+# Electron request
+
+The HTTP engine for the Advanced REST Client application.
+
+It works in the Electron's renderer process and allows to make a HTTP request resulting with detailed response.
+
+The detailed response contains information about redirects and timings similar to the ones presented by Chrome Dev Tools.
+
+## Usage
+
+The library contain two HTTP clients:
+
+- `SocketRequest` - ARC's original and own HTTP client. Operates directly on the socket.
+- `ElectronRequest` - A request engine using higher level Node's APIs
+
+Both classes use the same configuration and produce the same output.
+
+### Socket request
+
+Originally `SocketRequest` was develop for ARC Chrome Application as Chrome apps don't have access to low level request APIs and therefore the application was unable to produce detailed information about the request.
+
+```javascript
+import { SocketRequest } from '@advanced-rest-client/electron-request';
+
+const opts = {
+  timeout: 30000,
+  hosts: [{from: 'domain.com', to: 'other.com'}],
+  followRedirects: true
+};
+const id = 'some-id';
+const request = {
+  url: 'http://api.domain.com',
+  method: 'GET',
+  headers: 'x-test: true'
+};
+
+const connection = new SocketRequest(request, id, opts);
+request.on('load', (id, response, transport) => {});
+request.on('error', (error, id, transport, response) => {});
+try {
+  await connection.send();
+  console.log('Request message sent.');
+} catch (cause) {
+  // usually it means that the server is down or configuration is invalid (URL).
+  console.error('Connection error', cause);
+}
+```
+
+The `transport` is defined in `@advanced-rest-client/arc-types` as `TransportRequest` interface and describes the final message that has been sent to the endpoint. This includes all transformations applied to the request like added headers.
+
+### Native request
+
+Electron application can access Node's APIs and therefore `SocketRequest` can be eventually replaced to reduce amount of code to maintain.
+
+```javascript
+import { ElectronRequest } from '@advanced-rest-client/electron-request';
+
+const opts = {
+  timeout: 30000,
+  hosts: [{from: 'domain.com', to: 'other.com'}],
+  followRedirects: true
+};
+const id = 'some-id';
+const request = {
+  url: 'http://api.domain.com',
+  method: 'GET',
+  headers: 'x-test: true'
+};
+
+const connection = new ElectronRequest(request, id, opts);
+request.on('load', (id, response, transport) => {});
+request.on('error', (error, id, transport, response) => {});
+try {
+  await connection.send();
+  console.log('Request message sent.');
+} catch (cause) {
+  // usually it means that the server is down or configuration is invalid (URL).
+  console.error('Connection error', cause);
+}
+```
