LAAS is an abbreviation for LevelDB as a service. LevelDB is an implementation of a log structured merge tree (LSMTree) provided by Google. This data structure aimed at providing a high write throughput. When attempting to use LevelDB, I found it difficult to track down supported libraries in different languages. Additionally, the fact that it’s labeled as a database and doesn’t provide a service was troublesome. I wrote LAAS to make the adoption of LevelDB easy for any language. It does this by introducing a RESTful API to the underlying functionality. HTTP request libraries are a dime a dozen, which drove the choice for a RESTful implementation.

Getting Started

The easiest way to get started with LAAS is to install it globally with NPM.

{% highlight bash %} npm install -g laas {% endhighlight %}

After executing this command, you should have access to the laas command. This command provides a range of functionality, the core of which is to manage the service layer. By executing laas start, you can start the service running in the background on port 6931. You can verify that the service is running by executing the laas status command.
