migrate

Creates a migrations file or runs migrations from the migrations file.

  • Migrate packages and create migrations.json (e.g., nx migrate @nx/workspace@latest)
  • Run migrations (e.g., nx migrate --run-migrations=migrations.json). Use flag --if-exists to run migrations only if the migrations file exists.

Usage

โฏ

nx migrate [packageAndVersion]

Install nx globally to invoke the command directly using nx, or use npx nx, yarn nx, or pnpm nx.

Examples

Update all Nx plugins to "latest". This will generate migrations.json:

โฏ

nx migrate latest

Update all Nx plugins to "9.0.0". This will generate migrations.json:

โฏ

nx migrate 9.0.0

Update @nx/workspace and generate the list of migrations starting with version 8.0.0 of @nx/workspace and @nx/node, regardless of what is installed locally:

โฏ

nx migrate @nx/workspace@9.0.0 --from="@nx/workspace@8.0.0,@nx/node@8.0.0"

Update @nx/workspace to "9.0.0". If it tries to update @nx/react or @nx/angular, use version "9.0.1":

โฏ

nx migrate @nx/workspace@9.0.0 --to="@nx/react@9.0.1,@nx/angular@9.0.1"

Update another-package to "12.0.0". This will update other packages and will generate migrations.json file:

โฏ

nx migrate another-package@12.0.0

Collect package updates and migrations in interactive mode. In this mode, the user will be prompted whether to apply any optional package update and migration:

โฏ

nx migrate latest --interactive
