About the conference from ASMNEXT · general

The reason why I leave message here is that I decided to hold a small offline conference about WASM at 2 p.m, this Saturday KST/UTC+9 (this Friday 9 p.m./US West, Midnight/US East).

This conference will be held at a conference room called ASSEM, located near Gimpo International Airport in South Korea. (assemhotel.modoo.at)

The conference is for customers and developers interested in WASM in South Korea.

If there is a team interested in this conference, we would appreciate it if you could send us an introduction (video or document or whatever). I will mention the team that sent me the introduction at this conference. Email: wasm@catswords.net

Wasm-bindgen only works in the browser. The webbrowser crate likely uses wasm-bindgen to access the window.open web api. Wasmtime doesn't implement any web api's as it is not a browser. Instead it implements WASI which is closer to a UNIX environment. WASI doesn't have any api for opening a web browser. If you use wasmtime as library rather than executable you could export your own api to open a webbrowser to the wasm module though.

The webbrowser create is to launch the default webbrowser installed on the user system... I'm not trying to run this on a browser, I noticed the difference between wasm-bindgen and wasi.. And following every example I could find it always fails as soon as I try to import any crate...

bjorn3 (Dec 11 2022 at 20:36):

The webbrowser crate doesn't work with wasi. Only native and from within the browser itself. In the later case by using the window.open() javascript api through wasm-bindgen.

bjorn3 (Dec 11 2022 at 20:38):

The difference between wasi and wasm-bindgen is that wasm-bindgen allows binding to browser api's when running inside a browser, while wasi allows using a unix like environment with files, sockets and terminal io when running outside of the browser.
