Some packages missing from snowpack build

[rmorshea]

I have explicitly configured all the packages I want to appear in the build within the snowpack.install list. When using snowpack install all the listed packages get populated in ./web_modules as expected. However when I try using snowpack build the ./build/web_modules only includes the dependencies which I assume snowpack's import finder was able to discover.

For example if my code only imports package a and my config looks a bit like this:

{
  "snowpack": {
    "install": ["a", "b"]
  }
}

The snowpack install command will produce:

./web_modules
  - a.js
  - b.js

But the snowpack build command will produce:

./build/web_modules
  - a.js

How do I force snowpack build to include all the same packages that snowpack install does?

Further Findings

• This actually looks like a regression that was introduced in 2.13. Prior to this version I'm able to get everything to work as expected by running snowpack && snowpack build

I've noticed this as well. Is the npm depdency b imported in a file? From what I recall, if it is not, the snowpack build command will not include it, as it scans your application files for node deps. If I'm not mistaken, the snowpack install command does not do such an in-depth scan and goes by what is included in:

{
  "snowpack": {
    "install": ["a", "b"]
  }
}

@FredKSchott or @drwpow will need to confirm this though.

@FredKSchott any movement on this?

@FredKSchott any updates on this issue?

[FredKSchott]

Yes! Check out #2707 and try running there, it installs packages at runtime if it can't detect them at start time. Would love your feedback if it works/doesn't

[rmorshea]

Awesome! Not sure when I'll have time to try upgrading, but will post back here once I do.

@FredKSchott I'm not seeing any change in behavior with respect to this issue. Unfortunately dynamically imported packages are still excluded from the build even if they are explicitly specified in knownEntrypoints so I've got to stick with <2.13 for now.
