npx jsr add @fmt/yamlfmt

await init();

const input = "- a\n- b\n";

const formatted = format(input, "sample.yaml");
console.log(formatted);

For Vite users:

Add "@wasm-fmt/yamlfmt" to optimizeDeps.exclude in your vite config:

{
    "optimizeDeps": {
        "exclude": ["@wasm-fmt/yamlfmt"]
    }
}

If you cannot change the vite config, you can use another import entry

import init, { format } from "@wasm-fmt/yamlfmt/vite";

// ...
