To fix Babel unexpected token import when running mocha tests with JavaScript, we add the @babel/preset-env library.
To install it, we run
npm install @babel/preset-env --save-dev
Then in the .babelrc file, we add
{
"presets": ["@babel/preset-env"]
}
to add the Babel preset to clear the syntax error.
To fix Node js Error: Protocol "https:" not supported. Expected "http:", we use https.get method.
For instance, we write
const http = require("http");
const https = require("https");
const url = new URL("https://www.example.com");
const client = url.protocol == "https:" ? https : client;
const req = client.get(url, (res) => {
console.log(res);
});
to get the client according to the url‘s protocol.
We use the https client if it’s https and http if it’s http.
Then we call get with the client for the right protocol to make the get request.
To run npm http-server with SSL, we create a certificate and use that to run the server.
To do this, we run
brew install mkcert
brew install nss
to install mkcert
Then we go to our project directory and run
mkcert 0.0.0.0 localhost 127.0.0.1 ::1
to create a certificate.
Then we run the server with our certificate with
http-server -S -C cert.pem -o
To fix Vue js error: Component template should contain exactly one root element, we should wrap our elements with one root element in our template.
For instance, we write
<div>
<div class="form-group">...</div>
<div class="col-md-6">...</div>
</div>
to wrap a div around the other divs to clear the error.
To fix ‘TypeError: is not a function’ error in Node.js, we should make sure the variable is a function.
For instance, we write
module.exports = functionName
to export the functionName function in function.js.
Then we require it with
const functionName = require('./function')
Now we can call functionName in our code.
