Loading tsconfig.json

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

Configuration Options

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.

Programmatic Usage

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

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