ImJoy RPC

Usage

Load the library to the browser

<script
  type="text/javascript"
  onload="imjoyRPC.setupRPC()"
  src="https://cdn.jsdelivr.net/npm/imjoy-rpc@0.3.35/dist/imjoy-rpc.min.js"
></script>

Or, you can use the npm module:

npm install imjoy-rpc

import { imjoyRPC } from 'imjoy-rpc';

imjoyRPC.setupRPC({name: 'My Awesome App'}).then(api => {

})

imjoyRPC.waitForInitialization

This function is used to setup a base frame for running plugins. It will send imjoyRPCReady signal to the imjoy-core and listen for the initialize signal. Once received, it will call setupRPC with the config from the imjoy-core:

<script
  type="text/javascript"
  onload="imjoyRPC.waitForInitialization()"
  src="https://cdn.jsdelivr.net/npm/imjoy-rpc@0.3.35/dist/imjoy-rpc.min.js"
></script>

If needed, the authentication will also be done in this step (see config below).

config

You can optionally pass a config object into the function imjoyRPC.waitForInitialization(config)

• config.credential_required: boolean, whether your RPC app requires credentials
• config.credential_fields: array(of object), what are the fields required for the credentials, the properties of the objects will be used to generate HTML <input> field, it should contain label, id, value(the default value), type(any type supported by <input>, e.g.: text, number, password). For example: [{id: 'username', label: 'User Name', value: '', type: 'text'}, {id: 'password', label: 'Password', value: '', type: 'password'}].
• config.verify_credential: function, a function to check if the submitted credential is valid
• config.target_origin: string, the target origin required to connect to the RPC app, it's mandatory to set an explicit origin.

imjoyRPC.setupRPC

Setup ImJoy RPC manually:

imjoyRPC.setupRPC({name: 'My Awesome App'}).then((api)=>{
    // use the api object to interact with imjoy-core
