Aurora Deep Slice, Merge and Append

Tool for slicing, merging and appending to Aurora configuration objects.

Example

const util = require('util')
const { slice, merge } = require('aurora-deep-slice-merge');

let configPage1 = { meta: { title: 'Blabla' },
  app:
   { type: 'awesome-app', options:
      { modules:
         [ { type: 'awesome-module', options: { a: 5 } },
           { type: 'awesome-module', options: { b: 10 } },
           { type: 'awesome-hom', options: {
             modules:
              [ { type: 'awesome-module', options: { c: 15 } } ] } } ] } } }

let configPage2 = { meta: { title: 'Blabla' },
  app:
   { type: 'awesome-app', options:
      { modules:
         [ null,
           null,
           { type: 'awesome-hom', options:
             { modules:
              [ null,
                { type: 'awesome-module', options: { d: 20 } },
                { type: 'awesome-hom', options: {
                  modules:
                   [ { type: 'awesome-module', options: { e: 25 } },
                     { type: 'awesome-module', options: { f: 30 } } ] } } ] } } ] } } }

console.log(util.inspect(merge(configPage1, configPage2)));

output:

{ meta: { title: 'Blabla' },
  app:
   { type: 'awesome-app', options:
      { modules:
         [ { type: 'awesome-module', options: { a: 5 } },
           { type: 'awesome-module', options: { b: 10 } },
           { type: 'awesome-hom', options:
              { modules:
                 [ { type: 'awesome-module', options: { c: 15 } },
                   { type: 'awesome-module', options: { d: 20 } },
                   { type: 'awesome-hom', options:
                      { modules:
                         [ { type: 'awesome-module', options: { e: 25 } },
                           { type: 'awesome-module', options: { f: 30 } } ] } } ] } } ] } } }

Append a list of modules to an Aurora configs (shallow).

Example

const util = require('util')
const { append } = require('aurora-deep-slice-merge');

let config = { meta: { title: 'Blabla' },
  app:
   { type: 'awesome-app', options:
      { modules:
         [ { type: 'awesome-module', options: { a: 5 } },
           { type: 'awesome-module', options: { b: 10 } } ] } } }

let modulesToAppend = [
  { type: 'awesome-hom', options:
    { modules:
      [ { type: 'awesome-module', options: { c: 15 } },
        { type: 'awesome-module', options: { d: 20 } },
        { type: 'awesome-hom', options:
          { modules:
            [ { type: 'awesome-module', options: { e: 25 } },
              { type: 'awesome-module', options: { f: 30 } } ] } } ] } } ]

console.log(util.inspect(append(config, modulesToAppend)));

{ meta: { title: 'Blabla' },
  app:
   { type: 'awesome-app', options:
      { modules:
         [ { type: 'awesome-module', options: { a: 5 } },
           { type: 'awesome-module', options: { b: 10 } },
           { type: 'awesome-hom', options:
              { modules:
                 [ { type: 'awesome-module', options: { c: 15 } },
                   { type: 'awesome-module', options: { d: 20 } },
                   { type: 'awesome-hom', options:
                      { modules:
                         [ { type: 'awesome-module', options: { e: 25 } },
                           { type: 'awesome-module', options: { f: 30 } } ] } } ] } } ] } } }
