PeterTypeScript is a superset of JavaScript and is widely used for developing large-scale applications. Angular, one of the most popular front-end frameworks is built using TypeScript. When working with Angular, knowing which version of TypeScript is being used in your project is important. In this blog post, we'll discuss identifying the TypeScript version in an Angular project.
Angular uses TypeScript as its primary language, meaning you will need to have TypeScript installed on your machine to develop Angular applications. Once you have TypeScript installed, you can check the version of TypeScript in your Angular project in the following ways:
Package.json file
The TypeScript version can be found in the package.json file of your Angular project. Open the package.json file and look for the "typescript" section. You will see the version of TypeScript that your Angular project is using. For example:
"devDependencies": {
"typescript": "^4.3.5"
}
Angular CLI
You can also check the TypeScript version using the Angular CLI. Open your terminal and run the following command in the root directory of your Angular project:
ng version
This command will display the version of Angular, TypeScript, and other packages used in your project.
TypeScript Compiler
Another way to check the TypeScript version is to use the TypeScript compiler. Open your terminal and run the following command in the root directory of your Angular project:
tsc --version
This command will display the version of TypeScript installed on your machine. If the version displayed matches the version specified in the package.json file, that is the version used in your Angular project.
The following table summarizes version compatibility between Angular, TypeScript, and Node.
In conclusion, identifying the TypeScript version in an Angular project is important when developing large-scale applications. You can check the version of TypeScript using the package.json file, Angular CLI, or TypeScript compiler. Once you have identified the TypeScript version, you can use it to ensure that your code is compatible with the specific version of TypeScript being used in your Angular project.
