Extending zlib.DeflateRaw via non-class-keyword doesn't work. You can see this in action with this example:
'use strict'
const zlib = require('zlib');
const inherits = require('util').inherits;
function NotInitialized (options) {
zlib.DeflateRaw.call(this, options);
this.prop = true
}
inherits(NotInitialized, zlib.DeflateRaw);
console.log(new NotInitialized())The above prints out NotInitialized { prop: true }
What I expected it to do, was what this example does:
'use strict'
const zlib = require('zlib');
class Initialized extends zlib.DeflateRaw {
constructor (options) {
super(options)
this.prop = true
}
}
console.log(new Initialized())Not doing this initialization means that many stream operations result in crashes. (For example, pipe.)
This shows up in the real world with crc32-stream.
