v3.15.2

Patch Changes

• Jest.mergePreset: Do not mutate underlying defaults (#595)

  Jest.mergePreset no longer mutates the internal jest-preset object. Subsequent calls to Jest.mergePreset will no longer return results merged in from previous calls.

  Warning: If you rely on mutating the core jest-preset object for later access, this is a Breaking Change.

• template/lambda-sqs-worker: Convert Serverless isProduction config value to boolean (#602)

  This avoids potentially surprising behaviour if you try to make use of this config value in a context that tests for truthiness. The boolean is still correctly applied as a string seek:env:production tag value.

• node, start: Handle void function inputs and outputs (#597)

  When running a function entrypoint, skuba node and skuba start now handle an omitted request body the same as an empty JSON array of arguments []. The function can also return undefined to omit a response body.

• template/lambda-sqs-worker: Opt in to new Serverless variables resolver (#601)

• lint: Use worker threads when running --serially (#607)

  This aims to reduce the memory footprint of skuba lint --serial. ESLint and Prettier are now run in worker threads so their memory can be more readily freed on thread exit.

• template: Remove README tables of contents (#596)

  GitHub's Markdown renderer now generates its own table of contents.

• configure, init: Drop dependency on external Git installation (#599)

  We now interface with isomorphic-git internally, which ensures compatibility and affords finer control over log output.

• format, lint: Run Prettier serially on files (#606)

  This aims to reduce the memory footprint of skuba lint.

• template: seek-jobs/gantry v1.5.1 (#604)

• Jest.mergePreset: Allow configuration of test environment (#592)

  Jest's testEnvironment can now be passed to Jest.mergePreset:

  export default Jest.mergePreset({
    testEnvironment: 'jsdom',
  });

• template/lambda-sqs-worker: Fail fast on invalid Serverless config (#605)

• template: pino-pretty ^6.0.0 (#594)

  pino-pretty@7 requires pino@7, which has not been released on its stable channel yet.

• node, start: Print function entrypoint parameters (#600)

  When running a function entrypoint, skuba node and skuba start now print the function and parameter names as a usage hint:

  yarn skuba node 'src/api/buildkite/annotate.ts#annotate'
  // annotate (markdown, opts)
  // listening on port 9001
  
  curl --data '["_Hello there_", {}]' --include localhost:9001
