and is being reverse proxied from https://localhost/app, and everything else in https://localhost gets proxied to the backend at http://localhost:3000. Yes, there are two processes running in the container pretending to be one "site", but this kind of routing (thanks Traefik!) allows us to not have horrible routing issues (stemming from the fact that even though they're both http://localhost, the different port means they're effectively two different sites and leads to a whole host of routing, CORS, and other integration issues), and allows testing of features that are only available for HTTPS in order to simulate real-world usage as much as possible.

Troubleshooting

If you can't reach any service or if you suspect the routing is messed up, first check https://traefik.localhost to make sure that everything is configured correctly.

Note that for performance/security reasons, the app container is built end-to-end with alpine-based images, so you won't have access to anything fancy like, say, bash.

Run tests

make test COMMAND='npm test'

# or, for interactive testing:
make test
$ npm run test:watch

Deployment with Docker Compose

Under the /Deploy/Docker-Compose/ directory in this repo is a base docker-compose.yml and .env files that you can use to deploy this with no building necessary. Just ensure the database details are entered correctly (strongly advise using a different password for the database than is currently specified) and that you've added relevent OIDC/OAUTH/SESSION config to the .env file and you should be good to go.

Simply download both files, and run:

docker compose up -d
