Caching Examples

[jwaldrip]

Are there good examples for FileStore and NetworkStore cache configurations in metro?

Are there any updates on this after two years?

I've managed to use FileStore on my project.

If you check this file, you will notice that the metro-cache module exports the FileStore class.

No documentation is given of the options needed to create a new instance of the FileStore, but inspecting on the constructor of the FileStore class, I concluded that the root option is the directory where the cache will be saved.

My goal was to save Metro's cache on the project's root directory, so that I could cache it between builds on CircleCI. Therefore, my metro.config.js on a React Native / Expo (managed) project looked like this:

const { resolve } = require('path');
const { FileStore } = require('metro-cache');

module.exports = (async () => ({
  cacheStores: [
    new FileStore({ root: resolve(__dirname, '.metro-cache') }),
  ],
}))();

Anyway, I can't see the NetworkStore class on the metro-cache package, maybe the HttpGetStore or HttpStore can fullfil that role?

Hope it helps
