πŸ‘‹ RxHttp

HTTP Client that uses Fetch API built with TypeScript that supports real-time JSON streams. It runs in NodeJS and Browser. It's powered by RXJS.

Why?

The Fetch API is the modern API for making http requests -- both long lived (streams) and traditional (simple). And RxJS makes it extremely convenient to build, chain, and consume asyncronous streams. These technologies all compliment each other well enough that it was worth creating this lib.

Features

πŸ“€ Universal -- Works on both NodeJS and Browser

🌊 Real-time -- Supports long-lived real-time Chunked JSON streams

πŸ†˜ Complete Observable Lifecycle -- Simple request lifecycle uses Observable callback functions (next, error, and complete). Once the connection completes, or all subscribers have unsubbed, the connection will be cleaned up to ensure there aren't any memory leaks.

The Most Bare Bones Example With Defaults

import { HttpRequest } from '@mkeen/rxhttp';

new HttpRequest<any>('https://localhost/simple')
.subscribe(
  response => console.log('received response, connection closed', response);
);

// Output:
// received response, connection closed , {...}

Simple (Request/Response) Request Example

import { HttpRequest, FetchBehavior } from '@mkeen/rxhttp';

interface Person {
  name: string;
  email: string;
}

new HttpRequest<Person>(
  'https://localhost/person',
  { method: 'POST', body: {
    email: 'mwk@mikekeen.com',
    name: 'Mike Keen'
  } }
)
.fetch()
.subscribe(
  response => console.log('person created successfully, connection closed', response)
);

// Output:
// person created successfully, connection closed, {...}

Simple (Request/Response) Request With Error Handling Example

import { HttpRequest, FetchBehavior } from '@mkeen/rxhttp';

interface Person {
  name: string;
  email: string;
}

new HttpRequest<Person>(
  'https://localhost/person',
  { method: 'POST', body: {
    email: 'mwk@mikekeen.com',
    name: 'Mike Keen'
  } },
  FetchBehavior.simple
)
.fetch()
.subscribe(
 (response: Person) => {
    console.log('person created successfully, connection closed', response);
  },
  
  (error: any) => {
    console.error('http error');
  },
  
  () => {
    console.log('connection closed');
  }
);

// Output:
// person created successfully, connection closed, {...}

Streaming Request Example

import { HttpRequest, FetchBehavior} from '@mkeen/rxhttp';               

interface Person {
  name: string;
  email: string;
}

const personStream = new HttpRequest<Person>(
  'https://localhost/person', {
    method: 'GET'
  }, FetchBehavior.stream
)
.fetch()
.subscribe(
  (incoming_data: Person) => {
    console.log('got person update: ', incoming_data);
  },
  
  (error: any) => {
    console.error('http error');
  },
  
  () => {
    console.log('connection closed');
  }
);

// Output:
// got person update: , {id: 1 ...
// got person update: , {id: 2 ...
// got person update: , {id: 1 ...
// ...
