via npm
TypeScript is available as a package on the npm registry available as "typescript".
You will need a copy of Node.js as an environment to run the package. Then you use a dependency manager like npm, yarn or pnpm to download TypeScript into your project.
npm install typescript --save-dev
All of these dependency managers support lockfiles, ensuring that everyone on your team is using the same version of the language. You can then run the TypeScript compiler using one of the following commands:
npx tsc
npx tsc basico.ts
npx tsc -v
Monitora o arquivo js para atualizar... npx tsc -w
COMMON COMMANDS
tsc Compiles the current project (tsconfig.json in the working directory.)
tsc app.ts util.ts Ignoring tsconfig.json, compiles the specified files with default compiler options.
tsc -b Build a composite project in the working directory.
tsc --init Creates a tsconfig.json with the recommended settings in the working directory.
tsc -p ./path/to/tsconfig.json Compiles the TypeScript project located at the specified path.
tsc --help --all An expanded version of this information, showing all possible compiler options
tsc --noEmit tsc --target esnext Compiles the current project, with additional settings.
COMMAND LINE FLAGS
--help, -h Print this message.
--watch, -w Watch input files.
--all Show all compiler options.
--version, -v Print the compiler's version.
--init Initializes a TypeScript project and creates a tsconfig.json file.
--project, -p Compile the project given the path to its configuration file, or to a folder with a 'tsconfig.json'.
--build, -b Build one or more projects and their dependencies, if out of date
--showConfig Print the final configuration instead of building.
