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

Run

yarn test

for each package below, sequentially. Count active tests first and shard at 32.

Packages that need

yarn test

```
api
```
```
api-aco
```
```
api-audit-logs
```
```
api-core
```
```

```
```

# 1. Count active tests
count=$(rg "^\s*(it|test|it\.each|test\.each)\s*\(" packages/<name>/__tests__ -t ts --count-matches | awk -F: '{s+=$2} END {print s}')
shards=$(( (count + 31) / 32 ))

# 2a. If shards <= 1, run without sharding
yarn test packages/<name> 2>&1 | grep "Test Files"

# 2b. If shards > 1, run each shard sequentially
yarn test packages/<name> --shard=1/$shards 2>&1 | grep "Test Files"
yarn test packages/<name> --shard=2/$shards 2>&1 | grep "Test Files"
# ... etc

12. Run OpenSearch tests

Run

yarn test:os

for each package below, sequentially. Count active tests first and shard at 32.

Packages that need BOTH

yarn test

(step 11) AND
yarn test:os
:

```
api-aco
```
```
api-audit-logs
```
```
api-file-manager
```
```
api-file-manager-aco
```
```
api-headless-cms
```
```
api-headless-cms-aco
```
```
api-headless-cms-bulk-actions
```
```
api-headless-cms-import-export
```
```
api-mailer
```
```
api-scheduler
```
```
api-workflows
```
```
tasks
```

Packages that need ONLY

yarn test:os

(not in step 11):

```
api-dynamodb-to-elasticsearch
```
```
api-elasticsearch-tasks
```
```
api-headless-cms-ddb-es
```
```
api-headless-cms-es-tasks
```
```
api-opensearch
```

yarn test:os packages/<name> 2>&1 | grep "Test Files"

13. Check for uncommitted changes

git status

Report any unexpected uncommitted changes from the steps above.

Keeping the package lists up to date

If the lists seem stale, re-derive them:

# All testable packages (have vitest.config.ts)
find packages -maxdepth 2 -name "vitest.config.ts" | sed 's|packages/||;s|/vitest.config.ts||' | sort

# Packages with ddb-os support
grep -rl "ddb-os" --include="ci.config.json" packages/ | sed 's|packages/||;s|/ci.config.json||' | sort

# Check if a package has standalone ddb tests too
grep -o '"ddb"' packages/<name>/ci.config.json
