ng-update
update Angular packages and run automatic migrations
TLDR
SYNOPSIS
ng update [packages...] [options]
DESCRIPTION
ng update updates Angular packages and dependencies to a newer version and runs schematics that migrate application code for breaking changes. It is part of the Angular CLI.Running ng update without arguments prints a list of installed packages that have newer versions available, along with the suggested update command. With one or more package names, it performs the update and executes any associated migration schematics.The command refuses to run by default if the repository has uncommitted changes; pass --allow-dirty to override, or commit/stash first.
PARAMETERS
--allow-dirty
Permit updates when the working tree has modified or untracked files (default: false).-C, --create-commits
Create source-control commits for each update and migration step (default: false).--force
Bypass peer dependency version mismatches (default: false).--from version
Version to migrate from. Only valid with a single package and --migrate-only.--to version
Target version for migrations. Requires --from and --migrate-only; defaults to the detected installed version.--migrate-only
Run migration schematics only, without changing installed versions.--name name
Specify a particular migration to run. Only valid for a single package update.--next
Use prerelease versions (beta / release candidate) when resolving the target version.--verbose
Show additional execution details.--help
Print help.
CAVEATS
Always commit or stash work in progress before running ng update; running with --allow-dirty --force can leave the repository in a hard-to-recover state. Migrations are written and tested for one minor version step at a time, so jumping multiple major versions in a single command is unsupported: update one major version at a time.
HISTORY
ng update was introduced with the Angular CLI 6 rewrite in 2018, replacing the previous manual update workflow. It is part of the schematics-based tooling that powers Angular's automated migration story.
