IN BRIEF:

• Erick Wendel of the Node core team reminds us that Node v20.5 and up support horizontally partitioning/sharding your tests. Essentially you run with

  1	--test-shard

  and pass in the number of shards in total and which shard to run.

• Prettier 3.1, the opinionated code formatter, has been released with support for the new control flow syntax in Angular 17 (released last week) and a new, experimental formatting option for ternary expressions (as in

  1

  x ? y : z

  ).

• Node TSC member Yagiz Nizipli is suggesting using Biome for code formatting since ESLint has deprecated its core formatting rules.

• If you use Amazon SQS, consider updating your AWS SDK to reduce latency – AWS has rolled out a new, more efficient JSON-based protocol.
