rollup-plugin-sp-rest-proxy

Rollup / Vite plugin that wires sp-rest-proxy into the dev server so SharePoint REST calls resolve locally while you build.

Compatibility

• Built and tested against Vite 7.x (Rollup 4.x, Node 18+).
• Use rollup-plugin-sp-rest-proxy@^2 for Vite 5–7 projects.
• If you are pinned to Vite 4 or earlier, install rollup-plugin-sp-rest-proxy@^1, which keeps the old default export.

Install

npm install -D rollup-plugin-sp-rest-proxy
# or
pnpm add -D rollup-plugin-sp-rest-proxy

Usage

import { defineConfig } from "vite";
import { RollupPluginSPRestProxy } from "rollup-plugin-sp-rest-proxy";

const rollupPluginSPRestProxy = new RollupPluginSPRestProxy();

export default defineConfig({
  server: {
    proxy: {
      ...rollupPluginSPRestProxy.viteProxySetting(),
    },
  },
  plugins: [rollupPluginSPRestProxy.rollupPlugin()],
});

import { defineConfig } from "vite";
import { RollupPluginSPRestProxy } from "rollup-plugin-sp-rest-proxy";

export default defineConfig(
  RollupPluginSPRestProxy.mergeViteConfig({
    /* your vite config */
  })
);

Options

• The constructor accepts the underlying sp-rest-proxy settings; defaults are { port: 9090, hostname: "localhost" }.
• viteProxySetting merges the SharePoint _api proxy into any existing Vite proxy map while preserving your other entries.

Notes

• v2 switches to named exports only; update imports accordingly.
• Dependencies are bumped to sp-rest-proxy@^3.3.6, portfinder@^1.0.28, and Vite 7.x to stay current with upstream fixes.
