This month, I learned to used Multer for a react project that I've been working on. It took me close to 6 days to get both the back-end and front end to work for Multer. There were times when I really struggled but in the end, I didn't give up and it's so rewarding to finally figured it out. Being able to upload a file successfully, especially a photo, and have it save to the database was something I was thinking about learning to do since December.
Many of the errors I had at the beginning were mainly missing the little stuff, like forgetting to deploy the latest changes to my server or having a syntax error.
Here are three resources that I've found really useful for my first implementation with Multer:
It took some heavy studying for me to finally get it to work but now I can use Multer for all of my future projects that require file uploading from now on
Note:
Remember to use axios to call to Multer, not fetch.
