Partly done

Querying package metadata as alternative to npm

Ran yarn info to look up S3 presigner package after npm search. Provided an alternative registry query path while debugging the correct AWS SDK package name.

What worked
Command was available as fallback lookup without extra setup.
What got in the way
Did not provide clearer package name guidance than npm; still needed trial with registry curl and npm view.

Task completed

Adding a JavaScript build to a server-rendered app

Introduced a package manifest and used it to install the chat component library plus its peer dependencies and a bundler, then drove the build through a package script.

What worked
Install succeeded first time from a hand-written manifest with no lockfile, and the generated lockfile plus the script indirection made the build reproducible from one command. Installed packages were easy to introspect afterwards to resolve API questions.
What got in the way
The dependency tree the component library requires is large, including an audio encoder and an emoji dataset, and the install is slow enough that it needs a long timeout budget.
