## Report
|
||||
|
||||
* Upon doing research on helia, we found that some of the methods on implementing JavaScript on Rust with callback and using yew have problems with the
|
||||
imports of Helia.
|
||||
The following are issues found with the different methods:
|
||||
1. With web-pack: While trying to import Helia's libraries on a previosly working app using callback to implement JavaScript on a yew template, we
|
||||
stumbled upon an error in which we couldn't install the Helia library due to there being too many packages.
|
||||
Possible solutions implemented:
|
||||
- Importing Helia from the import link instead of installing the library, though one of the problems with this solution is that you can't do imports
|
||||
and at the same time export a function with the JS callback on Rust. It was necessary to first import the Helia library and then use it for the export function.
|
||||
- Adding the import links to the index.html like script modules.
|
||||
|
||||
2. After not finding a concrete solution that would help us with the import, I decided to follow the yew tutorial drive through libraries that was very well
|
||||
documented but a little outdated since it was using yew version 12. Now the problem was the it had two errors that wouldn't let me run the app.
|
||||
Specific errors found:
|
||||
* error [E0433]: failed to resolve: unresolved import (a function from the wasm-bindgen.rs that comes from the version of wasm-bindgen that you installed).
|
||||
* error [E0425]: cannot find the function 'wasm_bindgen_initialized' in this scope (also coming from wasm-bindgen.rs).
|
||||
|
||||
|
||||
Possible solutions implemented:
|
||||
|
||||
- Updating to the newest version of wasm_bindgen.
|
||||
- Trying to change the imports of wasm_bindgen.
|
||||
- Adding the dependency to de Cargo.toml file.
|
||||
> None of these solutions worked
|
||||
|
||||
3. Currently using the yew-interop to asynchronously Load CSS or Javascript libraries which allows you to import libraries from links and also implements
|
||||
JavaScript scripts to Rust.
|
||||
Using the example provided in the examples GitHub repository to know how to have the correct structure and succesfully import everything necessary for the app.
