# Locally in your project.
npm install -D typescript
npm install -D ts-node
# Or globally with TypeScript.
npm install -g typescript
npm install -g ts-node
# Depending on configuration, you may also need these
npm install -D tslib @types/node
Tip: Installing modules locally allows you to control and share the versions through
package.json. TS Node will always resolve the compiler from
cwd before checking relative to its own installation.
