What it does

Webiny-only. Run all checks required before packages are ready for publish: deps, build, lint, format, tests.

Preflight

Webiny-only skill. Run all checks required before packages are ready for publish.

Important

  • Run steps in order.
  • If any step fails, diagnose and fix the issue, then restart from step 1.
  • Never run tests in parallel. Run each package sequentially.
  • Before running tests for each package, count active test cases and shard at 32 tests per shard.
  • To count active tests: rg "^\s*(it|test|it\.each|test\.each)\s*\(" packages/<name>/__tests__ -t ts --count-matches | awk -F: '{s+=$2} END {print s}'
  • Calculate shards: shards = ceil(count / 32). If shards is 1, no --shard flag needed.
  • Suppress noisy output: redirect stdout to /dev/null or pipe through tail as needed.

Steps

1. Install dependencies

yarn > /dev/null 2>&1

2. Generate webiny package

yarn webiny-scripts generate-webiny-package

3. Sync dependency versions

yarn webiny sync-dependencies

Verify packages/cli/files/duplicates.json is an empty array ([]). If it contains entries, there are duplicate dependency versions that must be resolved before continuing.

4. Generate tsconfig files

node scripts/generateTsConfigsInPackages.js

5. Check package node_modules

node scripts/checkPackageNodeModules.js

6. Verify package.json dependencies match source imports

yarn adio

Must output "All dependencies in order!" to pass.

7. Format code

yarn format:fix > /dev/null 2>&1

This auto-fixes formatting issues. No manual intervention needed.

8. Lint

yarn eslint

This only checks, it does not auto-fix. If eslint reports errors, fix them manually, then restart from step 1.

9. Full clean build

yarn build --no-cache 2>&1 | tail -10

10. Check dist paths

node scripts/checkDistPaths.js

Verifies no src/ paths remain in built output.

11. Run DDB tests
