Dependency Upgrade

Only upgrade one package at a time.

Upgrade command

npx yarn-update-dependency@latest [package-name]

If the dependency is not defined in any package.json, run the upgrade from the root workspace (the yarn.lock lives there).

Avoid upgrading top-level dependencies (especially test dependencies) without asking the user first.

Ensure updated package.json files end with a newline.

OpenTelemetry constraint

STOP if upgrading any opentelemetry package would introduce forbidden versions:

• 2.x.x (e.g., 2.0.0)
• 0.2xx.x (e.g., 0.200.0, 0.201.0)

Verify before upgrading:

yarn info <package-name>@<version> dependencies

E2E test dependencies

Do not upgrade the major version of a dependency in dev-packages/e2e-tests/test-applications/* if the test directory name pins a version (e.g., nestjs-8 must stay on NestJS 8).

Post-upgrade verification

yarn install
yarn build:dev
yarn dedupe-deps:fix
yarn fix
yarn circularDepCheck
