distributed-node's Issues

Chapter 1: event loop with different result

page number: 13
node: v14.17.3
macOs Big Sur: Version 11.6

const sleep_st = (t) => new Promise((r) => setTimeout(r, t)); 
const sleep_im = () => new Promise((r) => setImmediate(r));
    (async () => {
      setImmediate(() => console.log(1));
      console.log(2);
      await sleep_st(0);
      setImmediate(() => console.log(3));
      console.log(4);
      await sleep_im();
      setImmediate(() => console.log(5));
      console.log(6);
      await 1;
      setImmediate(() => console.log(7));
      console.log(8);
})();

log out:

setImmediate(() => console.log(1))
console.log(2)

CA certificate error

Example: 2-9., How to be your own Certificate Authority
Error in curl call: curl http://localhost:3000
{
"code": "DEPTH_ZERO_SELF_SIGNED_CERT",
"error": "Internal Server Error",
"message": "request to https://localhost:4000/recipes/42 failed, reason: self signed certificate",
"statusCode": 500
}

In Example 2-8 It's ok! In 2-9 no ok!

I added the code below to solve in "consumer-https-basic.js"
process.env['NODE_TLS_REJECT_UNAUTHORIZED'] = 0;

/shared/tls/basic-certificate.cert missing in repo ?

------------------------------- update------------------
Never mind : ignore : see chapter two . for commands to create certificate
