Hi, @yusukebe @usualoma

What is the reason for fixing the target to node20 in optimize?

For example, there seems to be a difference in the build results when the target is node20 and deno1.

So I think it would be good to default to node20 as the optimized version, but allow the user to specify it using a command line argument ?

Acceptable targets are debatable

• only node and deno LTS version ?
• all node and deno version ?
  • in this case, How do we treat esm and cjs

Image of implementation

Define type OPTIMIZE_TARGET

const OPTIMIZE_TARGETS = ['deno1', 'deno2', 'node20', 'node22', 'node24'] as const
type OPTIMIZE_TARGET = (typeof OPTIMIZE_TARGETS)[number]

Add -t --target option.

    .option('-t, --target [target]', `target platform (${OPTIMIZE_TARGETS.join(', ')})`, (value) => {
        // validation
    })
