How to use TypeScript in a Functions (serverless) Project

Posted on September 4, 2022

I’m getting familiar with the new Functions offering and I see a variety of languages supported. Since my project is heavily typed, I would like to use TypeScript instead of vanilla JavaScript. I cannot find any example projects.

Is this even possible or with how Functions are build, it can only be JavaScript within the repo that will be tied to “Apps” for production use?

I’ve been working on a CLI library (docts) which enhances the development experience for Typescript function projects.

It allows you to:

Create a new TS project using a familiar file structure
Add/Remove functions to/from your project with automatic project.yml update
Manage all function dependencies from the project package.json instead of individual package.json
Build your project to get the packages which can then be deployed on App Platform or a function namespace

Check it out on Github and on NPM

If you find it helpful, kindly leave a star on the project

Hey @kisonay,

I don’t think that this is possible as of the time being.

The best thing to do to get your voice heard regarding this would be to head over to our Product Ideas board and post a new idea, including as much information as possible for what you’d like to see implemented.

Hope that helps!

Currently I’m using in a “hacky” way, it’s not ideal, but works… My build script on package.js is:

npm install typescript && tsc my_script.ts && npm remove typescript
