The npm registry will upgrade its public CouchDB instance on September 15, 2021. As part of this upgrade, we will promote a new CouchDB replica to become our new public CouchDB instance, https://replicate.npmjs.com. This upgrade will reset the CouchDB sequence number.
If you are not familiar with CouchDB replication, then you will not be impacted by this change. In particular, users running npm install
or running other commands using the npm
CLI will not be affected by this change.
If you replicate our public CouchDB or have an application that is following it, then you may be impacted:
-
If you are replicating the npm database using CouchDB then you may see a replication delay while your follower re-synchronizes, but you do not need to take any other action.
-
If you have custom tools that query npm's databases using the CouchDB Replication Protocol then you should ensure that you do not assume that sequence numbers are monotonically increasing, and that your custom replica correctly treats the sequence number as an opaque blob.
