Koa VS tsoa

Since "Express.js is an old framework that has not evolved for a long time. It's not a good choice for new projects since it can easily lead to security issues and memory leaks." -- H3. Which is also the case for Koa.

In this example, we're using the serverless framework to quickly set up the Lambda function along with an API gateway for the entry point. The lambda function is a simple Koa REST API with a few functional endpoints.

The initial step is to create our entry point, from where the page will be rendered. In this case, we will use the koa framework.

Koa.js: By the team behind Express, Koa.js utilized async/await for middleware, resulting in cleaner and more readable code.

Koa -Next Generation Node Microservice Framework

Backend is more tricky. - RESTful APIs I prefer Koajs - For a RPC/microsevice, I have only used gRPC - For a CLI, yargs and inquirer

There are lot of different frameworks out there. If you learn one, there is no guarantee that the next job you find will use the same. For example if you learn Express and the next one used Koa or Nest.

Koa.js is a minimal and flexible Node.js web application infrastruc­ture, which provides a robust set of features for web and mobile applica­tions. It is an open-source framework developed and maintained by the creators of Express.js, the most popular web framework for Node.js.

Tsoa is a popular TypeScript framework similar to Goa that you may encounter in the OpenAPI ecosystem. Speakeasy has a tutorial for it, too.

Currently i am using TSOA and loving it, it gives you automatic Open API specs and data validation based on typescript interfaces. I have used Nest on previous projects but I personally don't like the decorators hell that comes with Nest, and raw express/fastify are ok and easy to use but a pain in the ass on big projects to keep swagger, validations, interfaces and DTOs all in sync.

I'm curious if anyone here has played around with or used TSOA (https://github.com/lukeautry/tsoa)?

If you decide to go with Express/Typescript I would definitely check out TSOA. It's a nice way to build backend APIs with auto documentation.

We are using TSOA to generate the docs from the code, works pretty well. https://github.com/lukeautry/tsoa

This is the best project I’ve found to that for that - https://github.com/lukeautry/tsoa. Uses decorators mainly.

If there are other such projects, please share.

Hello, In the last month I built a REST API template in Typescript to quickly bootstrap new projects, I tried to use the most updated modules available, I've also included a "todo" sample just to showcase how all the things work together, the main modules that I've used are: - expressjs + tsoa that allows to easily generate the OpenAPI spec without any additional steps (just declare your controllers via typescript) - class-validator to validate body requests (this is also useful as the OpenAPI will be automatically generated based on the classes that you define) - Jest for testing, I've included also unit and integrations test samples with an in-memory database

Have a look at [TSOA[(https://github.com/lukeautry/tsoa). While far from perfect (I am on the lookout to find a better solution), gets the job done. And generating the entire routing is a pretty neat trick, so that's also that.

tsoa Lighter weight, but also great.
