fs-cache-middleware

A streaming cache for any filesystem

npm install fs-cache-middleware

Similar to express-asset-file-cache-middleware, but doesn't require express and supports streaming payloads.

Usage

const fileCacheMiddleware = require('fs-cache-middleware')

function getAsset (url, params) { return { contentType: 'image/png', contentLength, // if known stream: streamingFetch('https://get/that/asset.png') } }

var cache = fileCacheMiddleware(getAsset, { maxSize: 10 1024 1024 * 1024 cacheDir: '/tmp' })

http.createServer(funcrion (req, res) { // Pass extra parameters on the fly with the request var params = { token: 'my-token' } cache(req, res, params, (err) => { if (err) { logger.error(err) res.statusCode = 500 res.end(err.message) } }) }
