We will locate the source files in lib and the tests in lib/test. We use gulp to compile the project and AVA to run tests. We can install the dependencies of our project with NPM:
npm init -y npm install ava gulp gulp-typescript --save-dev
In gulpfile.js, we configure gulp to compile our TypeScript files:
var gulp = require("gulp");
var ts = require("gulp-typescript");
var tsProject = ts.createProject("./lib/tsconfig.json");
gulp.task("default", function() {
return tsProject.src()
.pipe(ts(tsProject))
.pipe(gulp.dest("dist"));
});
We can download type definitions for NodeJS with NPM:
npm install @types/node --save-dev
We must exclude browser files in TypeScript. In lib/tsconfig.json, we add the configuration for TypeScript:
{
"compilerOptions": {
"target": "es6",
"module": "commonjs"
}
}
