How can you improve your front-end code quality with React or Angular?

Reusablity is important The most important, or one of the most important points in using frameworks like React, is the reusability of components. If you don't follow this, you will soon have a project that confuses people and no one can develop it.

I do agree. One more benefit of using the same code formatter within the team is, it can also help you avoid merge conflicts (caused only by using different formatters by different developers).

Always read doc of framework, learn at least one UI framework, read new updates and try to implement in ongoing projects, stay in touch with other FE developers, at your free time navigate to forums and try to help other developers.

It's essential for the entire team to align on the same tool and configuration, especially when committing code. If different team members use varying formatting rules, the change logs can be flooded with unnecessary format changes, distracting from the actual code alterations. By adhering to a shared set of formatting rules, teams can ensure that commits and change logs remain focused on the real code changes, leading to cleaner collaboration and a more streamlined development workflow.

One thing I've found helpful about using a code formatter is. Ensuring that my code always adheres to a consistent style and avoids common syntax errors. An example I've seen of a code formatter improving code quality. Integrating Prettier into my React project automatically formatted the code on save, making the codebase more consistent and reducing the time spent on manual formatting.

When creating components you can think about how to keep presentation components separate from UI logic, so that you can easily switch presentation components in future without changing the UI logic.

It's also worth mentioning the concept of micro-frontends. Micro-frontends extend the idea of componentization, allowing different parts of a web application to be developed, tested, and deployed independently. This architecture not only aligns with the principles of component-based design but also provides greater flexibility and scalability. By breaking down the UI into more manageable and autonomous parts, teams can work on different sections of an application simultaneously without interfering with each other. Combined with the component-based approach, micro-frontends offer an advanced level of modularity that can further enhance code quality and development efficiency.

Use a component-based architecture. This means breaking down your code into reusable components. This will make your code more modular, maintainable, and scalable.

On top of reusability, this approach also helps while debugging the issues. Component based architecture also helps you to organise and maintain your code with better readability.

One thing I've found helpful about following a component-based architecture is. The ability to create reusable and isolated UI components, which enhances code quality and maintainability. Actually, I disagree with the notion that component-based architecture is only applicable to React and Angular. It's a versatile pattern that can be adapted to various frameworks and libraries, improving code organization and reusability.

In my experience, unit tests make developers more productive. Why run whole app, when you can run just the part of the app with unit test to fix bugs. And after writing tests, no more manual testing that part of app when making changes in future. Unit testing also works as documentation of code. Future developers can easily know what is expected from this part of the app.

In addition to implementing these testing practices, I would also recommend utilizing pre-commit Git hooks, especially for more sensitive branches in your repository. A pre-commit hook can be set up to run unit tests before allowing a commit or push, ensuring that only code that passes the tests is included in the branch. This can be particularly beneficial for protecting critical branches from untested or faulty code.

Test Driven Development (TDD) is a great approach to ensuring tests are written to meet the functionality of the feature request as well as reducing the cognitive complexity of the code that you’re writing - ensuring you’re writing only the code necessary to make the test pass.

Write unit tests. Unit tests can help you to verify that your components are working as expected. This will help you to catch bugs early and to prevent them from making their way into your production code.

TDD should come before the formatter and linters. TDD is not about testing. TDD is about Design. So don't be afraid to write tests first. Investing in good design patterns will pay off.

One more thing to keep an eye on is API calls which are being made while running the application. First of all, we should avoid any unnecessary api calls and make sure to use caching whenever possible. We can also focus on image and image sizes used by the application. Whenever possible, we should use svg formats for the images. With modern projects, we should also try to have unidirectional data flow.

One thing I've found helpful about optimizing performance and accessibility is... Enhancing both user experience and code quality by making applications faster and more inclusive. Actually, I disagree with the notion that performance and accessibility are optional... They are critical considerations that can impact a project's success and reach.

Some ways to get started - 1. Write meaningful names for functions and variable 2. Give proper names to constants. 3. Write modular code. Divide the functions into smaller functions. 4. Write helpers for logics used in components

Before raising pull request, you can review code yourself and ask yourself questions like, can other Developers easily understand these changes, if not, time to refactor.

so you have to develop a strong habit of seeing ways to improve, refactoring your code constantly. You should keep in mind more suitable patterns and abstractions, perhaps more laborious to implement. The bottom line is that there will probably be a good time in your development process to implement your code improvement ideas. But you can only recognize it by constantly working to find potential areas for improvement. Compare this process to finding the right angle for a good photo while keeping yourself in good physical shape through various exercises.

Using TypeScript. Trust me! It will be one of the best decisions you can make for your team ??. Once you get a hold of it, you never want to go back to plain JS. There're numerous benefits of TS, to name a few: 1. Static Typing: We can detect errors earlier, resulting in more reliable code and easier to maintain 2. Code Readability: Specified data types help the code more self-documenting, thus improving clarity and consistency in large projects 3. Rich IDE support: Automatic code completion, refactoring, and type inference are supported out-of-the-box

Document, document, document. Comment your code. JSDoc decorators for functions allow you to share usage examples and give more meaningful explanations, and integrates nicely with the VSCode Intellisense. Part of your pull request template should require acknowledging that the README and other related docs are updated, and the PR reviewer should also ensure this is up to date before approving the PR and merging.

Set aside time to upgrade to the latest version as well as to make sure your dependencies are up to date. In addition, you will need time to reimplement existing code to avoid breaking changes in the API. Otherwise, you risk having deprecated code which has no upgrade path and possible security vulnerabilities. This should be planned in advance based on the release schedule of React or Angular.
