Convert json to graphql query9/2/2023 This public API uses Countries List and provinces as data sources, so the schema follows the shape of those data, with a few exceptions: You could get such data from the Countries GraphQL API which is a public GraphQL API for information about countries, continents, and languages. Let’s say you were working on a project that required country-specific data, such as currency, or language. Working with Countries List, a GraphQL public API Hopefully this blog post will assist others. I tried interacting with a GraphQL server in R and felt like giving up even before getting anywhere. That’s where ghql, a GraphQL client for R, developed by Scott Chamberlain comes into play. In order for R to interact with any GraphQL API, it requires a GraphQL client. I picked ghql over the others because, it was an rOpenSci package. But, I knew it was a going to be a huge work, I guess I was ready for the huge work.Īfter spending days researching about the R packages that can interact with a GraphQL API, I found three packages. It was time for me to programmatically access data with GraphQL API from R. But, trust me its gradually evolving to do more than statistical computing and making of beautiful graphics. Well, that’s how it’s officially defined. R is a free software environment for statistical computing and graphics. □Īt work, our scripting language of choice is R. I am tempted to talk about the technicality behind it, but I won’t… maybe another time. But, just not in the format that I can work with. Probably, because of my lack of understanding of how GraphQL truly worked with spatial data. Why? Well, the GraphQL API I was working with fetches the geospatial data as json file instead of geojson. Now that I can query the API, everything should seem great. I recommend you try it out.Īfter hours of trying out the GraphQL playground, I finally understood the schema of the GraphQL API endpoint for the project I’m working on. I started off installing the GraphQL playground, which is now my go to tool to interact with GraphQL API and it offers a great workflow to understand the schema and structure of any GraphQL API. Basically, it is used to load data from a server to a client and it does this in a much more efficient manner than traditional methods and services. It’s designed to make APIs flexible, fast and friendly. GraphQL is a query language for application programming interfaces (APIs) that prioritizes giving clients exactly the data they request. But, I have heard a lot about it and how amazing it is for querying data. Before now, I haven’t worked with GraphQL. The project kicked off amazingly, until I was almost backed to the wall when I discovered that some of the data sources were served via a GraphQL API. Few months ago, I embarked on a full stack spatial data project at work.
