graphql-client VS Jackson JSON Processor

An example of a Snowflake API request using Ruby. This example uses the Ruby standard library, so it doesn’t require additional dependencies; however, in production, you could use a library like GitHub’s own graphql-client for stronger typing.

This initializer is a straightforward client, and there are some improvements you can make here. First, it's never a good idea to hard-code API secrets in your code. A better option would be to use Rails secrets or environmental variables. Second, you can load the schema just once and dump it to disk to faster read after. There are examples in the library documentation on how to make these improvements. For our little project, we will keep it simple.

A couple of examples: graphql-client a Ruby client

We can then easily convert this string value into the array of Products using librares like Jackson.

The above class maps the json data to a java object we can work with. We use Lombok to generate constructors, getters and setters for our code and the Jackson Project to handle serialization and deserialization of json to pojo . We know the response is an array of objects representing the coffee and so above data structure is fit for this.

Jackson. Because JSON.

For my series of articles, I also wanted to see how this requirement to mapping values could be implemented with Jackson.

In practical terms, Jackson achieves the same purpose for Java. It was born as a Json parser, but nowadays supports multiple formats and it's widely used in the Java community.

How can Jackson library help you out?

Jackson para lidar com JSON;

An example of a Snowflake API request using Java. This example uses Java’s built-in HttpClient and constructs JSON manually, so it doesn’t require additional dependencies; however, in production, you should use a library like Jackson for constructing JSON. Additionally, for stronger typing, you could use Apollo’s Kotlin-based GraphQL client.
