Add Strict Checks
Goal: Enable stricter TypeScript compiler options and linting to catch bugs that standard TypeScript misses.
Task 1: Add Stricter Compiler Options
Add these additional strict options to tsconfig.json under compilerOptions:
{
"compilerOptions": {
// ... existing options ...
"noImplicitReturns": true,
"noFallthroughCasesInSwitch": true,
"noImplicitOverride": true,
"forceConsistentCasingInFileNames": true,
"exactOptionalPropertyTypes": true,
"useUnknownInCatchVariables": true
}
}
Task 2: Add Check Script
Add a check script to package.json:
{
"scripts": {
"typecheck:app": "tsc --noEmit -p tsconfig.check.json",
"typecheck:tests": "tsc --noEmit -p tsconfig.test.json",
"check": "biome check . && npm run typecheck:app && npm run typecheck:tests"
}
}
Task 3: Fix All Issues
Run npm run check:write && npm run check in a loop, fixing issues until it passes.
IMPORTANT: NEVER disable any checks:
- NEVER disable any biome checks,
- NEVER edit tsconfig.json to remove or disable a check
- NEVER edit tsconfig.check.json to remove or disable a check
- NEVER edit package.json to remove a check from a script
NEVER disable checks, even temporarily for any reason (including for easier work with third-party libraries)
Instead, fix the code to not violate the check.
Task 4: Update CLAUDE.md
Update the "Before Committing" section to include npm run check:
npm test && npm run check
If tests aren't set up yet, just use:
npm run check
Task 5: Commit
Ask the user if they want to commit the changes.
Task 6: Offer Further Hardening
Ask the user: "Would you like to add backend testing as well? This sets up integration tests with an isolated test database."
If yes, follow the add-backend-testing skill.
