Testing Google's firebase.
- This app is deployed at https://app1-6affb.firebaseapp.com/
- The
bigbenendpoint can be accessed at https://app1-6affb.firebaseapp.com/bigben
$ npm install -g firebase-tools
$ firebase login
$ firebase init
Create firebase.json file as described in https://firebase.google.com/docs/hosting/deploying:
{
"hosting": {
"public": "app",
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
]
}
}
Create a simple home page:
$ mkdir public
$ echo "hello" > public/index.html
Initialize functions as decribed in https://firebase.google.com/docs/functions/get-started. I picked JavaScript.
$ firebase init functions
It created a functions directory. I then updated the functions/index.js with the bigben function as described in https://firebase.google.com/docs/hosting/functions:
const functions = require('firebase-functions');
exports.bigben = functions.https.onRequest((req, res) => {
const hours = (new Date().getHours() % 12) + 1 // london is UTC + 1hr;
res.status(200).send(`<!doctype html>
<head>
<title>Time</title>
</head>
<body>
${'BONG '.repeat(hours)}
</body>
</html>`);
});Also updated firebase.json file with the rewrite rule:
"rewrites": [ {
"source": "/bigben", "function": "bigben"
} ]
Then, just deploy. Note that this step took a long time (in minutes).
$ firebase deploy
