Memcached Plugin for Godspeed

Link to Plugin Source Code

The Godspeed mem-cache plugin provides caching interfaces, allowing developers to seamlessly use in-memory cache within the Godspeed framework.

How to add mem-cache plugin in your project​

  • Create a godspeed project from the CLI and add the mem-cache plugin
godspeed plugin add @godspeedsystems/plugins-mem-cache-as-datasource

You will find two files in your project related to the plugin at src/datasources/types/mem-cache.ts and src/datasources/mem-cache.yaml.

type: mem-cache

Sample Usage​

Create two events and two event handler workflows for each event, by the name helloworld2 and helloworld3 respectively.

Events​

http.get./helloworld2:
 fn: helloworld2

http.get./helloworld3:
 fn: helloworld3

Plugin Components​

The plugin consists of the following key components:

1. DataSource Class​

  • This class extends GSCachingDatasource, a base class provided by the Godspeed framework for creating data sources.

  • It initializes a client which provides an object to use as in-memory cache.

  • The set method is used to set the key and value of the cache.

  • The get method is used to get value from the cache.

  • The del method is used to delete value from the cache.

2. Constants​

  • SourceType: A constant representing the source type of the plugin, which is 'DS' (data source).

  • Type: A constant representing the loader file of the plugin. The final loader file will be located in the 'types' directory and named ${Type.js}, where Type is 'mem-cache' in this case.

  • CONFIG_FILE_NAME: In the context of a data source, this constant also serves as the data source name. In this plugin, it is set to 'mem-cache'.

The Godspeed mem-cache Plugin is a valuable addition to the Godspeed framework, providing a standardized way to use in-memory cache.
