[plugin-webpack] Support multi-entrypoint bundling about create-snowpack-app

[mxmul]

@FredKSchott I'm also trying to use this plugin with 11ty, and would love to see support for multiple HTML entries. I'd be happy to pick this up myself.

What is the execution order of run:* and bundle:*? This relationship does not seem to be documented.

[yuheiy]

If bundle:* is executed after run:* ends, I feel like this plugin would work correctly. After the end of run:*, it should be able to read the fallback file.

https://github.com/pikapkg/create-snowpack-app/blob/6f4e11d3a355c8d72fd80db0483d9faa2d041171/packages/plugin-webpack/plugin.js#L76

[FredKSchott]

We should document that ordering. Currently, all "run" scripts will complete before the "bundle" script/plugin is run.

[FredKSchott]

But again, the issue described in OP is that fallback is not required / may not exist in your project if its not an SPA. The plugin should multiple entrypoints instead /product.html, about.html, etc.

[yuheiy]

Oh, I'm sorry. I misunderstood. In order to target the files generated by 11ty I needed the following settings.

snowpack.config.js:

{
  "scripts": {
    "mount:_site": "mount _output --to /",
    "mount:src": "mount src --to /_dist_",
    "run:11ty": "eleventy",
    "run:11ty::watch": "$1 --watch"
  },
  "plugins": ["@snowpack/plugin-webpack"],
+ "devOptions": {
+   "fallback": "../_output/index.html"
+ }
}

[yuheiy]

It looks like we need to modify snowpack module to allow multiple values for the fallback property. Perhaps, like making the default value from index.html to ['index.html'].

[FredKSchott]

Id rather just add support for the webpack plugin to search for all HTML files in your build directory, and then use those as entrypoints. Right now we're being lazy by just reading from fallback, but that's not really the right use of that config value. The fallback config was just meant for SPAs that wanted it, but all plugins should support the non-SPA use case.

[FredKSchott]

Tackled via #144, released in 1.3.0

Should the readme: https://github.com/pikapkg/create-snowpack-app/tree/master/packages/plugin-webpack#limitations be updated? I guess just add multiple entries to webpack configuration should work?

[FredKSchott]

Bah, my bad, I read the issue title wrong. We now support multiple entrypoints in the HTML file, but not multiple HTML files.

Would still love some help on this one!
