Serverless-Boilerplate-Express-TypeScript VS ESLint

You can find more details in my open source boilerplate: https://github.com/ixartz/Serverless-Boilerplate-Express-TypeScript where I'm using TypeScript.

You can check out the GitHub repo for more details at: Node.js Boilerplate with Serverless and Prisma

Here is the link to the Node.js Boilerplate code: https://github.com/ixartz/Serverless-Boilerplate-Express-TypeScript

You can checkout the Serverless Boilerplate Typescript GitHub repo.

As you might know, AWS has recently announced AWS Lambda Function URLs. This is a new feature that allows you to deploy your lambda behind a HTTPS endpoint without API Gateway. So, no need to set up a API gateway with related cost associated to it or add complexity to your serverless architecture for a single lambda function. I'm the author of a Serverless Boilerplate Template that uses Express.js with AWS Lambda. Usually, I got a lot of questions on why I add Express.js to my boilerplate code. Indeed, adding Express.js with API Gateway is redundant and it's not necessary. It'll increase the deployed package size. Now with Lambda Function URLs, you don't need an API Gateway all the time. Without API gateway, all HTTP requests are sending to one lambda function. That means you need a Web framework to handle the request like Express.js. To be clear and avoid any confusion, API gateway is still a solution. But, based on your context and your needs, you can choose to use Lambda Function URLs and remove the API gateway. In the past, a lot of people were suggesting me to remove Express.js from my starter code. Now with Lambda Function, I'm not sure if it's a good idea to remove it from your boilerplate code. What is your thoughts on this?

ESLint: A linter that statically analyzes your code to quickly find problems and enforce coding standards. We used this at my organization for better code structure and standards.

As you may have heard, the JS ecosystem is trying to move away from tooling written in JavaScript like eslint, prettier and even tsc for more performant options.

ESLint is a popular JavaScript linter that helps developers identify and fix issues in their code. It enforces coding standards and best practices, making it easier to write clean, consistent, and maintainable code.

Don't forget that Ewan is the author of eslint[1], which started a wave, eventually resulted in 10x performance improvements in frontend tooling, and even recent TypeScript rewrite to go[2].

So, I had to test this new version in a personal project to learn how to use all these new things along with other technologies and tools I’ve used for a long time and also love, like VSCode, ESLint, Prettier, and a bunch of other. And I did, but there’s a catch which makes the whole “experimental” thing have more sense: you can only use this through ng test.

ESLint: A tool for identifying and reporting on patterns found in ECMAScript/JavaScript code

While ESLint is the go-to tool for code quality in JavaScript, it doesn’t provide any built-in rule for this.
