@rrequire/client v0.0.6

See full documentation in the repo: https://github.com/MikeShi42/rrequire

why rrequire?

The 🚀 fastest ⚡️ way for web apps to start talking to servers. Connect your frontend to your backend with just 3 lines of code and zero configuration.

Enjoy familiar node module export syntax and ES6 import syntax to make your remote calls.

Warning: This package is still experimental and the API may change in-between minor versions.

Getting Started

Web Client

The rrequire client allows for easy calls from a web browser to a remote server implementing the JSON-RPC protocol (such as the @rrequire/server).

Install from npm:

npm install @rrequire/client

'Import' a remote function for use:

import rrequire from '@rrequire/client';

const { add } = rrequire('server/module');

async function myClientMethod(x) {
  console.log(await add(x, 5));
}

By default, rrequire will try to send requests to the current host (/).

All functions return Promises that will resolve to the value that's returned by the remote procedure (or reject if a problem occurs). It's recommended to use the async/await syntax for more concise code.

Note: As of this time, module names are not used to scope function imports.

Configuration

Import the config function to globally set configs for future RPC requests.

import rrequire, { config } from '@rrequire/client';

config({ remoteLocation: 'http://localhost:8080' });

Advanced Usage: Avoiding ES6 Proxy

The usage of Proxy in production can cause problems for browsers that do not yet support Proxy. The Proxy object is used to magically catch all property references at run time (ex. module.function), allowing for easy ES6-like import syntax and minimal overhead. Since there is no polyfill for Proxy, you must instead explicitly define which functions you expect to import from the remote server.

By passing in an array of function names into the rrequire function call, rrequire avoids using Proxy and creates a static object with all functions pre-defined according to the array.

Example

const {
    add,
    subtract,
} = rrequire('server/module', [
    // This array specifies which function names we're importing
    // It should match the above properties
    'add',
    'subtract',
]);
