In my team we work on a lot of technologies, some we chose, some we did not mostly due to getting existing projects in while consultants were asked to leave our company. Nonetheless, we had some load testing to perform on our Open API stack. We decided that we needed to script it with one of the technologies we use. What do we currently have on our stack?

• Java - Spring boot
• Kotlin - Spring boot
• TypeScript - NestJS
• ReactJS with and without Redux and all the possible things around
• VueJS - NuxtJS
• Golang

Last month I read

So today I will talk about the file management into MongoDB. Indeed I met some issues while manipulating them so I thought some people could be happy to have a basic article on GridFS and MongoFiles.

I wanted to create a unique code that was readable which means different from what you get when you use UUID or anything else. And it was also necessary to increment this code every time a new document was created.

Sometimes when I develop with my friends they ask me: where did you get this habit to use final on all these objects? Why do you always want to use immutable objects?
