Mongoose URL Slugs
A simple URL based slug generator for mongoose models.
Installation
$ npm install mongoose-url-slugs
V1 Breaking Changes
Option keys are now all Camel case, as opposed to previously.
What is a Slug?
A slug is a human-readable unique identifier that can be used in a URL instead of an ID or hash. This is common in content sites where the title of the article is "slugified" to turn this ugly URL
http://example.com/a12Qv09b4
into this pretty one
http://example.com/your-article-title-here
How Slugs are Formatted
When supplied with a string, the following steps are taken to transform it into a slug.
- Accented characters are converted to regular equivalent characters.
- Converted to lower case
- All punctuation is removed
- All spaces are replaced with dashes
- Add a number to the end if the slug isn't unique (eg:
my-cool-slug
and my-cool-slug-2
)
Example Usage
Example 1: Using default options and using 2 fields for slug generation.
var mongoose = require('mongoose'),
Schema = mongoose.Schema,
URLSlugs = require('mongoose-url-slugs');
var testSchema = new Schema({
first_name: {type: String, default: '', trim: true},
last_name: {type: String, default: '', trim: true},
rev: {type: String, default: '', trim: true}
});
testSchema.plugin(URLSlugs('first_name last_name'));
Example 2: Using 'myslug' key for storing slug.
var mongoose = require('mongoose'),
Schema = mongoose.Schema,
URLSlugs = require('mongoose-url-slugs');
var testSchema = new Schema({
first_name: {type: String, default: '', trim: true},
last_name: {type: String, default: '', trim: true},
rev: {type: String, default: '', trim: true}
});
testSchema.plugin(URLSlugs('first_name last_name', {field: 'myslug'}));
