Apollo GraphQL Resolvers and Data Source separation

Resolvers can perform asynchronous call to fetch data. Using the specific implementation to perform the fetch in the resolver cause the resolver to have high-coupling into the technology to access the data but also increase the complexity of the resolver by boosting the size of each function with the request’s details. Apollo’s resolver allows to […]

GraphQL Query with Argument

A part of me wish that the flexibility of GraphQL would extend further in term of parameter to a query. The reality is that the maintainer of a GraphQL service must provide a set of acceptable inputs. The rational is that GraphQL needs to query a services or any source of data in a known […]

GraphQL Context

GraphQL has a mechanism to pass information to every resolver. The resolvers are at the core of resolving core logic about how to fetch the data. It is a centerpiece in term of security by allowing to know which user is authenticated and how to filter the information of this particular one. The resolver’s role is […]

Apollo Server and Secured Playground

In the last article of the series on how to create a GraphQL server with TypeScript and Apollo I demonstrate how easy is to setup the playground. However, there is still a piece that is missing and is authentication. In first post, I explicitly mentioned that every request goes first through Apache that has a special […]

Apollo Server Playground

Apollo comes with a handy playground. The playground is simple web portal that allows a rich experience to craft a GraphQL query against the Apollo GraphQL server. The interactive system gives autocomplete, schema discovery and display the response. It is a very valuable tool when developing because you do not need to use any external […]

Install Apollo Server to host a GraphQL service

This is the second post about my journey on prototyping a GraphQL service to abstract all REST and gRPC services that we have at Netflix Open Connect. You can consult the first article that was describing GraphQL and the high-level architecture to have a better idea of the motivation. In this article, I’ll start diving […]

Getting Started with GraphQL for Netflix Open Connect

I recently started an initiative about GraphQL for Netflix Open Connect. Netflix already invests in GraphQL and some of the other teams previously discussed on the Netflix’s Medium page here and there. I’ll approach the writing of my discovery with GraphQL not in hindsight but during my journey. What is GraphQL? GraphQL is an open source […]

Using OneNote to record online classes

I am taking online classes for my master degree in machine learning at Georgia Tech. For the first three semesters, I used Google Doc to write down all my notes during lecture. The lectures are provided by Udacity which are using videos to teach the content. After three semesters, I realized that my way of […]
