Genzy Client

Getting started:

1. npm init -y
2. npm i -S genzy-client
3. Define services

class UserService {
  async createUser(user) {}
}

class AccountService {
  async getAllAccounts() {}
  async createAccount(account) {}
}

4. Create a GenzyContainer of remote services

import { GenzyContainer } from 'genzy-client';

const host = 'http://localhost:3000';

const usersGenzyContainer = new GenzyContainer()
  .ofRemote(UserService, host)
  .andRemote(AccountService, host);

// The instances are available for custom usage
const { userService, accountService } = usersGenzyContainer.services();

// Use the services
accountService.createAccount({
  username: 'test',
  email: '[email protected]',
  firstName: 'Test',
  lastName: 'Test',
})
.then(newAccount => console.log(newAccount)) // created account from server
.catch(error => console.log(error));

// Fetch all accounts
const allAccounts = await accountService.getAllAccounts();

# 2 requests have been sent
# POST /api/account-service/create-account
#   body: { args: [{
#     username: 'test',
#     email: '[email protected]',
#     firstName: 'Test',
#     lastName: 'Test',
#   }] }
# GET /api/account-service/get-all-accounts

Interceptors

// Intercept all service calls
const usersGenzyContainer = new GenzyContainer()
  .ofRemote(UserService, host)
  .interceptAllCalls(({setHeader, getHeader, setBody, getBody}) => {
    setHeader('Authorization', 'Bearer <token>');
  });

// Intercept only specific method calls
const usersGenzyContainer = new GenzyContainer()
  .ofRemote(UserService, host)
  .interceptCalls({
    userService: {
      getTest({setHeader, getHeader, setBody, getBody}) {
        setBody({ ...getBody(), timestamp: new Date() });
      }
    }
  });

// Define interceptors with an interceptor class
class UserServiceCallInterceptor {
  getTest({setHeader, getHeader, setBody, getBody}) {
    setHeader('classCallInterceptor', 'Works!')
  }
}
const usersGenzyContainer = new GenzyContainer()
  .ofRemote(UserService, host)
  .interceptCalls({
    userService: UserServiceCallInterceptor
  });

// Intercept all service results
const usersGenzyContainer = new GenzyContainer()
  .ofRemote(UserService, host)
  .interceptAllResults(({setHeader, getHeader, setBody, getBody}) => {
    validateBody(getBody());
    setToken(getHeader('Token'));
  });

// Intercept only specific method results
const usersGenzyContainer = new GenzyContainer()
  .ofRemote(UserService, host)
  .interceptResults({
    userService: {
      getTest({setHeader, getHeader, setBody, getBody}) {
        setBody({ ...getBody(), count: getBody().items.length });
      }
    }
  });

// Define interceptors with an interceptor class
class UserServiceResultInterceptor {
  getTest({setHeader, getHeader, setBody, getBody}) {
    setHeader('classResultInterceptor', 'Works!')
  }
}
const usersGenzyContainer = new GenzyContainer()
  .ofRemote(UserService, host)
  .interceptResults({
    userService: UserServiceResultInterceptor
  });
