GraphQL Optimization - Lookaheads - Prefetching

In previous posts, we saw how to optimize data between GraphQL Server and a backend server using the concepts of lookaheads and field filtering. In this post, we are going to leverage look aheads for other forms of optimization - especially prefetching resources.

GraphQL Optimization - Lookaheads

GraphQL offers a way to optimize the data between a client and a server. We can use the declarative nature of a GraphQL query to perform lookaheads. Lookaheads provide us a way to optimize the data between the GraphQL server and a backend data provider - like a database or another server that can return partial responses.

TypeScript - Typing object paths

In this post, I'm going to use some features of TypeScript that are often considered "advanced". In the first section, I'll mention most of the TypeScript features I'm going to use and also point to their documentation for references. The post is about how we can get stricter types for Object Paths for different use-cases.

Catch structural similarity of JavaScript code

This post is about how do we detect some of the cases where we have possibly repeated code in the same project or across multiple projects. This code if necessary can be extracted into a common module so as to avoid fixing bugs multiple times.

Modeling errors in GraphQL

GraphQL excels in modeling data requirements. Modeling errors as schema types in GraphQL is required for certain kinds of errors. In this post, let's analyze some cases where errors contain structured data apart from the message and the location information.

Removing sensitive files from git

If you've some file committed to a git repository, and you'd like to remove it, simply deleting the file and committing it again will not remove the file completely. It still lies in the git history. If you want to remove a file from git history, the history needs to be re-written. This post is about exactly doing that - rewriting git history such that the file to be removed stays removed.
