How to Check Version in TypeScript
Versions are a very important concept for building software. Some dependencies work only with certain software versions; therefore, it is very important to know the exact version of the software.
TypeScript provides some ways to check the version of the build either globally or within the local dependencies. This tutorial will focus on checking the version of the installed build of TypeScript.
Install TypeScript
TypeScript can be installed globally or within your project’s dependencies, which may be a node-based project, a ReactJS project, or any JavaScript framework-based project. Install TypeScript globally on the system.
npm install -g typescript
The above command should be used in the terminal, provided that node and npm are installed. To install TypeScript locally among one of its dependencies, use the command below.
npm i typescript
Check TypeScript Version Globally
TypeScript may be installed globally on one’s system, and the version can be checked via the tsc command.
tsc -v
// or
tsc -version
The globally installed TypeScript version may differ from the locally installed TypeScript version.
Check TypeScript Version Locally
The exact version installed as a package can be found using the npm command.
npm ls typescript
Moreover, the locally installed TypeScript version can be found using the locally installed tsc binary.
./node_modules/bin/tsc -v
TypeScript has seen a lot of version changes over the years ranging from 1.0.0 to 4.0. Any version that says ^3.7.0 means that on a new install, the next update can update the version to a new version more than the minor version mentioned, which can be 3.7.1, 3.8.0, etc.
If the version is ~3.7.0, then the new versions on a fresh install can be 3.7.1, 3.7.2 but never 3.8.
