minipass-sized

A Minipass stream that raises an error if you get a different
number of bytes than expected.

USAGE

Use just like any old minipass stream,
but provide a size option to the constructor.

The size option must be a positive integer, smaller than
Number.MAX_SAFE_INTEGER.

``ts
import { MinipassSized } from 'minipass-sized'
// or:
// const { MinipassSized } = require('minipass-sized')
// figure out how much data you expect to get
const expectedSize = +headers['content-length']
const stream = new MinipassSized({ size: expectedSize })
stream.on('error', er => {
// if it's the wrong size, then this will raise an error with
// { found: , expect: , code: 'EBADSIZE' }
})
response.pipe(stream)
`

Caveats: this does not work with objectMode streams, and will
throw a TypeError` from the constructor if the size argument is
missing or invalid.
