mobx-remotedev

Remote debugging for MobX with Redux DevTools extension (and remotedev coming soon)

Installation

1. Get the extension

1.1 For Chrome

• from Chrome Web Store
• or build it with npm i & npm run build:extension and load the extension's folder ./build/extension
• or run it in dev mode with npm i & npm start and load the extension's folder ./dev.

1.2 For Firefox

• from AMO
• or build it with npm i & npm run build:firefox and load the extension's folder ./build/firefox.

1.3 For Electron

• just specify REDUX_DEVTOOLS in electron-devtools-installer.

1.4 For other browsers, for React Native, hybrid, desktop and server side apps

• Coming...

2. Install the library

npm install --save mobx-remotedev

Usage

import remotedev from 'mobx-remotedev';
// or import remotedev from 'mobx-remotedev/lib/dev'
// in case you want to use it in production or don't have process.env.NODE_ENV === 'development'

const appStore = observable({
  // ...
});

// Or
class appStore {
	// ...
}

export default remotedev(appStore);

See counter and todomvc examples.

API

remotedev(store, [config])

• arguments
  • store observable or class to be monitored. In case you want to change its values (to time travel or cancel actions), you should export its result as in the example above (so we can extend the class).
  • config object (optional as the parameters bellow)
    • name string - the instance name to be showed on the monitor page. Default value is document.title.
    • onlyActions boolean - set it to true to have a clear log only with actions. If MobX is in strict mode, it is true by default. Don't forget about async actions.
    • shouldStringify boolean - set it to true when having circular references or special types like ImmutableJS. By default is false.
    • filters object - map of arrays named whitelist or blacklist to filter action types. You can also set it globally in the extension settings.
      • blacklist array of (regex as string) - actions to be hidden in DevTools.
      • whitelist array of (regex as string) - all other actions will be hidden in DevTools (the blacklist parameter will be ignored).
    • remote boolean - set it to true to have remote monitoring via the local or remotedev.io server.
    • hostname string - use to specify host for remotedev-server. If port is specified, default value is localhost.
    • port number - use to specify host's port for remotedev-server.

Exclude / include DevTools in production builds

By default use

import remotedev from 'mobx-remotedev';

It will work only when process.env.NODE_ENV === 'development', otherwise the code will be stripped.

In case you want to use it in production or cannot set process.env.NODE_ENV, use

import remotedev from 'mobx-remotedev/lib/dev';

So, the code will not be stripped from production bundle and you can use the extension even in production. It wouldn't affect the performance for end-users who don't have the extension installed.

FAQ

How to monitor (show changes) for inner items

Use remotedev function for them as well. Example

How to set data correctly when time traveling

By default it will try to set the properties of the class or observable object, but, if you have an importState method, it will be used. Example

How to disable computations when time traveling

Check __isRemotedevAction of your class or observable object, which will be set to true when it's a monitor action. Example

How to handle async actions

Use runInAction and don't forget about the second / third parameter which will be this if you're using arrow functions. Example
