What mistakes do beginners do when they create Restful APIs?

Muhammad — Sat, 08 Jun 2024 11:00:44 +0000

Their APIs crash the server when an error occurs inside an API endpoint. In a correctly made API, the server does not crash rather it continues running in case of an error inside an API endpoint. Do error handling by using .catch or try-catch blocks.

How to send email from my Node JS app using my Gmail account?

Muhammad — Mon, 10 Jul 2023 11:26:14 +0000

First, 3 methods exist in 2023:-

Using the Less Secure App Option: (it was shutdown themselves by Google recently) Not Recommended
Using App Passwords: In 2023, you can not use nodemailer with simple configuration since Google does not allow doing so and the smalll caveat of App passwords is not recommended either by me. Access it by clicking https://myaccount.google.com/u/2/apppasswords Not Recommended
Using OAuth Recommended

Secondly, I will show the Google-recommended way of sending from you Node JS app an email using your Gmail account.

Step 1. Create a project in Google Cloud console
Step 2. Turn on Gmail API in "APIs and Services"
Step 3. Configure the "OAuth Consent Screen"
Step 4.

Does 'npm update' change the version numbers in the package.json file?

Muhammad — Sat, 24 Jun 2023 21:11:07 +0000

Short answer:

No, npm update does NOT change the version numbers in the package.json file to updated version numbers.

Long answer:

Running npm updatedoes not update the version numbers in the package.json file.
However it does change the version numbers in the "node_modules/packagename" field of the respective packages listed in the "packages" key and the dependecies in the "dependencies" keys in the package-lock.jsonfile.

What is INLINE_RUNTIME_CHUNK environment vairable?

Muhammad — Wed, 10 May 2023 23:20:23 +0000

When you run npm run build for a React app, this will prevent addition of inline JS into the build folder's index.html and create and attach separate JS files instead.

To use this environment variable, edit the build command as follows:

“build”: “INLINE_RUNTIME_CHUNK=false react-scripts build”,
If you rebuild your project, the generated index.html will contain no reference to inline JavaScript code.

Note:- For me I was getting error 'INLINE_RUNTIME_CHUNK' is not recognized as an internal or external command, operable program or batch file. when I added it directly in the script. I have to check the issue but I think in Windows, we cannot set env variable directly in a script and have to put it in a separate .env file.

Does React's npm run build add inline scripts in the build folder's index.html?

Muhammad — Wed, 10 May 2023 23:03:44 +0000

No, as of 11-May-2023, React does NOT add any inline scripts into the build folder's index.html file.

The build folder's index.html file includes an external JS file instead.

However in the previous versions before React 16 it did so, and still some third-party dependencies might do so as well. But React itself does not anymore.

Does react build command automatically put all files inside public folder to inside build folder?

Muhammad — Tue, 09 May 2023 00:46:18 +0000

Yes, by default, when you run npm run build , the create-react-app build process will copy all files in the public folder to the build folder when creating a production build. This includes any HTML files, images, or other static assets that are placed in the public folder.

  return x + y + z;
}

const numbers = [1, 2, 3];

console.log(sum(...numbers));
