We have already seen that using node app.js as a command boots our server and, yes, we know about that. But we have not learned to configure the command. Node package manager (npm) provides a way to configure our server start command using a scripts key in a package.json. This can be shown in the following snippet of package.json:
{
"name": "test-node-app",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "node app.js"
},
"author": "",
"license": "ISC",
"dependencies": {
"handlebars": "^4.0.11",
"hapi": "^17.2.0"
}
}In the preceding code, we added a start key inside the script's literals and provided our actual Node server start command as the value. Now let's run our new command as follows:
npm startWoot! Our server starts running. Here the start key is already recognized by npm...
