Previously we didn't clarify that the stricter defaults have no impact on existing projects, and we also didn't define the default values for bundle budgets. Fixes #41966 PR Close #42289

Strict mode
Angular CLI creates all new workspaces and projects with strict mode enabled.
Strict mode improves maintainability and helps you catch bugs ahead of time.
Additionally, strict mode applications are easier to statically analyze and can help the ng update command refactor code more safely and precisely when you are updating to future versions of Angular.
Specifically, strict mode affects newly generated applications in the following way:
- Enables
strictmode in TypeScript, as well as other strictness flags recommended by the TypeScript team. Specifically,forceConsistentCasingInFileNames,noImplicitReturns,noFallthroughCasesInSwitch. - Turns on strict Angular compiler flags
strictTemplates,strictInjectionParametersandstrictInputAccessModifiers. - Reduces the bundle size budgets for the
initialandanyComponentStylebudget types by 75% compared to the previous defaults.
You can apply these settings at the workspace and project level.
Using the basic ng new command to create a new workspace and application automatically uses strict mode, as in the following command:
ng new [project-name]
To create a new application in the strict mode within an existing non-strict workspace, run the following command:
ng generate application [project-name] --strict
