Build Status

GCloudex

Google Cloud for Elixir. Friendly set of wrappers for Google Cloud Platform services' API's.

Features

  • Minimal configuration and dependencies
  • Friendly way to use Google Cloud services' API's
  • Function names and signatures closely mimic their REST counterparts
  • HTTP requests sent using the popular HTTPoison app providing familiar HTTP responses
  • Easy to extend

Installation and Configuration

GCloudex uses HTTPoison for the HTTP requests, Poison for JSON encoding/decoding and Friendly for XML parsing. The Google Authorization Tokens are retrieved using Goth. The JSON API's for the various Google Cloud services are used whenever possible or available.

  1. Add gcloudex to your list of dependencies in mix.exs:

    def deps do
      [{:gcloudex, git: "git@github.com:sashaafm/gcloudex.git"}]
    end
    
  2. Ensure gcloudex is started before your application:

    def application do
      [applications: [:gcloudex]]
    end
    

Then go to the Google Cloud's website and download the credentials file for your Google Project.

Put that file in your application's config folder and rename the file to creds.json (or whatever name you prefer). This file will be used to authenticate the requests. Be sure to add it to your .gitignore file in case you're uploading to a public repository.

Finally put inside the config file you want (like dev.exs) the following line:

config :goth,
  json: "config/<filename>.json" |> Path.expand |> File.read!

That's all you need to use GCloudex.

Usages Examples

Cloud Storage:

GCloudex.CloudStorage.Client.list_buckets # => {:ok, %HTTPoison.Response{body: ..., status_code: 200}}
GCloudex.CloudStorage.CLient.put_object "bucket_name", "this_file.txt" # => {:ok, %HTTPoison.Response{body: ..., status_code: 200}}

Cloud SQL:

GCloudex.CloudSQL.Client.list_databases "instance_name" # => {:ok, %HTTPoison.Response{body: ...,status_code: 200}}
GCloudex.CloudSQL.Client-insert_databaes "instance_name", "db_name" # => {:ok, %HTTPoison.Response{body: ...,status_code: 200}}

Cloud Speech:

body = """
{
  "audio": {
    "uri": "gs://foo/bar.flac"
  },
  "config": {
    "encoding":"flac",
    "sampleRate": 48000,
    "languageCode":"en-US",
    "maxAlternatives": 1
  }
}
"""

iex> GCloudex.CloudSpeech.Client.longrunningrecognize(body)
{:ok,
 %HTTPoison.Response{body: "{\n  \"name\": \"1234567890\"\n}\n",
  headers: [...], status_code: 200}}

iex> GCloudex.CloudSpeech.Client.get("1234567890")
{:ok,
 %HTTPoison.Response{body: "{\n  \"name\": \"1234567890\",\n  \"metadata\": {...
