    basic-request

    A very basic library to send an HTTP request to a URL and get a result.

    Why Another Request Library?

    There are approximately 10000 request packages in npm. This one adds no extra dependencies, and uses the node.js convention of function(error, result) without any added parameters. No longer will you need to check the status code of the response; basic-request treats all status codes other than 200 as errors. The library can work with promises too.

    As an extra, basic-request follows redirects.

    Installation

    Install with npm:

    npm install basic-request
    

    Compatibility

    Versions 2 and later should be used at least with Node.js v8 or later:

    • Node.js v8 or later: ^2.0.0.
    • Node.js v6 or earlier: ^1.2.0.

    Usage

    In your code just require the package:

    var request = require('basic-request');

    GET

    To make a regular GET request use await request.get():

    const body = await request.get('http://httpbin.org/')
    console.log('Received %s', body);

    That is it! No wading through responses, parsing status codes or anything else; basic-request will do that for you. Any errors are thrown as exceptions.

    You can also use a callback in the traditional node.js fashion:

    request.get('http://httpbin.org/', function(error, body) {
        if (error) {
            return console.error('Could not access httpbin: %s', error);
        }
        console.log('Received %s', body);
    });

    It even follows redirects!

    You can see a couple of examples in the test file.

    PUT, POST, PATCH, DELETE

    The basic-request package supports PUT, POST, PATCH and DELETE methods, and will even stringify objects into JSON for you:

    try {
        const body = await request.post('http://httpbin.org/', {attribute: 'value'})
        console.log('Received %s', body);
    } catch (exception) {
        return console.error('Could not access httpbin with POST: %s', error);
    }

    Likewise with request.put(), request.patch(), request.delete(). Again, can be used with a traditional callback as last parameter:

    request.post('http://httpbin.org/', {attribute: 'value'}, function(error, body) {
        if (error) {
            return console.error('Could not access httpbin with POST: %s', error);
        }
        console.log('Received %s', body);
    });

    BLOAT ALERT

    A couple of additional features have crept in, using a second (optional) parameter params:

    request.get(url, params, callback);
    

    For post and put, it's a third (optional) parameter params:

    request.post(url, body, params, callback);
    request.put(url, body, params, callback);
    

    Retries

    Pass a retries param to retry requests a number of times:

    request.get('http://httpbin.org/', {retries: 2}, function(error, body) {
        [...]
    });

    Timeout

    Pass a timeout param to abort the query after the given number of milliseconds:

    request.get('http://httpbin.org/', {timeout: 1000}, function(error, body) {
        [...]
    });

    Headers

    Pass a headers param object to send each key as a header:

    var headers = {
        'content-type': 'application/x-www-form-urlencoded; charset=UTF-8',
    };
    request.post('http://httpbin.org/', {a: 5}, {headers: headers}, function(error, body) {
        [...]
    });

    Agent

    Pass an agent object to use for keep alive:

    request.get('http://httpbin.org/', {agent: new AgentKeepAlive()}, function(error, body) {
        [...]
    });

    By default, no agent is used. Consider using agentkeepalive if you need persistent connections, instead of the default agent.

    Buffer

    If params.buffer is truthy, then a raw buffer is returned instead of converting to string first.

    Parse JSON

    When the server response has content-type application/json then it will be parsed and returned as an object instead of a string:

    const result = await request.get('http://httpbin.org/json')
    console.log(`Type ${typeof result}`) //-> 'object'

    getResponse()

    In case you want to get the response stream and parse it yourself, basic-request since 1.2.0 supports getResponse():

    request.getResponse(url, method, body, params, callback);
    

    where method can be any HTTP valid method: GET, POST... and the callback will have the signature function(error, response). The remaining parameters are as explained above. body and params are still optional. Example:

    request.getResponse('http://httpbin.org/post', POST, {a: 5}, function(error, response) {
        if (error) return console.error('Could not post: %s', error);
        response.pipe(output);
    });

    getParsed()

    When want to need to have more visibility into the response you can use getParsed() (since 3.0.0):

    const parsed = await request.getParsed(url, method, body, params);
    

    Parameters are the same as in request.getResponse(), except that it does not accept a callback: it is always promise-based.

    The returned parsed object will have the following attributes:

    • status: HTTP status code.
    • headers: object with headers.
    • buffer: unparsed output buffer.
    • body: parsed body / JSON object.

    Example:

    const parsed = await request.getParsed('http://httpbin.org/post', POST, {a: 5})
    console.log(`Status ${parsed.status}, type ${parsed.headers['content-type']})
    console.log(`body: ${parsed.body}`)
