Send Request

Lightweight HTTP client for Node.

Installation

$ npm install send-request

Usage

Send HTTP GET request:

const sendRequest = require("send-request");

(async () => {
  const response = await sendRequest("https://httpbin.org/json");

  console.log(`Status Code: ${response.statusCode}`);
  console.log({ headers: response.headers });
  console.log(response.body); // Response as a string

  // If response's content type is a JSON, you get the parsed object.
  console.log(response.json);
})();

Recipes

Handling Error

const sendRequest = require("send-request");

(async () => {
  try {
    const response = await sendRequest("https://httpbin.org/status/400");
  } catch(error) {
    console.log(error.message);

    // If it's an HTTP error, it will have response property.
    if (error.response) {
      console.log(error.response.statusCode); // 400
      console.log(error.response.statusMessage);
      console.log(error.response.headers);
      console.log(error.response.body);
    }
  }
})();

Send HTTP POST Request with Body

If you don't set the content-type and content-length headers, it will be automatically added. The content-type will be set to application/x-www-form-urlencoded.

const sendRequest = require("send-request");

(async () => {
  const response = await sendRequest("https://httpbin.org/anything", {
    method: "POST",
    body: {
      foo: "bar"
    }
  });

  console.log(response.body);
})();

Send HTTP Request with JSON Body

If you don't set the content-type and content-length headers, it will be automatically added. The content-type will be set to application/json.

const sendRequest = require("send-request");

(async () => {
  const response = await sendRequest("https://httpbin.org/anything", {
    method: "POST",
    body: {
      foo: "bar"
    },
    json: true // Must be set to true
  });

  console.log(response.json);
})();

Sending File with FormData

You pass the FormData instance as a body. If you don't set the content-type and content-length headers, it will be automatically added. The content-type will be set to multipart/form-data. The json option won't have any effect.

const fs = require("fs");
const sendRequest = require("send-request");
const FormData = require("form-data");

(async () => {
  const file = fs.createReadStream("./test.txt");

  const form = new FormData();
  form.append("foo", "bar");
  form.append("my_file", file);

  const response = await sendRequest("https://httpbin.org/anything", {
    method: "POST",
    body: form
  });

  console.log(response);
})();

API

sendRequest(url, [{
  method,
  headers,
  auth: {
    username,
    password
  },
  body,
  json,
  encoding
}])

Parameters

• url (String): The URL to send the HTTP request to.
• method (optional String): The HTTP method to use, default to GET.
• headers (optional Object): The request headers to send.
• auth.username (optional String): The username for HTTP basic auth.
• auth.password (optional String): The password for HTTP basic auth.
• body (optional Object|FormData): The request body to send. It can be a plain JavaScript object or an instance of FormData.
• json (optional Boolean): Set to true if you want to send the request body with application/json content type. Default to false, which means that the request body will be sent as application/x-www-form-urlencoded. Note that you can still override the content type using the headers option.
• encoding (optional String|Null): The encoding to decode the incoming response. If set to null, the response's body will be a Buffer instance.

Returns

It returns a Promise which when resolved contains a response object. Here's an example of a reponse object:

{
  statusCode: 200,
  statusMessage: "OK",
  headers: {
    "content-type": "application/json"
  },
  body: '{"foo": "bar"}',
  json: {
    foo: "bar"
  }
}

• statusCode (Number): The HTTP status code.
• statusMessage (Number): The HTTP status message (reason phrase).
• headers (Object): The response's headers.
• body (String): The response's body.
• json (Object): The parsed JSON body. It only exist if the response's content type is application/json.
