To fix "nodemon" not recognized with Node, we’ve to install the nodemon package.

To do this, we run

npm install -g nodemon

to install nodemon globally with npm install -g.

To fix ‘node’ is not recognized as an internal or external command error, we add the Node executable folder to the PATH environment variable.

For instance, we run

SET PATH=C:\Program Files\Nodejs;%PATH%

to add the Node executable folder to the PATH with SET on Windows.

To require from URL in Node.js, we use the require-from-url package.

To install it, we run

npm install require-from-url

Then we use it by writing

const requireFromUrl = require("require-from-url/sync");
const module = requireFromUrl("http://example.com/nodejsmodules/myModule.js");

to call requireFromUrl with the URL of the module to return the module.

To fix Node npm: command not found in bash, we install npm.

To do this, we run

apt-get install -y npm

to install npm with apt-get install.

To make simple API calls with Node.js, we use the http module.

For instance, we write

const http = require("http");
const client = http.createClient(3000, "localhost");
const request = client.request("PUT", "/users/1");
request.write("stuff");
request.end();
request.on("response", (response) => {
  // ...
});

to call createClient to create a client object.

Then we call request to start a put request to the /users/1 URL.

Then we call write to write the request body.

And we call end to send the request.

We call on to listen for the 'response' event which is triggered when we receive a response.
