This repository is the JavaScript generator for the OpenAPI Forge, see that repository for usage instructions:
https://github.com/ScottLogic/openapi-forge
The client API it generates is suitable for running in the browser (after being bundled appropriately), or via node. The generated code uses the Fetch API, and as a result you'll need to use node v18 or greater.
You should consult the OpenAPI Forge repository for a complete user guide. The following is a very brief example that quikcly gets you up-and-running with this generator.
Run the forge command to generate a client API using this generator as follows:
$ openapi-forge forge \
https://petstore3.swagger.io/api/v3/openapi.json \
openapi-forge-javascript \
-o api
This will generate various files in the api folder.
Add the following index.js in the api folder:
const ApiPet = require("./apiPet");
const Configuration = require("./configuration");
const transport = require("./fetch");
// create an API client
const config = new Configuration(transport);
config.basePath = "https://petstore3.swagger.io";
const api = new ApiPet(config);
// use it!
(async () => {
await api.addPet({
id: 1,
name: "Fido",
photoUrls: [],
});
const pet = await api.getPetById(1);
console.log(pet.name);
})();To test the API, this example adds a Pet named “Fido” to the Pet Store, then retrieves it via its id, logging the name. You can run the example as follows:
% node index.js
Fido
You'll need to bundle the files into a single script, there are various tools that can be used for this purpose, but browserify is one of the simplest:
% npx browserify index.js -o bundle.js
Next create a simple HTML file that loads this script:
<html>
<script src="bundle.js"></script>
</html>
Load the above page in a browser and you should see Fido logged to the console.
OpenAPI Forge is opinionated in its approach, we don't provide a vast range of configuration options, just the essentials! You can list the generator-specific configuration options by running the generate-options command as follows:
% openapi-forge generator-options openapi-forge-javascript
This generator has a number of additional options which can be supplied when executing the 'forge' command.
Options:
--generator.moduleFormat <value> The module format to use for the generated code. (choices: "commonjs", "esmodule",
default: "commonjs")
The OpenAPI Forge project details the process for creating a new generator. The documentation gives a few generator-specific instructions.
To run this generator, you also need to have [OpenAPI Forge] installed, or the repository checked out. Assuming you have it installed as a global module, you can run this generator as follows:
$ openapi-forge forge \
https://petstore3.swagger.io/api/v3/openapi.json \
. \
-o api \
This generates an API from the Pet Store swagger definition, using the generator within the current folder (.), outputting the results to the api folder.
The standard test script is used to execute the BDD-style tests against this generator.
npm run test
The script expects that the openapi-forge project (which is where the BDD feature files are located) is checked out at the same folder-level as this project.
Two scripts are available to help you find linting errors:
npm run lint:check:all
This runs eslint in check mode which will raise errors found but not try and fix them. This is also ran on a PR and a push to main. It will fail if any errors were found.
npm run lint:write:all
This runs eslint in write mode which will raise errors found and try to fix them.
