Rapini is a tool that generates React Query (or SWR) hooks, Axios requests and Typescript types, based on an OpenAPI spec file. The generated code is packaged conveniently so that it can be published as a package on any NPM registry.
- 🚴 Generates axios calls for every endpoint, with typed payload.
- 🏌️ Generates custom react hooks that use React Query's
useQueryanduseMutationhooks for each axios call. Optional to generate custom hooks that use SWR'suseSWRhook. - 🚣 Generates query keys for every hook.
- 🏋️ Generates strong typescript types for all inputs, outputs, and options.
Rapini is a CLI tool so you can execute the remote npm package directly for convenience
npx rapini [library] [options]eg:
# For React Query V3
npx rapini react-query -p path/to/openapi.yaml
# For TanStack Query 4
npx rapini react-query v4 -p path/to/openapi.yaml
# For TanStack Query 5
npx rapini react-query v5 -p path/to/openapi.yaml
# For SWR
npx rapini swr -p path/to/openapi.yamlThis will generate the package code based on an OpenAPI file at path/to/openapi.yaml. The outputted code will be packaged in a way to just publish it as your own NPM package and then import it in your React project.
Usage: rapini [options] [command]
Generate a package based on OpenAPI
Options:
-V, --version output the version number
-h, --help display help for command
Commands:
react-query [options] [version] Generate a Package for TanStack Query V4 or React Query V3
swr [options] Generate a Package for SWR (stale-while-revalidate)
help [command] display help for command
Usage: rapini react-query [options] [react-query-version]
Generate a Package for TanStack Query V4 or V5, or legacy React Query V3
Options:
-p, --path <path> Path to OpenAPI file
-n, --name [name] Name to use for the generated package (default: "rapini-generated-package")
-pv, --package-version [version] Semver version to use for the generated package (default: "1.0.0")
-o, --output-dir [directory] Directory to output the generated package (default: "rapini-generated-package")
-b, --base-url [url] Prefix every request with this url
-r, --replacer [oldString] [newString...] Replace part(s) of any route's path with simple string replacements. Ex: `-r /api/v1 /api/v2` would replace the v1 with v2 in every route
-h, --help display help for command
Usage: rapini swr [options]
Generate a Package for SWR (stale-while-revalidate)
Options:

-pv, --package-version [version] Semver version to use for the generated package (default: "1.0.0")
-o, --output-dir [directory] Directory to output the generated package (default: "rapini-generated-package")
-b, --base-url [url] Prefix every request with this url
-r, --replacer [oldString] [newString...] Replace part(s) of any route's path with simple string replacements. Ex: `-r /api/v1 /api/v2` would replace the v1 with v2 in every route
-h, --help display help for command
Let's say you have an OpenAPI file that looks like this one.
Once you run the CLI tool to generate the React Query code, you can then cd into the generated directory, run npm install && npm run build then npm publish with your own package name to publish it to your own registry, then import and use it like this:
import { initialize } from "your-custom-package";
import { axiosInstance } from "./your-custom-axios-instance";
// Can even import the generated Typescript Types if needed
import type { Pet } from "your-custom-package";
const config = initialize(axiosInstance);
const { usePets } = config.queries;
const MyComponent = () => {
const { data, isLoading, isError } = usePets();
return (
<ul>
{data.pets.map((pet) => (
<li key={pet.id}>{pet.name}</li>
))}
</ul>
);
};You must call initialize(axiosInstance) with your custom axios instance. The return value from the initialize will give you an object with everything you need, here is the return value with examples:
import { queryKeys } from "generated-package";
// queryKeys = { pets: () => ['pets'] } ...
const rapini = initialize(axiosInstance);
rapini.queries; // { usePets, usePetById } ...
rapini.mutations; // { useUpdatePet, useDeletePet } ... if generated by SWR, there will be no property `mutations`
rapini.requests; // { pets: () => axios.get<Pet[]>(...) } ...There may be times when you want extra functionality hooked into each hook's callbacks. You can do this normally by passing options to each hook, but if you want something more global - a config can be provided to the initialize function.
import { initialize, type Config } from "your-custom-package";
import type { QueryClient } from "react-query";
const config: Config = {
mutations: {
useCreatePet: (queryClient: QueryClient) => ({
onSuccess: () => showSuccessNotification(),
onError: () => showErrorNotification(),
}),
},
};
const rapini = initialize(axiosInstance, config);- Every request must have an
operationIddefined. TheoperationIdis used in many places in the final generated code.
