# 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 does the following:
|
|
|
|
* Enables [`strict` mode in TypeScript](https://www.typescriptlang.org/tsconfig#strict), as well as other strictness flags recommended by the TypeScript team. Specifically, `forceConsistentCasingInFileNames`, `noImplicitReturns`, `noFallthroughCasesInSwitch`.
|
|
* Turns on strict Angular compiler flags [`strictTemplates`](guide/angular-compiler-options#stricttemplates), [`strictInjectionParameters`](guide/angular-compiler-options#strictinjectionparameters) and [`strictInputAccessModifiers`](guide/template-typecheck#troubleshooting-template-errors).
|
|
* [Bundle size budgets](guide/build#configuring-size-budgets) have been reduced by ~75%.
|
|
|
|
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:
|
|
|
|
<code-example language="sh">
|
|
|
|
ng new [project-name]
|
|
|
|
</code-example>
|
|
|
|
To create a new application in the strict mode within an existing non-strict workspace, run the following command:
|
|
|
|
<code-example language="sh">
|
|
|
|
ng generate application [project-name] --strict
|
|
|
|
</code-example>
