Hello, Deno!

TODOs:

• Add preliminary types.
• Add preliminary tests.
• Write documentation.

Looking for feedback.

I think this is ready to be reviewed now, @ry.

One major painpoint, I guess, is that the DOM and JSDOM types are still preliminary. There are also some other future TODOs, for example, investigating whether the bundle size can be improved, testing more of JSDOM's functionality, and rewriting/wrapping some Node specific-parts in JSDOM (for example, JSDOM.fromURL and JSDOM.fromFile both use built-in Node modules). But I think these can be tackled in future PRs.

Another implementation of this that should also work:

export { jsdom as JSDOM } from "./vendor/jsdom.js";
export { jsdom as JSDOM } from "./types/jsdom.ts";

[MarkTiedemann]

Thanks for the suggestion, @j-f1. Unfortunately, this doesn't work on my machine. When I change it, JSDOM can't be imported anymore.

$ deno test.ts
Compile file:///Users/marktiedemann/dev/deno_std/jsdom/mod.ts
error: Uncaught SyntaxError: The requested module './mod.ts' does not provide an export named 'JSDOM'

[j-f1]

Well, that’s unexpected. Sorry to send you on a wild goose chase!

[MarkTiedemann]

No worries, @j-f1.

I just tried again, with the same code, and got a different error:

$ deno test.ts
Compile file:///Users/marktiedemann/dev/deno_std/jsdom/mod.ts

error TS2300: Duplicate identifier 'JSDOM'.

► file:///Users/marktiedemann/dev/deno_std/jsdom/mod.ts:1:19

1 export { jsdom as JSDOM } from "./vendor/jsdom.js";
                    ~~~~~

error TS2300: Duplicate identifier 'JSDOM'.

► file:///Users/marktiedemann/dev/deno_std/jsdom/mod.ts:2:19

2 export { jsdom as JSDOM } from "./types/jsdom.ts";
                    ~~~~~


Found 2 errors.

This seems like a more expected error, still unfortunate.

I suspect denoland/deno#2746 will fix this (or at least make it possible).

[MarkTiedemann]

@kitsonk, awesome! As soon as denoland/deno#2746 is released, I will update the types here.

.d.ts support is in 0.16.

I'm having trouble running the tests with the big bundle file...
