Detects when a new file is different than an existing file and prompts the user for action.

Install

Install with npm:

$ npm install --save conflicts

Usage

const Conflicts = require('conflicts');
const conflicts = new Conflicts();

API

Conflicts

Create an instance of Conflicts with the given options and optional Vinyl constructor.

Params

• options {Object}
• File {Function}: Optionally pass a vinyl contructor, otherwise the default File class is used.
• returns {Conflicts}: Returns an instance of Conflicts.

Example

const Conflicts = require('conflicts');
const conflicts = new Conflicts({}, require('vinyl'));

.detectFile

Compares an existing (old) file to a new proposed file, then prompts for an action if the files are not equal. If the contents of both files is identical, no action is taken, otherwise you will be prompted to choose the action to take. See the unit tests for examples of how to skip prompts.

Params

• proposedFile {Object}: New file.
• existingFile {Object}: Existing file.
• options {Object}
• returns {Promise}: Returns a promise with the action that was taken.

Example

conflicts.detect(fileA, fileB)
  .then(action => console.log('Action taken:', action))
  .catch(console.error)

.detectFile

Same as .detect, except the second argument is a string to an existing file on the file system.

Params

• proposed {Object}: New file.
• existingPath {Object}: File path to existing file.
• options {Object}
• returns {Promise}: Returns a promise with the action that was taken.

Example

conflicts.detectFile(file, 'path/to/file.txt')
  .then(action => console.log('Action taken:', action))
  .catch(console.error)

.files

Runs detect on an array of "proposed" files.

Params

• files {Array}: Array of file objects.
• options {Object}
• returns {Array}

Example

conflicts.files([fileA, fileB, fileC])
  .then(action => console.log('Action taken:', action))
  .catch(console.error)

.diffFiles

Takes an array of "proposed" files, and returns an array of strings, where each string represents a diff of the proposed file's contents versus an existing file's contents.

Params

• files {Array}
• options {Object}
• returns {Array}

Example

conflicts.diffFiles([fileA, fileB, fileC])
  .then(diffs => {
    diffs.forEach(diff => console.log(diff));
  })
  .catch(console.error)

.isEqual

Returns true if an fileA (existing/old) file appears to be identical to a fileB (proposed/new) file.

Params

• proposed {Object}: vinyl file representing a proposed (new) file
• existing {Object}: vinyl file representing an existing (old) file
• options {Object}
• returns {Boolean}

Example

console.log(conflicts.isEqual(fileA, fileB));
