strapi-middleware-upload-plugin-cache

Use case

• @strapi/provider-upload-local is in use for uploading assets via Media Library in Strapi (default)
• The need for configurable cache-control HTTP response headers (e.g. cache-control: max-age=1234) + ETag HTTP response header for each asset
• More information and differences between koa-static (used in @strapi/provider-upload-local) and koa-static-cache (used in this middleware-plugin) can be found here

Version 2.X.X+ of this library is NOT compatible with Strapi v3!

Please make sure to check out the Strapi v3 Docs for the installation & setup.

Setup

For Strapi, add a plugins.js file within the config folder

e.g.

touch config/plugins.js

containing

module.exports = {
  "upload-plugin-cache": {
    enabled: true,
    config: {
      maxAge: 86_400_000,
    },
  }
};

Starting Strapi in dev-mode should log the following:

[2022-02-22 22:22:22.222] debug: [upload-plugin-cache] Initializing ...
[2022-02-22 22:22:22.222] debug: [upload-plugin-cache] Middleware initialized for endpoint='/uploads/(.*)' [maxAge=300000]

Configuration Options

With the option dynamic: true files which are not cached on initializations are dynamically loaded. To avoid OOM errors a LRU-cache can be used. For config options of lru-cache use these docs and insert them at lruCache.

module.exports = {
  "upload-plugin-cache": {
    enabled: true,
    config: {
      maxAge: 86_400_000,
      dynamic: true,
      lruCache: {
        max: 1000
      },
    },
  }
};
