/storage文件夹中。 But you can decide whether you want to follow a different strategy. Using of plugins you might use the cloud or any sort of database.
- Build a Node.js project on Continous Integration (Bamboo, GitLab, Jenkins, etc) servers is a task that might take several times at a day, thus, the server will download tons of tarballs from the registry every time takes place. As usual, the CI tools clear the cache after each build and the process start over and over again. That is a waste of bandwidth and reduces the external traffic. You can use Verdaccio for caching tarballs and metadata in our internal network and give a boost in your build time.
- Latency and Connectivity, not all countries enjoy a high-speed connection. For such reason cache packages locally in your network is really handy. Either if you are traveling, or have a weak connection, roaming or countries with strong Firewalls that might affect the user experience (eg: corrupting tarballs).
- Offline Mode, all Node Package Managers nowadays uses their own internal cache, but it common that different projects might use different tools, which implies lock files and so on. Those tools are unable to share cache, the unique solution is centralized and relies on a proxy registry, Verdaccio cache all metadata and tarballs are downloaded by demand being able to share them across all your project.
- Avoid that any remote registry suddenly returns HTTP 404 error for tarballs were previously available a.k.a (left-pad issue).
Strategies for faster builds
We are looking for more strategies, feel free to share your experience in this field
Avoid Caching tarballs
If you have a limited storage space, you might need to avoid cache tarballs, enabling
cache false in each uplink will cache only metadata files.
uplinks: npmjs: url: https://registry.npmjs.org/ cache: false
Extending Cache Expiration Time
Verdaccio by default waits 2 minutes to invalidate the cache metadata before fetching new information from the remote registry.
uplinks: npmjs: url: https://registry.npmjs.org/ maxage: 30m
Increasing the value of
maxage in each
uplink remotes will be asked less frequently. This might be a valid strategy if you don't update dependencies so often.
Sometimes caching packages is not a critical step, rather than route packages from different registries and achieving faster build times. There are two plugins that avoid write in a physical hard drive at all using the memory.
npm install -g verdaccio-auth-memory npm install -g verdaccio-memory
The configuration looks like this
auth: auth-memory: users: foo: name: test password: test store: memory: limit: 1000
Remember, once the server is restarted the data is being lost, we recommend this setup in cases where you do not need to persist at all.
