Example repo showing a ReasonReact project with hooks + tests, using BuckleScript package-specs.module: "es6" configuration.

Run Project

yarn
yarn start
# in another tab
yarn webpack

After you see the webpack compilation succeed (the yarn webpack step), open up build/index.html (no server needed!). Then modify whichever .re file in src and refresh the page to see the changes.

Run Project with Server

To run with the webpack development server run yarn server and view in the browser at http://localhost:8000. Running in this environment provides hot reloading and support for routing; just edit and save the file and the browser will automatically refresh.

Note that any hot reload on a route will fall back to the root (/), so ReasonReact.Router.dangerouslyGetInitialUrl will likely be needed alongside the ReasonReact.Router.watchUrl logic to handle routing correctly on hot reload refreshes or simply opening the app at a URL that is not the root.

To use a port other than 8000 set the PORT environment variable (PORT=8080 yarn server).

Build for Production

yarn clean
yarn build
yarn webpack:production

This will replace the development artifact build/Index.js for an optimized version as well as copy src/index.html into build/. You can then deploy the contents of the build directory (index.html and Index.js).

If you make use of routing (via ReasonReact.Router or similar logic) ensure that server-side routing handles your routes or that 404's are directed back to index.html (which is how the dev server is set up).
