Learn React with TypeScript 3

Creating tsconfig.json

As outlined in Chapter 1, TypeScript Basics, tsconfig.json specifies how our TypeScript code is compiled and transpiled.

Let's create a new file called tsconfig.json in the root of our project, and enter the following:

{   "compilerOptions": {     "target": "es5",     "module": "es6",     "moduleResolution": "node",     "lib": ["es6", "dom"],    "sourceMap": true,     "jsx": "react",     "strict": true,     "noImplicitReturns": true,    "rootDir": "src",    "outDir": "dist",  },  "include": ["**/*.ts", "**/*.tsx"],  "exclude": ["node_modules"]}
