helmet VS ESLint

Helmet is an npm package that includes middleware to handle and filter out malicious request headers (exploiting XSS vulnerabilities or clickjacking, for example). You can utilize Helmet's default configuration or customize it based on your needs following the instructions provided here.

By default, NuxtSecurity will set security response headers to match the values recommended by OWASP and a popular Express.js middleware called helmet.

Utilize security headers and middleware to add another layer of security to your Node.js application. Tools like Helmet.js can help you set secure HTTP headers, while middleware can assist in filtering and sanitizing user inputs.

Helmet helps “sanitise” the input, which might not have come from the UI directly. Mongoose is what is known as an Object Document Modelling (ODM), which defines a structure (schema) for the stored data, making it easier to manage in Express. These additions have been omitted from our example stack purely to simplify the tutorial and focus on the fundamental tiers and interfaces.

If you can repro the issue with a minimal tsconfig, with nothing but an import statement then it's probably something the maintainers of helmet would like to see. There's also this (recent) issue I saw looking at their queue -- maybe related? https://github.com/helmetjs/helmet/issues/424 ...

You can learn more about each header and how to configure them in the Helmet documentation.

These days I only use middleware if it's global and has no outputs. Helmet comes to mind.

ESLint: A pluggable and configurable linter tool for identifying and reporting on patterns in JavaScript.

Automating code checks with static code analysis allows us to enforce code styling effectively. By integrating tools into our workflow, we can identify errors at an early stage, while coding instead of blocking us at the end. For instance, flake8 checks Python code for style and errors, eslint performs similar checks for JavaScript, and prettier automatically formats code to maintain consistency.

If you're a developer, you're surely familiar with Prettier and ESLint. With over 8 years of existence, they have established themselves as references in the JavaScript ecosystem.

eslint is used to avoid code errors

No lint errors: The committed code does not contain any lint errors (eslint).

Let’s walk through the steps for a one-time setup to configure husky pre-commit and pre-push hooks, ESLint with code styles conventions, prettier code formatter, and lint-staged. Husky automatically runs a script on each commit or push. This is useful for linting files to enforce code styles that keeps the entire code base following conventions.

1. Lack of Static Code Analysis Static code analysis tools like TypeScript and ESLint play a crucial role in identifying and preventing bugs. TypeScript provides static typing, enhancing the robustness of the code. ESLint detects issues and enforces coding standards. The absence of these tools can significantly elevate the likelihood of bugs due to the lack of early detection and guidance provided during development.
