问题 I have a Google Cloud Function triggered by Firebase Storage, and I want to generate thumbnails. While the Node.js docs have an example that uses ImageMagick there is no such equivalent for the python runtime. What would be an acceptable approach keeping performance in mind ?

问题 I am a total amateur to Firebase. My short-term objective here is to read data from a text file that I uploaded onto Firebase. This is the code (copy-pasted from the docs): storageRef.child('images/stars.jpg').getDownloadURL().then(function (url) { var xhr = new XMLHttpRequest(); xhr.responseType = 'blob'; xhr.onload = function(event) { var blob = xhr.response; }; xhr.open('GET', (/*here I put the url of the file*/)); xhr.send(); }); I am at odds from here. How do I read this file and copy

问题 I deployed a cloud function in firebase but instead of using a local emulator for testing purposes, I redeployed it several times to debug and test. After this, I see that my usage in the cloud storage in firebase is upwards of 500 MB although I have not stored any files in the Cloud Storage. Is this due to the multiple redeployments of the function? If yes, will deleting the cloud function free up this space or is there another way. Thanks. 回答1: Yes, deploying a Cloud Function will take up
