feat: allow passing extra esbuild options for standalone target

[thomasjm]

Per the discussion on #14.

I threw this together in order to get my SSR builds to be minified. We'll probably want to think carefully about the API, because it may involve directly exposing esbuild-specific options. This could cause problems down the road if vike-node wanted to offer alternative bundlers for standalone mode.

It would be cleanest to just pass the appropriate Vite configuration through automatically. However, users who want to minify their SSR builds care about fine-grained control of the minification options, and Vite configuration doesn't provide such; see #14 (comment).

How about standalone: boolean | { esbuild: BuildOptions }?

@brillout I was going to ask you the same thing, so I'll do it that way 👍

@magne4000 Hi, I just tested this and I get this error:

When I look at the at configResolved (file:///root/v3/core-v3/backend/node_modules/vike-node/dist/plugin/index.js:895:7)

It says the issue is here

      assert(typeof configResolvedVike.server.standalone === "boolean");

This is what I passed to the standalone field:

	standalone: {
		esbuild: {
			minify: true,
		},
	},

If I remove it and put true it builds normally.

[magne4000]

Indeed. Let me fix that

Fix released as 0.3.5

@thomasjm I wanted to let you know that vike-node will soon be superseded by vike-server, and with it comes breaking changes, notably regarding how we handle external configuration.

I've released vike-server@1.0.0-beta.2, and here's the migration documentation, and the official documentation.
I'd like to know if some things are breaking, or if you have any kind of feedback.
