Trying to deploy Strapi CMS with TypeScript to Railway and get: "Cannot find module 'typescript'"

Details

Trying to deploy strapi CMS written in TypeScript to Railway. I know there's a JavaScript Template, annoyingly there's not a TypeScript Template and there's nothing on the docs about deployment to Railway with TypeScript.

Error logs from Railway

Here's the error logs from railway. I think it might be trying to compile the JavaScript files but I've set the compiler to ignore node modules.

What I've Tried

I've followed the instructions on deploying with TypeScript, my tsconfig.json should be fine. I've added the additional environment variables but it seems like that has nothing to do with the error logs.

Any help would be much appreciated as I would rather not go with the JavaScript version.

Solution

  • Figured it out, it wasn't included in the docs, but they literally hadn't installed typescript as a dependency. Going to file an issue with Strapi now. Should've realized this sooner. Oh well 🤷‍♂️.

    If anyone else encounters this just do an npm install typescript. That fixed everything for me.
