stringWorker

The main export of this library is simply a function which returns a worker, running a script provided as a string.

Use with the same caution one would apply to eval.

const worker = stringWorker(`console.log('hello from the worker thread')`)

For relative paths to imported modules, use import.meta.resolve.

const worker = stringWorker(`import '${import.meta.resolve('./example.js')}'`)

As with any worker, remember to terminate it when it's done running.

worker.terminate()

bakeScript

In some cases you may wish to dynamically generate a script for use in a worker. For ease of bundling, it may be beneficial to store that generated script as a string, which can then be ran through stringWorker. The function bakeScript assists in that task.

For example, imagine a script which performs console.log("hello world"). It would need to export a string like this:

export default `console.log("hello world")`

The function bakeScript would generate the text for such a file, including any necessary escape characters.

const script = bakeScript('console.log("hello world")')
// the script can then be saved to a file
await Deno.writeFile("script.js", new TextEncoder().encode(script))

That script's default export can then be imported and ran using stringWorker, and the resulting code can be bundled into one module.

import script from './script.js'
stringWorker(script)
