MobX State Router

MobX-powered router for React apps.

Features

• State is decoupled from the UI. UI is simply a function of the state.
• UI is no longer responsible for fetching data. Data is now fetched during state transitions using router hooks.
• The router can override routing requests based on the application state. For example, it can redirect to the Sign In page if the user is not logged in.
• Supports
  • 404 (Not Found) errors
  • Server-Side Rendering

Contributors

Make sure all your commit messages conform to the Angular Commit Message Conventions.

To simplify this process, we have included Commitizen as a dependency of this project. Always execute the following command sequence to commit your changes. It will prompt you to fill out any required commit fields interactively.

git add --all
yarn cz-commit # interactive conventional commit
git push

Testing local builds

To test local builds with examples in the examples folder, follow the steps listed below:

• Build the package

yarn build:local  # creates a dist folder

• Create a tarball from the package

npm pack  # packages src and dist into a tarball with name [package-name]-[version].tgz

• Go to an example in the examples directory and add the tarball as a dependency

cd examples/mobx-shop
yarn add ../../[package-name]-[version].tgz

• Run the example

yarn start

Release to NPM

• Change the version number in package.json. Use semver. For pre-release versions add a suffix & build number, e.g 5.0.0-beta.1.

• Commit and push (see above)

• Build the package

yarn build:local

• Release to npm

npm publish             # for normal release (adds `latest` tag)
npm publish --tag next  # for pre-release (adds `next` tag)

• Tag the release and push the tag to remote

mobx-state-router is based on ideas from several Open Source projects. I am grateful to the developers of these projects for their contributions. Special thanks go to the following contributions:

How to decouple state and UI (a.k.a. you don’t need componentWillMount)
This article by Michel Weststrate provided the initial inspiration for writing mobx-state-router. It explains the downsides of mixing State and UI and how to untangle the mess!

mobx-router
This library by Kitze is a good implementation of Michel Weststrate's ideas. I have borrowed some concepts from this implementation and then added my own. Thanks Kitze!

router5
This is a more extensive library for routing. It's unique feature is that routes are organized as a tree, made of segments and nodes. It aims to be framework agnostic and uses middleware and plugins to adapt to different frameworks. Of course, with flexibility comes complexity. mobx-state-router makes some choices for you to keep the overall learning curve simple.
