![]() ![]() Create a new requests.rb file with the following code. Everything we'll use in the following example is already built into Ruby. Making HTTP requests with Ruby is something that we can do without installing libraries. ![]() We can run this example with node request.js to get our JSON blob. Create a new request.js file with the following code. Since the JavaScript version of requests is no longer supported, we'll take advantage of got. Similarly to the Python instructions, we'll be making use of an HTTP library for JavaScript. Run the code with python request.py and you'll see a JSON blob! 3. At the end, if we get a 200 HTTP status code, use the JSON library to format the output. I'm a fan of f-strings - the new way to do string manipulation in Python - so I'm using that format. But, since this is an example, we can save it in the file.Ĭreate your endpoint URL and Authorization headers. In your newly created Python file, import the libraries. Since this is a new Python project, spin up a new virtual environment, install requests and create a new Python file. It's extremely simple although, unlike urllib, we will have to install it. There are few different ways to make an HTTP request in Python, which gives us options in how we'd make a GraphQL query. When that command is run in a terminal it will output a JSON blob matching that of our previous example! Every one of our examples following this will use a similar format to the cURL request we made. If you’re using your own query, space id and accessToken, go ahead and replace them. We have a query, so we can modify the cURL example provided in the Contentful developer docs.Įven though the Contentful GQL API supports both POST and GET, we'll be using POST exclusively in this blog post, because POST enables us to send the query as a part of the JSON payload. Since cURL is a command-line utility, we can dive into all of our arguments before moving onto programming languages. I'll be using the following query, space id and access token in this example, but feel free to substitute your own if you'd like to try it yourself. If the query doesn't have any errors a JSON blob containing the data from your space will show up on the right. ![]() GraphQL is self-documenting, meaning that we can use both the documentation explorer and GraphiQL's built-in autocompletion (brought up via ctrl-space) to create a query. Check out this blog post if you'd like to learn more, but the important part is it's already got some content models and content in the space.įrom GraphiQL we can start creating a query. ![]() Open up, replacing the spaceID and accessToken with your own.įor this example, I'm using the space from my Serverless SuperHero website. To find a query we can use GraphiQL, an in-browser GraphQL IDE. For the API endpoint, we can use Contentful's API Base URL, taken from the GraphQL docs. Getting both of those items via Contentful is a breeze. The pre-processing step of this library is based on timqian/gql-generator.Before we can get started, we need a query and an API endpoint to hit.No support for subscriptions yet – only queries and mutations Acknowledgments.That new REST API will have the same interface as the old one, and the new implementation can then be tested, endpoints migrated in stages, until a full migration to the underlying GraphQL API takes place. Executing a REST API call with missing or incorrect parameters automatically results in an informative error provided by GraphQL (which can be custom formatted to look like REST).Īn old REST API can be migrated to a new GraphQL API gradually, by first building the GraphQL API and using GraphQL2REST to generate a REST API on top of it, seamlessly. The resulting REST API enjoys the built-in data validation provided by GraphQL due to its strong type system. GraphQL2REST lets you create a truly RESTful API that might be very different than the original, unchanged GraphQL API, without writing a single line of code. Using apollo-link to work with a remote GraphQL server.Customizing and formatting response format.Filtering and shaping the responses on the client side.Mapping to GraphQL operations using conditional logic.Getting started: quick start & working example.This might be needed for very large schemas, when the schema has circular references or the GraphQL server has a strict query depth limit. The depth limit of generated client queries can be set in the pre-processing step. Use path.resolve(_dirname, ) for relative paths.Īll fields in options are optional, but init() will not be able to run without a valid manifest file and gqlGeneratorOutputFolder previously populated by generateGqlQueryFiles(). init ( schema, execute, gql2restOptions ) DELETE /api/users/ const expressRouter = GraphQL2REST. ![]()
