sp-rest-proxy - SharePoint REST API Proxy for local Front-end development tool-chains

NPM

npm version Downloads Build Status FOSSA Status Gitter chat

Allows performing API calls to local Express application with forwarding the queries to a remote SharePoint instance.

Original concept of the proxy was created to show how it could be easy to implements real world data communications for SharePoint Framework local serve mode during web parts debug without deployment to SharePoint tenant. Now the tool is used with multiple teams for modern front-end solutions rapid development.

In a nutshell

Supports SPFx and PnP JS

Supported SharePoint versions

Development paradigms

Supports proxying

Proxy modes

Socket proxying allows to forward API from behind NAT (experimental).

How to use as a module

1. Install NPM module in the project:

npm install sp-rest-proxy

2. Create server.js with the following code:

const RestProxy = require('sp-rest-proxy');

const settings = {
  configPath: './config/private.json', // Location for SharePoint instance mapping and credentials
  port: 8080,                          // Local server port
  staticRoot: './static'               // Root folder for static content
};

const restProxy = new RestProxy(settings);
restProxy.serve();

Configuration parameters cheatsheet

3. Add npm task for serve into package.json:

"scripts": {
  "serve": "node ./server.js"
}

Check if the path to server.js is correct.

4. Run npm run serve.

5. Provide SharePoint configuration parameters.

6. Test local API proxy in action.

How to develop

Install

1. Clone/fork the project:

git clone https://github.com/koltyakov/sp-rest-proxy

2. CMD to the project folder.

3. Install dependencies:

npm install

4. Build:

npm run build

5. Run the server:

npm run serve

or serve in TypeScript directly

npm run ts-serve

Prompts credentials for a SharePoint site.

6. Navigate to http://localhost:8080 (or whatever in settings)

7. Ajax REST calls as if you were in SharePoint site page context:

REST Client Example

8. Tests.

npm run test

Tests Example

Webpack Dev Server

/* webpack.config.js */
const RestProxy = require('sp-rest-proxy');

const port = process.env.WEBPACK_DEV_SERVER_PORT || 9090;

module.exports = {
  // Common Webpack settings
  // ...
  devServer: {
    watchContentBase: true,
    writeToDisk: true,
    port,
    before: (app) => {
      // Register SP API Proxy
      new RestProxy({ port }, app).serveProxy();

      // Other routes
      // ...
    }
  }
};

Rollup Dev Server

For Rollup-based workflows, e.g. Vite tools, please check community plugin: rollup-plugin-sp-rest-proxy.

TypeScript support

In early days of sp-rest-proxy, the library was written in ES6 and used module.exports which was kept after migrating to TypeScript later on for the backward compatibility reasons.

In TypeScript, it's better to import the lib from sp-rest-proxy/dist/RestProxy to get advantages of types:

import RestProxy, { IProxySettings } from 'sp-rest-proxy/dist/RestProxy';

const settings: IProxySettings = {
  configPath: './config/private.json'
};

const restProxy = new RestProxy(settings);
restProxy.serve();

Authentication settings

The proxy provides wizard-like approach for building and managing config files for node-sp-auth (Node.js to SharePoint unattended http authentication).

For more information please check node-sp-auth credential options and wiki pages. Auth settings are stored inside ./config/private.json.

PnPjs

sp-rest-proxy works with PnPjs (check out brief notice how to configure).

PnP JS + sp-rest-proxy

Load page context helper

sp-rest-proxy includes helper method for configuring page context - loadPageContext.

import { loadPageContext } from 'sp-rest-proxy/dist/utils/env';
import { Web } from '@pnp/sp';

// loadPageContext - gets correct URL in localhost and SP environments
loadPageContext().then(async () => {

  // In both localhost and published to SharePoint page
  // `_spPageContextInfo` will contain correct info for vital props

  // PnPjs's Web object should be created in the following way
  const web = new Web(_spPageContextInfo.webAbsoluteUrl);

  // Then goes ordinary PnPjs code
  const batch = web.createBatch();

  const list = web.getList(`${_spPageContextInfo.webServerRelativeUrl}/List/ListName`);
  const entityName = await list.getListItemEntityTypeFullName();

  [1, 2, 3, 4].forEach((el) => {
    list.items.inBatch(batch).add({
      Title: `${el}`
    }, entityName);
  });

  await batch.execute();
  console.log('Done');

}).catch(console.warn);

JSOM (SharePoint JavaScript Object Model)

JSOM can be used in local development mode with sp-rest-proxy with some additional setup.

The local development workbench page should contain JSOM init scripts:

<script type="text/javascript" src="https://github.com/koltyakov/sp-rest-proxy/raw/master/_layouts/15/1033/initstrings.js"></script>
<script type="text/javascript" src="https://github.com/koltyakov/sp-rest-proxy/raw/master/_layouts/15/init.js"></script>
<script type="text/javascript" src="https://github.com/koltyakov/sp-rest-proxy/raw/master/_layouts/15/MicrosoftAjax.js"></script>
<script type="text/javascript" src="https://github.com/koltyakov/sp-rest-proxy/raw/master/_layouts/15/sp.core.js"></script>
<script type="text/javascript" src="https://github.com/koltyakov/sp-rest-proxy/raw/master/_layouts/15/sp.runtime.js"></script>
<script type="text/javascript" src="https://github.com/koltyakov/sp-rest-proxy/raw/master/_layouts/15/sp.js"></script>
