 1 | # vite-plugin-cross-origin-isolation
 2 | 
 3 | A vite plugin for enabling cross-origin-isolation for dev server.
 4 | 
 5 | ## Why
 6 | 
 7 | `Cross origin isolation` is required for `SharedArrayBuffer`.
 8 | 
 9 | Using this plugin, in local dev server, functions that rely on SAB can be enabled and tested.
10 | 
11 | > Edit 2023:
12 | >
13 | > The motivation of this plugin was mainly for my project [Glicol: a collaborative music programming language](https://glicol.org)
14 | >
15 | > But now there are some "official" ways to do it, see [here](https://github.com/chaosprint/vite-plugin-cross-origin-isolation/issues/3).
16 | 
17 | 
18 | ## Usage
19 | 
20 | First install it in your vite project:
21 | 
22 | `npm i -D vite-plugin-cross-origin-isolation`
23 | 
24 | Then, in `vite.config.js`:
25 | 
26 | ```
27 | import crossOriginIsolation from 'vite-plugin-cross-origin-isolation'
28 | 
29 | export default {
30 |     plugins: [
31 |       // other plugins...
32 |       crossOriginIsolation()
33 |     ]
34 | }
35 | ```
36 | 
37 | If this doesn't work, try this instead:
38 | ```
39 | import { defineConfig } from "vite";
40 | 
41 | export default defineConfig({
42 |   plugins: [
43 |     {
44 |       name: "configure-response-headers",
45 |       configureServer: (server) => {
46 |         server.middlewares.use((_req, res, next) => {
47 |           res.setHeader("Cross-Origin-Embedder-Policy", "require-corp");
48 |           res.setHeader("Cross-Origin-Opener-Policy", "same-origin");
49 |           next();
50 |         });
51 |       },
52 |     },
53 |   ],
54 | });
55 | ```
