This is the best argument for string directives I have seen.

I still wish we had a better way to tell developers and computers that this code runs differently than "normal" JavaScript. String directives seem like the best way we have.

Great work @danabra.mov

aargh someone kill me. literally THE WHOLE POINT of directives is that they’re not just strings!

they’re syntactically attached to the scope (function or module) in a way that’s reflected in AST.

and both RSC and Next.js ones act at module boundary which is kinda gross for decorators or API calls

This event also led to various discussions in the community, following the introduction of parametrized directives (’use cache: private’ / ’use cache: remote’), and the introduction of a Vercel ’use workflow’ directive the next day. Many developers argue it’s dangerous to use strings and would prefer function decorators or explicit typesafe API calls. We still need to think about it before making up our minds and taking a side, but here are some related links worth checking out:

In the latest version of @rolldown.rs, JSON imports are tree-shaken!

No more superfluous JSON values in your bundle, only these that you actually access. Without any change of code or config ✨

Interested in the code? Then check out the PR! github.com/rolldown/rol...

$First column - title "input". A config.json file with content: { "apiUrl": "https://api.example.com/", "timeout": 5000, "retries": 3, "debug": false } Then an index.js file with the content: import config from './config.json'; console.log(config.apiUrl); Under it the text "Import JSON as usual". Second column - "before". An index.js file that is bundled, with content: //#region config.json var apiUrl = "https://api.example.com/"; var timeout = 5e3; var retries = 3; var debug = false; var config_default = { apiUrl, timeout, retries, debug }; //#endregion //#region index.js console.log(config_default.apiUrl); //#endregion Under it the text "The whole JSON is bundled". Third column - title "after". An index.js file (output) that is bundled, with the following content: //#region config.json var apiUrl = "https://api.example.com/"; //#endregion //#region index.js console.log(apiUrl); //#endregion Under it the text "Only necessary JSON values are included".$

Off to React conf...looking forward to seeing how React is innovating with the boring stuff like scheduling, compilers, performance, caching, and cross compatibility.

My first reaction is that I like this, and it solves my main annoyances with JSX being a "weird" subset of JS while not having loops,if statements, function calls, and variables.

It looks similar to Angular's new control flow syntax, so I wonder if there are some good learning from Angular.
