Second.js as well as their inability to process sheer ESM dependencies try the new need I didn’t migrate several of personal Second.js / front end associated packages to sheer ESM. g. vercel/next.js#17806), however they has fixed assistance to own absolute ESM dependencies which had been part of the situation. Properly, You will find moved ahead the past few weeks and you may translated several alot more packages in order to sheer ESM. As time passes, other people does a similar too.

I have got zero sympathy for all of us that have been counting on Jest’s power to transpile resource towards travel and you may fuck to that have inquiries of your runtime from the hacking the imports, in the place of research the real delivery password properly via evaluation that is actually regular JS modules that don’t you need a special system other than just Node.js to operate. It doesn’t matter, for some reason Jest have a tendency to resolve all of the Node.js ESM compat things as it’s an existential material on stability towards the tool, otherwise people is write the assessment.

I might maybe not telephone call cjs depricated. heritage is actually a far more correct word for it. it will more than likely never ever go-away to possess a near future however, the fresh code is to beginning to using esm automatically now.

Out of my very own enjoy we from the node-fetch finger wished to play with transfer and if we wished to possess twin service then it created that individuals will have to transfer what you back again to cjs (even sup dependencies), and that i did not must do any further. We failed to have to copy our code. and now we don’t should reintroduce a beneficial compiler. And we now plus count on most other esm only packages. when we desired to features twin pinalove recenzГ­ support at this stage now this may be meant that we would need to embed all of our sandwich dependencies into node-fetch and transpile them to cjs as well to save an effective very own backup in regards to our worry about, which could content all password and you may categories and hinder circumstances. If someone locations to rely on a comparable style of any of your social classes otherwise sup packages (formdata, heading, blob, document, abortsignal whatwg avenues) or any kind of this may be create just be conflicting having instanceof monitors and you may node-bring will be caught on one inner style of one to plan even if you count on certain latest type.

dual support simply a risk that i want to avoid. cjs aren’t effective in just about any most other env besides NodeJS and NodeJS supports ESM now so why would one want to make use of cjs however? NodeJS is not necessarily the merely platform, developers require its password to the office mix most other env too, even though you situated anything into the cjs that has been solamente built to operate into the NodeJS, then there’ll always be this 1 son that happen to be heading so you can like to that you depending it as ESM to enable them to transfer it without npm otherwise any bundler to possess Deno or perhaps the Browaser.

We agree with your particular typescript affiliate consider they normally use esm while in fact he or she is transpiling in order to cjs without even knowing it

Some body must start converting to absolute ESM at some point. We simply cannot sitt up to and you can loose time waiting for all 23k packages exactly who count on node-bring to alter so you’re able to esm first. Or the almost every other method as much as. We can’t sitt to and you can expect sandwich dependencies or build units to all or any be ESM basic. And then we are unable to handle how gulp, webpack, jest, rollup, typescript, babel, etcetera every manage cjs and you can esm. upcoming we may end up being trapped with cjs/dual packages permanently.

It’s just a chicken therefore the eggs contradiction away from which is to become ESM first. typescript and other have traditionally stick indeed there head on the mud on the extension smaller routes and believe cjs to answer the fresh new street. This can’t keep along these lines whenever we has secluded path resolver which can be vibrant idle brought in
