IPC for Pear

npm install pear-ipc

API

const IPC = require('pear-ipc')

import IPC from 'pear-ipc'

const ipc = new IPC(opts)

Create a server/client IPC instance with automatic RPC method setting/handling configured via methods option.

Options

• socketPath <String> - Path to Unix socket / Windows pipe file
• connectTimeout <Number[ms]> - Fail after given milliseconds if unable to connect
• connect <Boolean>|<Function> - If truthy, attempt to connect. If a function, pear-ipc calls it to boot sidecar.
• methods <Array... { id: <Number[int]>, name: <String>, stream: <Boolean(false)>, send: <Boolean(false)> }> - an index of method descriptions. The order of methods (and their settings) must be consistent across all RPC instances using the same method set. The index of a method in the array is that methods uint identifier. ['myMethod'] and [{name: 'myMethod'}] are equivalent. Generated methods default to being request-based (stream:false and send:false). Setting send: true will generate a fire-and-forget method. Setting stream: true will generate a method that returns a [Streamx][https://github.com/mafintosh/streamx] stream response. For more complex cases, the api option can be used to wrap define the instance method. Base Properties and Base Methods are illegal RPC method names. See methods.js for example structure.
• api { [name]: (method) => (params) => <Stream|Promise|Any> } - Define outgoing methods on the RPC instance. Property names on the api object matching names in the methods array will be used to generate instance methods if provided. A tiny-buffer-rpc method object will be passed. Call any/all of method.request method.send or method.createRequestStream and make any other calls or alterations as needed.
• handlers - { [name]: (params) => <Stream|Promise|Any> } - Handle incoming calls. Property names on the handlers object matching names in the methods array passed the incoming params object. It is up to the handler to return the correct response for that method.
• stream <Duplex> - Advanced. Set a custom transport stream

Default RPC Methods

Default method declarations can be found in methods.js.

Base Methods

• ipc.ready() - IPC client connect to server / IPC server begin listening
• ipc.client(id) - get IPC server client instance by ipc.id
• ipc.ref() - reference as active handle
• ipc.unref() - unreference as active handle
• ipc.close() - close the client IPC instance / server IPC instance

Base Properties

• ipc.id - Instance ID
• ipc.clients - IPC server instance array of IPC client instances
• ipc.hasClients - Boolean. Whether IPC server has client instances
• ipc.userData - Default: null. Set ipc.userData to an object to efficiently hold client metadata
• ipc.opening - Promise that resolves on open
• ipc.opened - Boolean. IPC client has connected / IPC server has started
• ipc.closing - Promise that resolves on close
• ipc.closed - Boolean. IPC client has disconnected / IPC server has shutdown
