创建代理服务器到 NPM 注册表 [英] Create proxy server to NPM registry

问题描述

我正在尝试创建自己的 local-npm 版本

I am trying to create my own verion of local-npm

我有这个简单的 http 服务器:

I have this simple http server:

#!/usr/bin/env node
'use strict';

import http = require('http');

const s = http.createServer(function (clientRequest, clientResponse) {

  if (clientRequest.url === 'x') {
    clientResponse.write('retrieve the tarball from local fs');
    clientResponse.end();
    return;
  }

  const proxy = http.request({
      hostname: 'https://registry.npmjs.org',
      port: 80,
      path: clientRequest.url,
      method: clientRequest.method
    },
    function (res) {
      res.pipe(clientResponse);
    });

  clientRequest.pipe(proxy);

});

s.listen(3441);

在本地终端中，我运行:

In a local terminal, I run:

npm config set registry "localhost:3441"

我也跑这个:

npm set registry "localhost:3441"

为了确认它有效，我这样做:

and to confirm it worked, I do:

$(npm get registry) => "localhost:3441"

但是当我运行 npm install 时，代理没有拦截任何东西，一切都转到 NPM.

but then when I run npm install, nothing gets intercepted by the proxy, everything just goes to NPM.

我做错了什么?

推荐答案

所以设置注册表与代理有点不同.

So setting the registry is a bit different to a proxy.

设置注册表会从设置的注册表中请求一个包；如果设置为默认值，npm registry 将收到一个请求，但是如果设置了其他内容，它将收到请求.

Setting the registry will request a package from the set registry; if it is set to the default, npm registry will receive a request, however if something else is set, that will receive request.

或者，设置代理将允许通过某个域访问设置的注册表.这是我必须在工作中设置的 npm 才能工作.

Alternatively, setting the proxy will allow the set registry to be accessed via a certain domain. This is what I have to set at work for npm to work.

npm config set proxy http://proxy.company.com:8080
npm config set https-proxy http://proxy.company.com:8080

ref

设置注册表几乎相同.

Setting the registry is pretty much the same.

npm config set registry http://localhost:3441
