Is it possible to read the value a file without using the download function?
Something instead of:
storageRef.child('text.txt').getDownloadURL().then(function() {
...
});
Something like:
storageRef.child('text.txt').getValue().then(function(value) {
alert(value)
});
I had the same trouble with getting content of the file in Firebase Storage, but finally, I found there is no way to read the file content directly. However, I did it like this.
fileRef.getDownloadURL()
.then(url => {
var xhr = new XMLHttpRequest();
xhr.responseType = 'json';
xhr.onload = function(event) {
var json= xhr.response;
console.log(json); // now you read the file content
};
xhr.open('GET', url);
xhr.send();
})
.catch(err => {
// process exceptions
})
What is important was configuring the CORS settings. You can find the instructions here.
Skipping this instruction made me consume much time :/
I hope others avoid the same mistakes. Thanks.
There is currently no available function to directly read a file in Firebase Storage in JavaScript without downloading it first.
You can file a Feature Request here, if you think this would be really useful.
