Looking at:

https://github.com/opensearch-project/OpenSearch-Dashboards/tree/main/packages

Downloading this repo could take a while depending on how good the machine.

There are a lot of files. A lot of these files we haven't touched in years, these packages are stabilized but need to be built every time in a release and then installed as a node modules.

Builds take longer as the build pipeline has to download such a heavy repo and build all the packages initially. So that it can bootstrap the plugins properly.

Describe the solution you'd like

We should audit packages that have not been touched in while.

The project has an account: https://www.npmjs.com/package/@opensearch-project/opensearch

We can create individual packages for these or we can consider adding it to a single package that contains these dependencies. Kind of like a SDK: https://www.npmjs.com/package/@avillk/opensearch-dashboards-sdk. Regardless, we should consider adding the stable packages outside of this repo.

Describe alternatives you've considered

Available in GitHub? For example, https://github.com/opensearch-project/opensearch-dashboards-functional-test/blob/main/package.json#L51
