When you develop with golang in a team, sometimes someone (it's me!) forget to include go.mod , or forget to run go mod tidy . Then the diffs will be included in other pull request. (That sucks)
BackgroundI need a file uploader for some people. I never met them and they also don't know me.I just want to gather movie clips from them for my friends wedding party.At first, I planned to use email with large file sender system. But it looked very slow and it looked not secure.Then I thought it's good to use AWS S3 to store it.I'd like users to use social login for auth then they can upload files for security and audit reason.I investigate some S3 API and Cognito but it's not easy both of users and me!So I choose Firebase Auth and Google login, I already know Firebase Hosting and Authentication.It's a piece of cake!
