ts-node ignores d.ts files while tsc successfully compiles the project

Question

Having compiled my TypeScript project successfully, I intended to run it in VS Code's debug mode using ts-node. Problem is, ts-node can't find d.ts files I created (while tsc has no problem with it).

Project structure is:

/     conf/     dist/     src/         types/ package.json tsconfig.json 

tsconfig.json relevant entries are:

{     "compilerOptions": {         "target": "es2017",         "module": "commonjs",         // "lib": [],         "sourceMap": true,         "outDir": "dist",         "rootDir": "src",         "moduleResolution": "node",         "baseUrl": ".",         "paths": {             "*": [                 "node_modules/*",                 "src/types/*"             ]         },         // "rootDirs": [],         // "typeRoots": [],         // "types": [],     },     "include": [         "src/**/*"     ] } 

The definition file ts-node can't find is src/types/global.d.ts:

import { App } from '../App';  declare global {     namespace NodeJS {         interface Global {             app: App;         }     } } 

So, trying to run it with ts-node I see:

TSError: ⨯ Unable to compile TypeScript: src/boot.ts(15,59): error TS2339: Property 'app' does not exist on type 'Global'. 

How to resolve it globally? I've found that /// <reference path="./types/global.d.ts" /> does the trick but I'd have to repeat it in every file using global.app.

My TypeScript version is 3.0.1

I was having a similar problem, but I could not add --files, because I run ts-node by registering the module through mocha (i.e. mocha -r ts-node/register ...).

I could solve it by adding a files and a ts-node section to tsconfig.json like this:

// tsconfig.json {   "ts-node": {     "files": true   },   "files": [     "src/index.ts",     "src/global.d.ts"   ],   "compilerOptions":{     //...   } }
