ESLint and Prettier

Hello amazing folks!🙂

Let's discuss something interesting today.

Let's understand what and why about Eslint and Prettier.

Imagine working over a project with more than 10 developers to achieve a vision 🧑‍💻. After 3 months you realize how messy things are now 🤒.

Funny part is even the person who wrote the code is confused in their own code 😂.

Want to avoid such scenario ? 😶

Form a structure which everyone will follow while writing their codes to make it easily understandable by everyone ✌. Sounds easy right ? But will everyone follow those things that seriously 🤔!

Think about someone getting added to the team. The person is a little freedom lover and mostly forgets to follow those set of rules. 😐

Hmm... code getting messed slowly right ?

Ya that's what Eslint and Prettier comes into play 😃. Eslint and Prettier are used to format the whole codebase into some set of rules.

Like there should not be any console log while pushing any code to production . Mainly done to ensure there is no printing of sensitive data on the logs.

Want to have a peak on how it looks ?

{
    "semi": true,
    "tabWidth": 2,
    "printWidth": 100,
    "singleQuote": true,
    "trailingComma": "none",
    "jsxBracketSameLine": true
}

Here's a peak of the configuration of the Prettier . You can see there are rules which can be made true based on your need.

{
    "rules": {
        "semi": ["error", "always"],
        "quotes": ["error", "double"]
    }
}

A small peak of Eslint , you can set types as warning or error. Forcing developers to follow a proper structure of coding.

I know ! I know !

Many people will think why force some rules while coding to developers. Let them code freely without any rules and restrictions 🤔.

I also used to believe the same !

But when I was working over a project with other developers, I understood how difficult it becomes when you have to read others messy code 🙍‍♂‍.

I know maybe it's sometimes painful but it's worthed. As clean coding is always tough for developer but when the project becomes large it becomes very easy for new developers and the existing developers to work on it 😉.

I would say. Just try it , I can give you guarantee you will fall love with it 👍.

And at last I want to say 👇

Keep coding #️⃣ , keep rocking 🚀
