An Express.js middleware to byte serve content
npm install --save partial-responsepartial-response inserts a method (sendPartial) on the response object.
It takes a file path as parameter, and will serve the file with proper Range headers.
Like so:
const pr = require('partial-response')
app.get('/cat-pic', pr, (req, res) => {
res.sendPartial('./cat-pic1.jpg')
})MIT
