PM2 VS ts-migrate

Start by registering the app using the official guide.

Run the application using PM2 (ref: Process manager for Node.js)

There are plenty of ways to accomplish this: Docker, Kubernetes, Pulumis, etc., but I don’t like to add too much complexity. So for a basic app, I like to use PM2, a Node.js process manager with great features, including the ability to run our app in the background.

This project will consist of a single "index.js" file that you can deploy anywhere. I recommend using an Nginx reverse proxy and pm2 to keep the service running.

Your app should be running now. To be able to run the app in the background, I will use pm2. Stop your application using "Ctrl + C" and install pm2

https://www.npmjs.com/package/pm2 I found this package. It looks good and solves my problem, I think.

Airbnb converted many millions of lines gradually using automation and wrote about it:

Are you migrating with ts-migrate?

When you migrate your entire project over to TypeScript, errors like "undefined is not a function", syntax errors, or reference errors should no longer exist in your codebase. Thankfully, this is not as daunting as it sounds. Migrating your entire Node.js application to TypeScript can be done incrementally so that you can start reaping the rewards immediately in crucial parts of the codebase. You can also adopt a tool like ts-migrate if you intend to perform the migration in one go.

Flow to ts — helps to produce raw migration from Flow to TS files and reduces monkey job. TS migrate — helps convert JS files to Typescript files. A great introduction can be found here.

💡 I typed it using ts-migrate ts-migrate is a tool I strongly recommend. It's been developed by Airbnb to help to migrate easily JavaScript projects to TypeScript.

When you decide to migrate, I recommend checking https://github.com/airbnb/ts-migrate may speed few migration steps (but it wont solve missing types/interfaces)

You can use AirBnb's ts-migrate tool or try a more direct tactic following the Migrating from JavaScript guide.
