npm install -g typescript

• Execute TypeScript files with node
• Interactive REPL

# Execute a script as you world normally with `node`.
ts-node script.ts

# Starts the TypeScript REPL.
ts-node

# Execute code snippets with TypeScript.
ts-node -e 'console.log("Hello, world!")'

# Execute and print code snippets with TypeScript.

Tape:

ts-node node_modules/tape/bin/tape src/**/*.spec.ts

Typescript Node automatically loads tsconfig.json options and referenced files from the current directory using tsconfig.

You can set options by passing them in before the script.

ts-node --compiler ntypescript --project src --ignoreWarnings 2304 hello-world.ts

• project Location to resolve tsconfig.json from.
• compiler Use a custom, require-able TypeScript compiler compatible with typescript@>=1.5.0-alpha.
• ignoreWarnings Set an array of TypeScript diagnostic codes to ignore.
• disableWarnings Ignore all TypeScript errors.

require('ts-node').register({ /* options */ })

// Or using the shortcut file.
require('ts-node/register')
