Change and check

Lesson 2 of 3 in Ship a first pull request. About 20 minutes.

In this lesson you make the change, run the checks and save your work.

Steps

Make the change. One concern per pull request. If your change alters a command, a setting, a route or a setup step, edit the docs page that states it in the same pull request.
Run the checks for the part you touched.
- You changed backend/:
  Terminal window
```
dotnet test tests/TextStack.UnitTests
dotnet format textstack.sln --verify-no-changes
```
- You changed apps/web/:
  Terminal window
```
pnpm -C apps/web test
pnpm -C apps/web build
```
- You changed apps/admin/:
  Terminal window
```
pnpm -C apps/admin build
```
- You changed apps/mobile/:
  Terminal window
```
pnpm --filter mobile typecheck
```
- You changed docs/ or any .md file:
  Terminal window
```
node scripts/check-doc-links.mjs
```
You should see: every command ends without errors. The backend unit tests print Passed! with zero failed.
Commit. One logical change per commit. The first line is type(scope): summary. The types are feat, fix, refactor, docs and test.
Terminal window
```
git add -A
git commit -m "fix(reader): keep the position after a font change"
```

dotnet format reports changes. Run dotnet format textstack.sln without --verify-no-changes, then commit the result.
dotnet test with no project name fails with connection errors. It also runs the integration tests, which need the running backend. Run the unit test project only. CI runs the rest.
