npm http软件包仅提供package.json，没有javascript文件

Question

I installed a npm package that had 'http' as a dependency, so I installed that as well. All that was downloaded by npm for 'http' was a package.json file which referenced a non-existent index.js file. Is the index.js indeed missing from package.json or am I doing something wrong?

I'm using systemJS as a library loader.

TL;DR: you can't run server-side modules inside a browser.

From what I understand, you're trying to use server-side JavaScript modules inside of a browser, which isn't going to work. Browser have (very) limited abilities to set up network connection, or read from local file systems.

The http dependency that you're refering to is part of the Node standard library. So for Node apps, running server-side, it's always available.

In your case, you assumed that because require('http') didn't work (in the browser), you needed to install a separate package for that ( this package ).

But even if that package was working properly (it isn't), it wouldn't have worked inside of a browser because it depends on other modules inside the Node standard library, that also aren't available in a browser.

I don't know if CouchDB has a REST API itself that you would be able to use from the browser, but if not, you're going to have to implement a server-side API that will act as go-between between the browser and CouchDB.

From the browser, to talk to CouchDB, try the PouchDB library ( https://pouchdb.com/ ) and put the URL to your CouchDB in the constructor. It's intended for connecting to a local PouchDB (javascript implementation of CouchDB) but their APIs are identical. Or, try actually using a local PouchDB and then syncing between the two databases.
