You can use a fully functional local version to develop and test both frontend and backend. It requires at least 2GB RAM or swap enabled.
To bring it up run:
# if you mainly work on backend
cp compose-dev-backend.yml compose-private.yml
# if you mainly work on frontend
cp compose-dev-frontend.yml compose-private.yml
# now, edit / debug `compose-private.yml` to your heart's content
# build and run
docker-compose -f compose-private.yml build
docker-compose -f compose-private.yml up
It starts Remark42 on
127.0.0.1:8080 and adds local OAuth2 provider "Dev". To access the UI demo page go to
127.0.0.1:8080/web. By default, you would be logged in as
dev_user which is defined as admin. You can tweak any of supported parameters in corresponded yml file.
Backend Docker Compose config by default skips running frontend related tests. Frontend Docker Compose config by default skips running backend related tests and sets
NODE_ENV=development for frontend build.
To run backend locally (development mode, without Docker) you have to have the latest stable
go toolchain installed.
To run backend -
cd backend; go run app/main.go server --dbg --secret=12345 --url=http://127.0.0.1:8080 --admin-passwd=password --site=remark. It stars backend service with embedded bolt store on port
8080 with basic auth, allowing to authenticate and run requests directly, like this:
Frontend development guide can be found here.
You should have at least 2GB RAM or swap enabled for building.
- install Node.js 12.11 or higher
- install NPM 6.13.4
npm run buildthere
- result files will be saved in
npm install will set up pre-commit hooks into your git repository. It used to reformat your frontend code using
prettier and lint with
stylelint before every commit.
For local development mode with Hot Reloading use
npm start instead of
npm run build. In this case,
webpack will serve files using
localhost:9000. By visiting
127.0.0.1:9000/web you will get a page with the main comments widget communicating with a demo server backend running on
https://demo.remark42.com. But you will not be able to log in with any OAuth providers due to security reasons.
You can attach to the locally running backend by providing
REMARK_URL environment variable.
npx cross-env REMARK_URL=http://127.0.0.1:8080 npm start
Note: If you want to redefine env variables such as
PORT on your local instance you can add
.env file to
./frontend folder and rewrite variables as you wish. For such functional, we use
The best way to start a local developer environment:
cp compose-dev-frontend.yml compose-private-frontend.yml
docker-compose -f compose-private-frontend.yml up --build
npm run dev
