 If you need a generator for Open API v3 specs, you can test `typescript-axios` from [Swagger Codegen][codegen] ([added on 2020-09-21](https://github.com/swagger-api/swagger-codegen-generators/commits/master/src/main/java/io/swagger/codegen/v3/generators/typescript/TypeScriptAxiosClientCodegen.java)).
 
 ```bash
-java -jar swagger-codegen-cli-3.0.24.jar generate -l typescript-axios -i swagger.json -o /api-client
+java -jar swagger-codegen-cli-3.0.24.jar generate -l typescript-axios -i ./swagger.json -o ./api-client
 ```

+There is also an npm package ([@openapitools/openapi-generator-cli](https://www.npmjs.com/package/@openapitools/openapi-generator-cli)) which exposes this generator. You can use it the following way in your [scripts](https://docs.npmjs.com/cli/using-npm/scripts):
+
+```json
+{
+  "scripts": {
+    "generate": "openapi-generator-cli generate -i ./swagger.json -g typescript-axios -p \"withoutRuntimeChecks=true,withInterfaces=true\" -o ./api-client"
+  }
+}
+```
