https-pool

A cached pool of https server for domains.

---

Install

$ npm i https-pool --save

Usage

https-pool is useful for getting https server without worry about forging certificates.

Just pass your CA certificate options into HttpsPool, and get a empty https server pool.

const HttpsPool = require("https-pool");
const fs = require("fs");
 
const key = fs.readFileSync(path.join(fixtures, "root.key"));
const cert = fs.readFileSync(path.join(fixtures, "root.crt"));
 
const httpsPool = new HttpsPool({
  key,
  cert,
  commonName: "example",
  countryName: "CN",
  ST: "SH",
  localityName: "SH",
  organizationName: "example.com",
  OU: "example.com"
});
 
// You can save the cert and key of root CA to let the client trust it.
const { key, cert } = httpsPool.CA;

You can get a https server like this ↓. That's enough for common usage. https-pool will take care of the cache logic, so worrying about your memory is unnecessary.

httpsPool.getServer(
  "www.foo.com",
  (req, res) => {
    // the listener for server.request event
    console.log(req.headers);
    res.send("ok");
  },
  _port => {
    // callback with a random available port
    console.log(typeof _port === "number");
  },
  // timeout for the new https-server
  3000
);
