I've been using the node cache feature for some time now and have been using yarn to load my load modules with the following pipeline snippet:
- yarn install
Observing the performance over several pipelines I haven't noticed any reduction in load time. I'm aware that the cache may not trigger for every pipeline, but I wanted to know if using yarn instead of npm is currently supported or is planned to be supported by pipelines caching.
I can't reply for Shane, but I am following the same process outlined in the doc you linked to, but am not seeing any benefits either. I believe I used to before but it's been a while since I noticed no benefits. At this time, my `yarn install`s take over half a minute despite the cache.
Incidentally, at the bottom I see `Cache "node": Skipping upload for previously downloaded cache`
I think these answers are missing the point.
This isn't about Bitbucket caching the yarn installation... it's about caching the modules that yarn installs... the dependencies of the project being built.
I routinely see my `yarn install`s taking ~3m... they should take less than a second if my node_modules directory was being cached properly
After playing around a bit, I've found that the following currently works
pipelines: default: - step: name: Build image: node:6.11.4 caches: - yarncustom script: - curl -o- -L https://yarnpkg.com/install.sh | bash -s -- --version 1.3.2 - export PATH=$HOME/.yarn/bin:$PATH - yarn - yarn build definitions: caches: yarncustom: /usr/local/share/.cache/yarn/v1
I got here by executing "yarn cache dir" on a Bitbucket Pipeline and then just setup a custom cache as per the documentation. I then executed my build subsequent times with "yarn --verbose". I was able to confirm that builds were using the cache by seeing if it needed to download the modules again.
@Jake Ben Thanks that worked for me too and double checked like you did. The cache download time is almost as slow as pulling from yarn but still a little boost.
Another point, the node docker image contains yarn so don't think there's a reason to install it via curl.. unless I'm missing something.
