Typescript / CJS / MJS Just in time compilation support

[stafyniaksacha]

What does it do?

These changes allow loading .cjs, .mjs and .ts files for any part of strapi server without any extra configuration for the client:

• apis (routes/controllers/services/contentTypes)
• middlewares
• policies
• extensions
• plugins
• configurations files

I've used jiti which describe itself to be a "Runtime typescript and ESM support for Node.js (CommonJS)"

Why is it needed?

This allows developers to use typescript in their application or plugins

How to test it?

I have made a working template https://github.com/stafyniaksacha/strapi-typescript-sample

git clone git@github.com:stafyniaksacha/strapi-typescript-sample.git
cd strapi-typescript-sample
yarn
yarn develop # or yarn start

What does it do not?

This PR does not aim to provide strapi core types, but only to add the ability to use strapi with typescript and ESM modules

Hi @stafyniaksacha thanks for the work ! We are soon going to start working on typescript support and this will probably help us a lot 💯

@alexandrebodin that's great to hear! When do you think typescript support will be available?

[nghiepdev]

Hey, Can tell me which future release version will support Typescript? 5.0 or 4.2.

[stafyniaksacha]

5.0 or 4.2

@nghiepit Never heard about Typescript 5.x, what will changes ? Typescript has adopted a non-breaking release cycle through, so things should continue to work on later version.

I think the question was referring to Strapi's version :) it is planned to be part of the v4 not v5 of Strapi

@alexandrebodin / @Convly due to what is currently being worked on should we close this (no offence to you @stafyniaksacha, we have discussed in private ;) )
