You're ready for this tutorial if you've got the following:

A FreeClimb account
A registered application
A configured FreeClimb Number
Your tools and language installed


Node.js

Using the FreeClimb SDK an asynchronous request to stream a given recording can be initiated (recordingId not provided for this example). Successful invocation will return a Node readable stream which may be read or redirected as needed.

Create your package.json file and save in the root directory of your project:

{
  "name": "node-stream-a-recording-tutorial",
  "version": "1.0.0",
  "dependencies": {
    "@freeclimb/sdk": "^1.0.0",
    "dotenv": "^8.1.0"
  }
}

Install the package by running the following in the command line/terminal:

yarn install

Example code:

// Imports and setup
require('dotenv').config()
const freeclimbSDK = require('@freeclimb/sdk')
const accountId = process.env.ACCOUNT_ID
const apiKey = process.env.API_KEY
const freeclimb = freeclimbSDK(accountId, apiKey)
// Your account ID & API key can be found under API credentials on the FreeClimb Dashboard

freeclimb.api.recordings.stream(recordingId).then(stream => {
  stream.on('data', chunk => {
    console.log(`Received ${chunk.length} bytes of data.`)
  })
  stream.on('end', () => {
    console.log('no more data!')
  })
}).catch(err => {
  // Handle Errors
})

Java

To initiate any interaction with FreeClimb a FreeClimbClient object must be created. Using the RecordingsRequester created upon successful creation of the FreeClimbClient a synchronous request to stream a given recording can be initiated. Successful invocation will return a KnownSizeInputStream which may be read or redirected as needed. The KnownSizeInputStream is a special variant on the standard Java InputStream that exists in the FreeClimb SDK where the size of the underlying data is known.

Create your build.gradle file and save it to the root directory in your project:

/*
 * This file was generated by the Gradle 'init' task.
 *
 * This is a general purpose Gradle build.
 * Learn how to create Gradle builds at https://guides.gradle.org/creating-new-gradle-builds
 */

buildscript {
    repositories {
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'

repositories {
    mavenCentral()
    maven { url 'https://jitpack.io' }
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    testCompile "junit:junit"
    compile 'com.github.FreeClimbAPI:FreeClimb-Java-SDK:3.0.0'
}

jar {
    manifest {
        attributes 'Main-Class': 'stream_a_recording.StreamRecording'
    }
}

sourceSets {
    main {
        java {
            srcDirs = ['src'] // changed line
        }
    }
}

Build the file by running the following in your terminal/command line:

gradle build

Example code:

import com.vailsys.freeclimb.api.FreeClimbClient;
import com.vailsys.freeclimb.KnownSizeInputStream;
import com.vailsys.freeclimb.api.FreeClimbException;

FreeClimbClient client;
KnownSizeInputStream stream;
 
try {
  // Create FreeClimbClient object
  // accountId & apiKey can be found under API credentials on the FreeClimb Dashboard
  client = new FreeClimbClient(accountId, apiKey);
 
  /*
   * Make the request for the recording. Receiving an InputStream in
   * return which can be used to stream the recording.
   */
  stream = client.recordings.stream(recordingId);
}
catch(FreeClimbException pe) {
  System.out.println(pe.getMessage());
}

C#

To initiate any interaction with FreeClimb a FreeClimbClient object must be created. Using the RecordingsRequester created upon successful creation of the FreeClimbClient a synchronous request to stream a given recording can be initiated. Successful invocation will return an IO stream which may be read or redirected as needed. In the sample the result is streamed via a FileStreamResult action.

Imports used:

using com.freeclimb.api;

Example code:

try {
  // Create FreeClimbClient object
  FreeClimbClient client = new FreeClimbClient(FreeClimbAccountId, FreeClimbApiKey);

  // Invoke get method with AudioReturn format of Stream to obtain IO stream of audio
  Stream stream = client.getRecordingsRequester.stream(RecordingId);
}
catch (FreeClimbException ex) {
  // Exception throw upon failure
}
