I just installed this for the MeiliSearch plugin and it's amazingly a single command:
./answer build --with github.com/apache/answer-plugins/search-meilisearch
You have to add more RAM to the app to build anything than the default 256M but it goes out grabs the NodeJS source, compiles it, then slurps it up into the Go binary and dumps out a new_answer.
It even cleans up the build files!
Impressive, and I assume all their plugins are as flawless. So why not enable a few more plugins for everyone?
The next question is can we use MeiliSearch for other apps via this one, since it makes it so easy.
