When deploying the following hello-world equivalent code I get the error shown in the end:-
$ ls -lR
.:
total 8
-rw-r--r-- 1 hgarg hgarg 3 Aug 29 14:55 firebase.json
drwxr-xr-x 2 hgarg hgarg 4096 Aug 29 11:56 functions
./functions:
total 4
-rw-r--r-- 1 hgarg hgarg 1678 Aug 29 11:56 index.js
firebase.json looks like this:-
{}
and index.json like this:-
'use strict';
const functions = require('firebase-functions');
exports.search = functions.https.onRequest((req, res) => {
if (req.method === 'PUT') {
res.status(403).send('Forbidden!');
}
var category = 'Category';
console.log('Sending category', category);
res.status(200).send(category);
});
But deploying fails:-
$ firebase deploy
Error: Cannot understand what targets to deploy. Check that you specified valid targets if you used the --only or --except flag. Otherwise, check your firebase.json to ensure that your project is initialized for the desired features.
$ firebase deploy --only functions
Error: Cannot understand what targets to deploy. Check that you specified valid targets if you used the --only or --except flag. Otherwise, check your firebase.json to ensure that your project is initialized for the desired features.
it would be better to pre-populate the firebase with the default options. I choose that I wanted to use only hosting the firebase.json should have be created with the default hosting option.
{
"hosting": {
"public": "public"
}
}
or you try run
firebase init
again.
