Strict TypeScript?

System Information
  • Strapi Version: ^4.11

Personally I’m new to Strapi and I was trying it out today with TypeScript. One of the first things I noticed was the TypeScript support seemed questionable/concerning:

  • tsconfig.json seems to extend @strapi/typescript-utils/tsconfigs/server which looks like this
    "$schema": "",
    "compilerOptions": {
        "module": "CommonJS",
        "moduleResolution": "Node",
        "lib": ["ES2020"],
        "target": "ES2019",

        "strict": false,
        "skipLibCheck": true,
        "forceConsistentCasingInFileNames": true,

        "incremental": true,
        "esModuleInterop": true,
        "resolveJsonModule": true,
        "noEmitOnError": true

It strikes me as odd that a brand new TypeScript project would not have the “strict” option turned on. The only reason I could expect this option to be turned off is if this was a legacy project that is working towards being compatible with the “strict” option. Furthermore overwriting this option to turn strict on seems to produce errors because some of the code like the config directory is not compatible with strict mode. In my opinion not having this option turned on defeats many of the benefits of TypeScript.

  • Speaking of the config directory, why would these be TypeScript files if they don’t enforce any type? i.e. the admin.ts file is defined as this:
export default ({ env }) => ({
  auth: {
    secret: env('ADMIN_JWT_SECRET')
  apiToken: {
    salt: env('API_TOKEN_SALT')
  transfer: {
    token: {
      salt: env('TRANSFER_TOKEN_SALT')

I don’t see any benefit in this being a TypeScript file. It doesn’t help you define what the object being returned should look like and it doesn’t define what type env is so its treated as the any type.

I haven’t looked through the other directories since this was enough to make me think Strapi doesn’t have very good TypeScript support at the moment. Is this sentiment you guys (the community) also feel is true? As of right now I’m thinking of creating a new project without TypeScript because dealing with half baked TypeScript support feels like its going to be a headache.

strapi is currently working on improving typescript suport

aka they made a typescript generator for entity-service for example

still they are not anywhere neer good enough yet
