OpenAPI API Client Generation and Compilation

Generate an API client from an OpenAPI schema in YAML format and create a rtk-query api client. This package streamlines this process and ensures a smooth workflow.

Dependencies

1. Node.js and npm: Ensure you have Node.js and npm installed on your system. You can download them from nodejs.org.

Installation

``bash
npm install @layer5/rtk-query-codegen
`

Usage

Run the script using the following command:

`bash
rtk-query-codegen -i /path/to/schema.yml -o /path/to/generated-api.js -c /path/to/codegen-config.json
`

Config File Options

$3

`
{
apiFile: string
schemaFile: string
apiImport?: string
exportName?: string
argSuffix?: string
responseSuffix?: string
hooks?:
| boolean
| { queries: boolean; lazyQueries: boolean; mutations: boolean }
tag?: boolean
outputFile: string
filterEndpoints?:
| string
| RegExp
| EndpointMatcherFunction
| Array
endpointOverrides?: EndpointOverrides[]
flattenArg?: boolean
}
`

$3

If you only want to include a few endpoints, you can use the filterEndpoints config option to filter your endpoints.

`
{
// ...
// should only have endpoints loginUser, placeOrder, getOrderById, deleteOrder
filterEndpoints: ['loginUser', /Order/],
}
`

$3

If an endpoint is generated as a mutation instead of a query or the other way round, you can override that.

`
{
// ...
"endpointOverrides": [
{
"pattern": "loginUser",
"type": "mutation"
}
]
}
`

$3

Setting hooks: true will generate useQuery and useMutation hook exports. If you also want useLazyQuery hooks generated or more granular control, you can also pass an object in the shape of: { queries: boolean; lazyQueries: boolean; mutations: boolean }.

$3

`

schemaFile: 'https://petstore3.swagger.io/api/v3/openapi.json',
apiFile: './src/store/emptyApi.ts',
outputFiles: {
'./src/store/user.ts': {
filterEndpoints: [/user/i],
},
'./src/store/order.ts': {
filterEndpoints: [/order/i],
},
'./src/store/pet.ts': {
filterEndpoints: [/pet/i],
},
},
}
`

The Api.js file

The api.js file contains the generated api endpoints , it injects them into the base rtk client . And then exports all the hooks to use them .
If we need to override an api endpoint we can injectEnpoints in a separate file .

Troubleshooting

- If any of the steps fail, the script will exit with a non-zero status code, indicating a failure. Review the error messages to diagnose and resolve any issues.

- Ensure that the Bash script is executable by running chmod +x generate-api.sh.

Important Notes

- Make sure the OpenAPI schema (schema.yml`) is updated with latest changes and doesnt contain any breaking changes .

- Always validate and test the generated API client to ensure it functions as expected.
