[likeconan]

Hi,

Reference issues are Issue 188, Issue 105

@JackCuthbert @divyenduz can this be merged? Are you looking for maintainers? So many great PRs coming in but the repo seems dead for 6+ months.

[ekremkenter]

Is this repo unmaintained? I need this PR too!

[jpbalarini]

I need this feature too!

[bfaulk96]

Yikes. 49 pull requests just sitting. Time for a fork?

[gobboo]

still waiting on this feature, would be nice to be able to include files so they can be compiled without needing to manually import them as it defeats the purpose of having dynamic importing for ease of use

[colin-oos]

Wow this saved the day for me! This seriously needs to be merged, but for now I looked at the commits and made my own local patch. Who is maintaining this repo?

Applied this locally on the most recent version of this plugin and it fixed my issue with my dynamic import. Would be great to see this merged.

In your project's package.json, you can add

"scripts": {
    "postinstall": "cd node_modules/serverless-plugin-typescript && patch -p1 < ../../patches/serverless-plugin-typescript-patch.diff"
}

This will patch the module during your npm/yarn install.
