Rollup JavaScript API usage example

[slavafomin]

Documentation Is:

• Missing
• Needed
• Confusing
• Not Sure?

Please Explain in Detail...

The JavaScript API usage example looks too simplified. It lacks proper handling of multiple output formats and error handling.

Your Proposal for Changes

I would suggest to update the usage example to something along the lines:

let build: RollupBuild;
let buildFailed = false;

try {

  build = await rollup(input);

  // Generating multiple bundle types
  for (const outputOptions of outputs) {
    await build.write(outputOptions);
  }

} catch (error) {
  errorReporter(error);
  buildFailed = true;

} finally {
  if (build) {
    await build.close();
  }

}

process.exit(buildFailed ? 1 : 0);
