List of supported browsers?

[patricklafrance]

I am implementing a function to convert browserslist results to SWC targets, similar to https://github.com/marcofugaro/browserslist-to-esbuild/tree/main. I keep getting error messages like the following:

thread '<unnamed>' panicked at 'not implemented: Targets: {"bb": Query(Single("7")), "ie": Query(Single("5.5")), "edge": Query(Single("106")), "firefox": Query(Single("107")), "opera": Query(Single("92")), "android": Query(Single("115")), "chrome": Query(Single("107")), "samsung": Query(Single("12")), "safari": Query(Single("15.2"))}', C:\Users\runneradmin\.cargo\registry\src\index.crates.io-6f17d22bba15001f\preset_env_base-0.4.5\src\query.rs:124:13
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
assets by status 1.1 KiB [cached] 2 assets
./src/index.ts 39 bytes [built] [code generated] [1 error]

I get these error messages from SWC but from my understanding SWC is delegating this to browserslist-rs.

I was wondering what targets does browserlist-rs support?

For example, "baidu", "kaios" and "bb" seems to be supported by the original browserslist tool but not by browserlist-rs.

Thank you!

Look at this function:

browserslist-rs/build.rs

Line 10 in 99a3244

fn encode_browser_name(name: &str) -> u8 {

Thank you for the quick answer, appreciated 🙏🏻

I hope it's fine if I ask here @g-plane, instead of on the SWC repository. I noticed that you are a contributor to both projects.

Do you have any idea why when I provide a target to SWC for any of the following browsers: "ios_saf", "op_mini", "bb", "ie_mob", "and_uc", "and_qq", "baidu", "kaios", I get an error similar to this?

ERROR in ./src/index.ts
Module build failed (from ./node_modules/.pnpm/swc-loader@0.2.3_@swc+core@1.3.78_webpack@5.88.2/node_modules/swc-loader/src/index.js):
Error: failed to handle: not implemented: Targets: {"samsung": Query(Single("12")), "edge": Query(Single("106")), "kaios": Query(Single("2.5")), "and_qq": Query(Single("13.1")), "ie_mob": Query(Single("10")), "op_mob": Query(Single("73")), "chrome": Query(Single("107")), "safari": Query(Single("15.2")), "opera": Query(Single("92")), "and_ff": Query(Single("115")), "and_uc": Query(Single("15.5")), "ie": Query(Single("5.5")), "and_chr": Query(Single("115")), "baidu": Query(Single("13.18")), "bb": Query(Single("7")), "firefox": Query(Single("107")), "ios_saf": Query(Single("15.2")), "android": Query(Single("115")), "op_mini": Query(Single("all"))}

According to this list: browserslist-rs/build.rs, they are all supported by browserslist-rs.

The following env.targets result in the previous error:

{
   env: {
      targets: {
        and_chr: '115',
        and_ff: '115',
        and_qq: '13.1',
        and_uc: '15.5',
        android: '115',
        baidu: '13.18',
        bb: '7',
        chrome: '107',
        edge: '106',
        firefox: '107',
        ie: '5.5',
        ie_mob: '10',
        ios_saf: '15.2',
        kaios: '2.5',
        op_mini: 'all',
        op_mob: '73',
        opera: '92',
        safari: '15.2',
        samsung: '12'
     }
   }
}

While the following is fine:

{
   env: {
      targets: {
         and_chr: '115',
         and_ff: '115',
         android: '115',
         chrome: '107',
         edge: '106',
         firefox: '107',
         ie: '5.5',
         op_mob: '73',
         opera: '92',
         safari: '15.2',
         samsung: '12'
      }
   }
}

Thank you,

If you've installed Rust development environment, you can clone this repository and check your query with the command below:

cargo run --example inspect -- <query>

If it outputs result successfully, it means "browserslist-rs" works, then you need to consult SWC because they do additional transformations.
