Remix Plugin

The repository host the code required for remix-plugin. It's divided into two type of projects:

Engine: The code needed to host remix plugins in your project (used in remix-ide).
Plugin: The code that runs in a plugin.

Engine

Currently the engine can only run inside the web. A node version is coming for v0.3.0

If you want to implement the remix engine in your project checkout full documentation here

Plugin

Currently there are 3 types of plugin communication supported :

iframe (web)
websocket (web)
child_process (node)

If you want to create a plugin for remix-ide, checkout the documentation below.

Getting Started

This getting started is for building iframe based plugin (only supported by remix-ide for now).

Installation :

npm install @remixproject/plugin-iframe

or with a unpkg :

<script src="https://unpkg.com/@remixproject/plugin"></script>

Plugin Client

The plugin client is how you connect your plugin to remix.

To import ( the ES6 way) with NPM use:

import { createIframeClient } from '@remixproject/plugin'
const client = createIframeClient()

Or if you are using unpkg use:

const { createIframeClient } = remixPlugin
const client = createIframeClient()

Examples

You can find examples of plugins here :

Test inside Remix IDE

To test your plugin with remix:

Go to http://remix-alpha.ethereum.org. (if your localhost is over HTTP, you need to use http for Remix IDE).
Click on the plugin manager (Plug icon on the left).
Click on "Connect to a Local Plugin".
Fill the profile info of you plugin ().
Click on "ok".
A new icon should appear on the left, this is where you can find you plugin.

Client API

Loaded

PluginClient listen on a first handshake from the IDE before beeing able to communicate back. For that you need to wait for the Promise / callback onload to be called.

client.onload(() => /* Do something */)
client.onload().then(_ => /* Do Something now */)
await client.onload()

Events

To listen to an event you need to provide the name of the plugin you're listening on, and the name of the event :

client.on(/* pluginName */, /* eventName */, ...arguments)

For exemple if you want to listen to Solidity compilation :

client.on('solidity', 'compilationFinished', (target, source, version, data) => {
    /* Do Something on Compilation */
  }
)

⚠️ Be sure that your plugin is loaded before listening on an event.

See all available event below.

Call

You can call some methods exposed by the IDE with with the method call. You need to provide the name of the plugin, the name of the method, and the arguments of the methods :

await client.call(/* pluginName */, /* methodName */, ...arguments)

Note: call is alway Promise

For example if you want to upsert the current file :

async function upsertCurrentFile(content: string) {
  const path = await client.call('fileManager', 'getCurrentFile')
  await client.call('fileManager', 'setFile', path, content)
}

⚠️ Be sure that your plugin is loaded before making any call.

Emit

Your plugin can emit events that other plugins can listen on.

client.emit(/* eventName */, ...arguments)

Let's say your plugin build deploys a Readme for your contract on IPFS :

async function deployReadme(content) {
  const [ result ] = await ipfs.files.add(content);
  client.emit('readmeDeployed', result.hash)
}

Note: Be sure that your plugin is loaded before making any call.

Expose methods

Your plugin can also exposed methods to other plugins. For that you need to extends the PluginClient class, and override the methods property :

class MyPlugin extends PluginClient {
  methods: ['sayHello'];

  sayHello(name: string) {
    return `Hello ${name} !`;
  }
}
const client = buildIframeClient(new MyPlugin())

When extending the PluginClient you need to connect your client to the iframe with buildIframeClient.

You can find an exemple here.

Testing your plugin

You can test your plugin direcly on the alpha version of Remix-IDE. Go to the pluginManager (plug icon in the sidebar), and click "Connect to a Local Plugin".

Here you can add :

A name : this is the name used by other plugin to listen to your events.
A displayName : Used by the IDE.
The url : May be a localhost for testing.

Note: No need to do anything if you localhost auto-reload, a new handshake will be send by the IDE.

Publish your plugin on Remix IDE

To publish on Remix IDE, uou need to create a Profile for you plugin with the following field :

interface Profile {
  name: string, // The name of your plugin in camelCase (used inside client.call(name, method, payload)).
  displayName: string, // The name displayed by the IDE
  description: string, // A description to display in the IDE
  events: [], // Name of the events
  methods: ['sayHello'], // Name of the methods exposed by the plugin
  url: string, // URL where your plugin is hosted
  icon: string, // Url of the icon to display on tab
  location: 'mainPanel' | 'sidePanel' | 'none' // Where your plugin should be displayed in the IDE
}

API

Your plugin can interact with other plugins through the API. @remixproject/plugin provide a set of default plugins integrated inside the Remix IDE. Some of the APIs have to be used with caution. So they might ask the permission of the user.

Remix IDE API

List of native plugins exposed by Remix IDE

Click on the name of the api to get the full documentation.

API	Name	Permission	Description
File System	fileManager	✅	Manages the File System
Compiler	solidity	✅	The solidity Compiler
Editor	editor		Enables highlighting in the code Editor
Network	network		Defines the network (mainnet, ropsten, ...) and provider (web3, vm, injected) used
Udapp	udapp	✅	Transaction listener
Unit Testing	solidityUnitTesting		Unit testing library in solidity
Settings	settings	✅	Global settings of the IDE
Content Import	contentImport		Import files from github, swarm, ipfs, http or https.

This API is a Work In Progress and will be extended in the future.

External API

API	Name	Permission	Description
3Box	box		Decentralized storage.

Status

Every plugin has a status object that can display notifications on the IDE. You can listen on a change of status from any plugin using statusChanged event :

client.on('fileManager', 'statusChanged', (status: Status) => {
  // Do Something 
})

The status object is used for displaying a notification. It looks like that :

interface Status {
  key: number | 'edited' | 'succeed' | 'loading' | 'failed' | 'none'  // Display an icon or number
  type?: 'success' | 'info' | 'warning' | 'error'  // Bootstrap css color
  title?: string  // Describe the status on mouseover
}

If you want to remove a status use the 'none' value for key.
If you don't define type, it would be the default value ('info' for Remix IDE).

You can also change the status of your own plugin by emitting the same event :

client.emit('statusChanged', { key: 'succeed', type: 'success', title: 'Documentation ready !' })

The IDE can use this status to display a notification to the user.

Client Options

CSS Theme

Remix is using Bootstrap. For better User Experience it's highly recommanded to use the same theme as Remix in your plugin. For that you just have to use standard bootstrap classes.

Remix will automatically create a <link/> tag in the header of your plugin with the current theme used. And it'll update the link each time the user change the theme.

If you really want to use your own theme, you can use the customTheme flag in the option :

const client = createIframeClient({ customTheme: true })

Custom Api

By default @remixproject/plugin will use remix IDE api. If you want to extends the API you can specify it in the customApi option.

A good use case is when you want to use an external plugin not maintained by Remix team (3box plugin for example):

import { remixProfiles, IRemixApi } from '@remixproject/plugin'
interface ICustomApi extends IRemixApi {
  box: IBox;
}

export type CustomApi = Readonly<ICustomApi>;

export type RemixClient = PluginClient<any, CustomApi> & PluginApi<CustomApi>;

const customApi: ProfileMap<RemixIDE> = Object.freeze({
  ...remixProfiles,
  box: boxProfile
});
const client = createIframeClient({ customApi })

You'll need Typescript > 3.4 to leverage the types.

DevMode

Plugins communicate with the IDE through the postMessage API. It means that PluginClient needs to know the origin of your IDE.

If you're developing a plugin with your IDE running on localhost you'll need to specify the port on which your IDE runs. By default the port used is 8080. To change it you can do:

const devMode = { port: 3000 }
const client = createIframeClient({ devMode })
