Auto incrementing IDs for MongoDB

masnun — Thu, 06 Dec 2018 17:14:35 +0000

If you’re familiar with relational databases like MySQL or PostgreSQL, you’re probably also familiar with auto incrementing IDs. You select a primary key for a table and make it auto incrementing. Every row you insert afterwards, each of them gets a new ID, automatically incremented from the last one. We don’t have to keep track […]

For building quick APIs in Python, I have mostly depended on Flask. Recently I came across a new API framework for Python 3 named “API Star” which seemed really interesting to me for several reasons. Firstly the framework embraces modern Python features like type hints and asyncio. And then it goes ahead and uses these […]

If you’re a Python developer, you probably know about pip and the different environment management solutions like virtualenv or venv.

Golang: Interface

masnun — Sun, 22 Oct 2017 19:06:16 +0000

In Go or Golang, declaring an interface is pretty simple and easy. [crayon-6a203fd1a847f598108445/] We just defined an interface named Printer that required an implementer to have a method named Print which takes a string parameter and returns nothing. Interfaces are implemented implicitly in Go. Any type that has the Print(string) method implements the interface. There is no need to […]

As we can already guess from the name, a Proxy object works as a “proxy” to another object and allows us to customize the behavior of the said object in certain ways. Let’s say you have an obj named awesomeAPI which has some properties and methods. You want to “trap” any calls to the object. May […]

We encounter promises in real life every now and then. You have promised to deliver that project within the next week. Your friend has promised to play Overwatch with you tonight. If you think about it, promises are everywhere around us. Promises in JavaScript also play similar roles. A Promise object in JS is an […]
