Angular 14

Angular 14 added strictly typed reactive forms, so FormControl, FormGroup, and FormArray can carry value types through form code instead of relying on broad any-based APIs. It introduced the standalone component, directive, and pipe APIs as a developer preview, offering an alternative to declaring every UI building block in an NgModule. It also expanded dependency injection with the inject function, enabling injection in supported injection contexts outside the traditional constructor-parameter pattern, and improved Angular CLI tooling, including shell command completion. These changes built on the established NgModule-based Angular model rather than removing it; standalone APIs were not yet the settled migration target they became in later Angular releases. Angular is not AngularJS: AngularJS is a separate, earlier framework with its own versions and its own end of life. Teams running AngularJS should use /technology/angularjs instead.

Angular 14 has reached end of life, so teams remaining on it do not receive upstream fixes, security updates, or compatibility work for that release line. The practical exposure grows as browsers, Node.js, TypeScript, package managers, test tools, and third-party Angular libraries move beyond the versions Angular 14 was designed to support. Dependency updates can become constrained by Angular 14's compiler and tooling requirements, while holding dependencies back can leave known vulnerabilities or operational defects unresolved. A delayed upgrade also makes the eventual move harder: a team must cross more framework migrations at once, resolve accumulated deprecations, and verify application behavior against changes in the compiler, build system, router, forms, and component libraries. Projects that adopted Angular 14's standalone APIs while they were still in preview should give those areas particular review during migration, because later Angular versions refined that model.

Plan an upgrade to a currently supported Angular release, using Angular's official update guidance for each required major-version step rather than attempting to skip validation across several changes. First inventory the application, Angular CLI, Angular Material or CDK, custom builders, test runner, TypeScript, Node.js runtime, and all Angular-dependent libraries; identify their supported version ranges before changing the framework. Upgrade in a branch with reproducible builds and a full automated test suite, then run production builds, unit and integration tests, browser checks, server-side rendering checks where applicable, and accessibility and visual regression tests for component-library changes. Address compiler warnings and deprecated APIs as part of the migration instead of suppressing them. Review reactive forms for typed-form assumptions and review any early standalone-component usage against the current documented APIs. Finally, update CI images, lockfiles, deployment runtimes, and monitoring dependencies so production uses the same supported toolchain that was validated during the upgrade.
