I'm currently facing a slight confusion with the got module, available at https://www.npmjs.com/package/got. The sequence and structure of functions within this module has got me puzzled. It's clear that you can chain listeners and functions together like this:
got.stream(link)
.on('response', resp => {
if (resp.statusCode != 200) this.emit('error', '!200')
})
.on('error', err => {
console.log(err)
})
.pipe(somewhere)
The request module also utilizes this technique. However, my question is how can one avoid using .pipe if they only want it to occur under the condition resp.statusCode != 200? Given its prevalence in various request modules, there must be a fundamental concept associated with it that I haven't quite grasped.
