Shared tools used in ClassyPay-related projects
npm install classy-pay-coreThe classy-pay-core NPM module contains a set of reusable common tools used in ClassyPay-related projects. There are a few pieces of functionality included, most notably:
- A plugin-based, lazily loaded configuration "dictionary" (implemented by the ``Config` class). The intent here is to be able to provide a bunch of different running node applications with a common set of lazily-populated global state, e.g. configuration that's shared between applications. A sample implementation (`aws/AWSConfig`) and set of plugins (inside `DataSources/`) is included as well (though probably minimally useful to anyone outside of Classy).
- A client that can be used to authenticate with / converse with the ClassyPay APIs (`PayClient`).
- A set of general purpose utilities:
- `Lock`: a simple mutex`
- Once`: a JavaScript implementation of `pthread_once`
- callbackWrapper`: code which allows you to perform promise-based operations (or async/await-based) from within a callback
- Some other random utilities
To load parts of the module, first load classy-pay-core as a whole, and then call `submodule` on the default export, like so:
`json``
const Once = require('classy-pay-core').submodule('utils/Once');
