Question

A development team runs a CodeBuild project as part of a CodePipeline. Each build downloads hundreds of Node.js dependencies from the internet, taking several minutes and increasing build costs. The dependencies rarely change between builds. Which change will MOST reduce build duration with the least ongoing maintenance effort?

Accepted Answer

Enable local caching or Amazon S3 caching in the CodeBuild project and reference the dependency directory as a cache path in the buildspec.

Answer

Increase the CodeBuild compute type to a larger instance so downloads complete faster in parallel.

Answer

Add a manual approval action in CodePipeline before the build stage so dependencies can be pre-installed by an engineer.

Answer

Move the CodeBuild project into a VPC with a NAT gateway to accelerate outbound internet traffic.
