Install

Install with npm:

$ npm i answer-store --save

Usage

var answer = require('answer-store');

What does this do?

With project generators and build systems it's fairly common to prompt the user for information that is needed to complete the build or generate the project.

This library makes it easy to:

1. Persist the answers to the file system
2. Store values based on the current working directory
3. Store defaults that can be used regardless of the directory

How this works

• An answer is stored based on the current working directory, and the currently defined locale.
• A default answer may be defined for each locale

See the API docs for information about setting and getting stores values.

Example

var answer = new Answer('project-name');
answer.set('foo');

Results in the following object being written to project-name.json at '/Users/jonschlinkert/answers/project-name.json':

{
  cache:
   { dest: '/Users/jonschlinkert/answers',
+     path: '/Users/jonschlinkert/answers/project-name.json',
     cwd: '/Users/jonschlinkert/dev/answer-store' },
  options: {},
  name: 'project-name',
  data: { 
    en: { 
      '/Users/jonschlinkert/dev/answer-store': 'foo' 
    }
  }
}

locales

If the question has been answered for multiple locales, the object would something like this:

{
  cache:
   { dest: '/Users/jonschlinkert/answers',
     path: '/Users/jonschlinkert/answers/project-name.json',
     cwd: '/Users/jonschlinkert/dev/answer-store' },
  options: {},
  name: 'project-name',
+  data: { 
+    en: { '/Users/jonschlinkert/dev/answer-store': 'foo' },
+    es: { '/Users/jonschlinkert/dev/answer-store': 'bar' },
+    fr: { '/Users/jonschlinkert/dev/answer-store': 'baz' }
+  }
}

directories

When the question has been answered from different directories, the object might look something like this:

{
  cache:
   { dest: '/Users/jonschlinkert/answers',
     path: '/Users/jonschlinkert/answers/project-name.json',
     cwd: '/Users/jonschlinkert/dev/answer-store' },
  options: {},
  name: 'project-name',
  data: { 
+    en: { 
+      '/Users/jonschlinkert/dev/answer-store/1': 'foo1',
+      '/Users/jonschlinkert/dev/answer-store/2': 'foo2',
+      '/Users/jonschlinkert/dev/answer-store/3': 'foo3' 
+    }
  }
}

defaults

A default value may be stored for each locale:

{
  cache:
   { dest: '/Users/jonschlinkert/answers',
     path: '/Users/jonschlinkert/answers/project-name.json',
     cwd: '/Users/jonschlinkert/dev/answer-store' },
  options: {},
  name: 'project-name',
  data: { 
+    default: 'foo',
    en: { 
      '/Users/jonschlinkert/dev/answer-store/1': 'foo1',
      '/Users/jonschlinkert/dev/answer-store/2': 'foo2',
      '/Users/jonschlinkert/dev/answer-store/3': 'foo3' 
    }
  }
}

What else?

Module dependencies are lazily required, so initialization is fast!
