Cargo.lock for dioxus-cli is outdates

[uzytkownik]

Problem

Some packaging tools like nix use Cargo.lock to pick up versions of the dependencies. Currently dioxus-cli Cargo.lock uses 0.2.93 webasm-bindgen but rest of Dioxus uses 0.2.95 version of bindgen.

Steps To Reproduce

Steps to reproduce the behavior:

• Use packager using Cargo.lock
• Create example
• Run dx serve

Expected behavior

Sample application runs

Actual behaviour

dx fails due to mismatch of versions

Environment:

• Dioxus version: 0.5.7
• Rust version: 1.80.0
• OS info: Nix
• App platform: all

I can reproduce this as well on my machine

flake.nix

{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";
    flake-utils.url = "github:numtide/flake-utils";
  };

  outputs =
    {
      self,
      nixpkgs,
      flake-utils,
    }:
    flake-utils.lib.eachDefaultSystem (
      system:
      let
        pkgs = import nixpkgs { inherit system; };
      in
      {
        devShell =
          with pkgs;
          mkShell {
            buildInputs = [

called `Result::unwrap()` on an `Err` value: 

it looks like the Rust project used to create this wasm file was linked against
version of wasm-bindgen that uses a different bindgen format than this binary:

  rust wasm file schema version: 0.2.95
     this binary schema version: 0.2.93

Currently the bindgen format is unstable enough that these two schema versions
must exactly match. You can accomplish this by either updating this binary or
the wasm-bindgen dependency in the Rust project.

You should be able to update the wasm-bindgen dependency with:

    cargo update -p wasm-bindgen --precise 0.2.93

don't forget to recompile your wasm file! Alternatively, you can update the
binary with:

    cargo install -f wasm-bindgen-cli --version 0.2.95

if this warning fails to go away though and you're not sure what to do feel free
to open an issue at https://github.com/rustwasm/wasm-bindgen/issues!

    This is probably due to the Bindgen version, dioxus-cli is using `0.2.93` which is not compatible wi
th your crate.
    Please reinstall the dioxus cli to fix this issue.
    You can reinstall the dioxus cli by running `cargo install dioxus-cli --force` and then rebuild your
 project

[mikedilger]

I had this on ArchLinux but running cargo install --force dioxus-cli rebuilt it and it no longer complains about the 0.2.93 and 0.2.95 mismatch.

[RusticCraftsman]

Found the exact same problem on my nixos system, haven't found any declarative solutions yet

[ealmloff]

We keep the wasm bindgen version unlocked so that it updates to match other dependencies in the ecosystem that pull in the latest version of wasm bindgen like web-sys. You can fix this issue by reinstalling the CLI with cargo install --force dioxus-cli (without --locked)

It should be added that you also have to add $HOME/.cargo/bin to path

It seems that dioxus-cli v0.6.1 introduces a mechanism of auto downloading the correct version of wasm-bindgen, but I couldn't make it work no matter how. I even tried manually downloading wasm-bindgen binaries and putting them into ~/.local/share/dioxus/wasm-bindgen/ (btw the directory was present but empty before), but the dx serve command still produces the following:

20:52:42 [dev] Build completed successfully - output location: "/home/j4ger/Documents/pele/tmp/target/server-dev/tmp"

Caused by:

1: No such file or directory (os error 2))

Also, I'm curious if someone is able to setup a full flake-based devShell for dioxus, as all the solutions available now seem to be reliant on cargo install.

i have been using this and upgrading it forever with also using direnv:

export WEBKIT_DISABLE_COMPOSITING_MODE=1
export PATH=$HOME/.cargo/bin:$PATH
# export OPENSSL_DIR=$(dirname $(whereis openssl | awk '{print $2}')) # doesn't work since openssl binary path is not the same as the one required
use flake

i should later integrate these exports into my flake

I hope this helps someone find a way to make it fully work without the need for manually having to use cargo or just make its life easier for using dioxus.

Thank you for this, I need to fix our nix flake but am/was unsure how to go about it.

[j4ger]

After digging into the source of dioxus cli I found out the reason why dx skipped installing the proper wasm-bindgen: the trigger for installing wasm-bindgen comes after the logic of toolchain verification, as my nix devShell does not rely on rustup, the verification function bails out in the middle, thus skipping the download. After adding rustup to the devShell all problems were gone. I'll try to come up with a simplified flake.nix and maybe create a pull request shortly after.

Also, just for the clarification, the current flake.nix in the repo only creates a devShell for developing dioxus itself, but I don't think it's meant for developers using dioxus as a framework, as it does not setup dx and other toolchain for you. I hope I can come up with a proper solution for this.

Would there be any way of doing this without the use of rustup? it is not best for usage in flakes

I've created a PR here: #3442

While it is under review, you can tryout my fork first. I made a mockup rustup script to bypass the verification and it works for now.

Although the "nix-way" to do this would be to include a build of wasm-bindgen in the flake as well so that all artifacts used are deterministic, I can't come up with a better way to do so other than mangling with the $XDG_STATE_HOME envvars. As it would create potential issues for library users, I left that part unchanged and rely on dx's own installation process.
