Dimer Context

> Runtime context for dimer

[![travis-image]][travis-url]
[![npm-image]][npm-url]

Dimer is a combination of several small modules, joining together to build the final app. Passing user options from top-level to all these libraries can be daunting and hence a context is used to read and write runtime values.

At the lowest level, context starts with the basePath and new values are added, as it is passed through several modules.
Also you can debug the actions taken on the context by defining DEBUG environment variable.

``shell
DEBUG=dimer:context node yourapp.js
`

Installation

`js
npm i @dimerapp/context

Yarn


yarn add @dimerapp/context
`

Usage

`js
const Context = require('@dimerapp/context')
const ctx = new Context(__dirname)

// later pass around other libs
const config = new (require('@dimerapp/config-parser'))(ctx)
const store = new (require('@dimerapp/datastore'))(ctx)
`

API

The following methods are available to read/write to the context.

##### constructor(basePath, [distPath = 'dist'])

`js
const ctx = new Context(__dirname, 'dist')
`

#### set(lib, key, value)
The lib option is required for debugging, so that context can log name of the library, which has mutated the state.

`js
ctx.set('config-parser', 'config', value)
`

#### get(key)
Get value for a given key. We recommend you not to mutate the return value and instead transform it.

`js
ctx.get('config')
`

#### remove(key)
Remove value for a given key

`js
ctx.remove('config')
``
