Bundler
Bundle TypeScript and JavaScript code, along with their dependencies, into a single file. Useful for producing self-contained scripts for distribution or deployment.
Eg Deno.bundle
function Deno.bundle
bundle(options: Deno.bundle.Options): Promise<Deno.bundle.Result>Bundle Typescript/Javascript code into a single file.
This is an unstable API and requires the --unstable-bundle flag to be passed when running Deno:
deno run --unstable-bundle main.ts
const result = await Deno.bundle({
entrypoints: ["./main.ts"],
minify: true,
});
for (const file of result.outputFiles ?? []) {
console.log(file.text());
}
Requires read access to local entrypoints and their dependency trees, import access to remote modules, and write access when output is written to the filesystem.
