Actually, a modified version that we made based on a reverse-engineered version of the original at https://unlimited.waifu2x.net.
Use a TypeScript IDE like WebStorm.
No double-quoted strings, use tabs for indentation, don't use jquery.
Right-click tsconfig.json and choose Compile TypeScript.
You can configure it to recompile automatically by opening Settings and enabling
Languages & Frameworks > TypeScript > TypeScript language service >
Recompile on changes.
You can run tsc with no arguments to create script.js and script.js.map.
It might eventually be possible to use esbuild if you don't want to install
npm (for tsc) or WebStorm (expensive), but as of this writing, esbuild
doesn't support this type of
project yet, and we're not willing to break compatibility with tsc.
This project won't work over the file:// protocol, you have to use a local
HTTP server. This is because:
- Fetch requests can't be made to
file://URLs, so ORT can't load its WASM (even if it could, it wouldn't be able to download the model files anyway) - Web Workers can't be created from
file://URLs, so the models can't run - Some extra HTTP headers need to be sent for multithreading to work
ORT supports parallel model execution, which can make waifu2x much faster. But
browsers only allow the use of SharedArrayBuffer if some extra HTTP headers
are sent by the server:
Cross-Origin-Embedder-Policy: require-corpCross-Origin-Opener-Policy: same-origin
Without them, multithreading won't work.
miniserve . --index index.html --header 'Cross-Origin-Embedder-Policy: require-corp' --header 'Cross-Origin-Opener-Policy: same-origin'
esbuild can run in "serve" mode, which exposes a local HTTP server that
automatically rebuilds the project on reload. Unfortunately, esbuild
doesn't support this type of
project yet, and we're not willing to break compatibility with tsc.
