Installation

The best way to install it is using npm

npm install mongoose-slug-maker --save

Loading

var slug = require('mongoose-slug-maker');

Initialization

var mongoose = require('mongoose');
mongoose.plugin(slug);

Usage

This plugin is based on the idea of using the mongoose schema as the way to check the use of slug fields.

The plugin checks and updates automatically the slug field with the correct slug.

Basic Usage

If you only want to create the slug based on a simple field.

var mongoose = require('mongoose'),
    slug = require('mongoose-slug-maker'),
    mongoose.plugin(slug),
    Schema = mongoose.Schema,
    schema = new Schema({
        title: String,
        slug: { type: String, slug: "title" }
});

Multiple slug fields

You can add as many slug fields as you wish

var mongoose = require('mongoose'),
    slug = require('mongoose-slug-maker'),
    mongoose.plugin(slug),
    Schema = mongoose.Schema,
    schema = new Schema({
        title: String,
        subtitle: String,
        slug: { type: String, slug: "title" },
        slug2: { type: String, slug: "title" },
        slug3: { type: String, slug: "subtitle" }
});

Multiple fields to create the slug

If you want, you can use more than one field in order to create a new slug field.

var mongoose = require('mongoose'),
    slug = require('mongoose-slug-maker'),
    mongoose.plugin(slug),
    Schema = mongoose.Schema,
    schema = new Schema({
        title: String,
        subtitle: String,
        slug: { type: String, slug: ["title", "subtitle"] }
});

Unique slug field

To create a unique slug field, you must only add add the unique: true parameter in the path (also, this way the default mongo unique index gets created)

var mongoose = require('mongoose'),
    slug = require('mongoose-slug-maker'),
    mongoose.plugin(slug),
    Schema = mongoose.Schema,
    schema = new Schema({
        title: String,
        subtitle: String,
        slug: { type: String, slug: ["title", "subtitle"], unique: true }
});

If unique is set, the plugin searches in the mongo database, and if the slug already exists in the collection, it appends to the slug a separator (default: "-") and a random string (generated with the shortid module).

example random

mongoose.model('Resource').create({
    title: 'Am I wrong, fallin\' in love with you!',
    subtitle: "tell me am I wrong, well, fallin' in love with you"
}) // slug -> 'am-i-wrong-fallin-in-love-with-you'

mongoose.model('Resource').create({
    title: 'Am I wrong, fallin\' in love with you!',
    subtitle: "tell me am I wrong, well, fallin' in love with you"
}) // slug -> 'am-i-wrong-fallin-in-love-with-you-Nyiy4wW9l'

mongoose.model('Resource').create({
    title: 'Am I wrong, fallin\' in love with you!',
    subtitle: "tell me am I wrong, well, fallin' in love with you"
}) // slug -> 'am-i-wrong-fallin-in-love-with-you-NJeskEPb5e'

Alternatively you can modify this behaviour and instead of appending a random string, an incremental counter will be used. For that to happen, you must use the parameter slug_padding_size specifying the total length of the counter:

example counter

var mongoose = require('mongoose'),
    slug = require('mongoose-slug-maker'),
    mongoose.plugin(slug),
    Schema = mongoose.Schema,
    schema = new Schema({
        title: String,
        subtitle: String,
        slug: { type: String, slug: ["title", "subtitle"], slug_padding_size: 4,  unique: true }
});

mongoose.model('Resource').create({
    title: 'Am I wrong, fallin\' in love with you!',
    subtitle: "tell me am I wrong, well, fallin' in love with you"
}) // slug -> 'am-i-wrong-fallin-in-love-with-you'

mongoose.model('Resource').create({
    title: 'سلام دنیا',
    subtitle: "لورم اپسون با تولید سادگی"
}) // slug -> 'سلام-دنیا'



mongoose.model('Resource').create({
    title: 'Am I wrong, fallin\' in love with you!',
    subtitle: "tell me am I wrong, well, fallin' in love with you"
}) // slug -> 'am-i-wrong-fallin-in-love-with-you-0001'

mongoose.model('Resource').create({
    title: 'Am I wrong, fallin\' in love with you!',
    subtitle: "tell me am I wrong, well, fallin' in love with you"
}) // slug -> 'am-i-wrong-fallin-in-love-with-you-0002'

Choose your own options

You can change any options adding to the plugin

var mongoose = require('mongoose'),
    slug = require('mongoose-slug-maker'),
    options = {
        separator: "-",
        lang: "en",
        truncate: 120
    },
    mongoose.plugin(slug, options),
    Schema = mongoose.Schema,
    schema = new Schema({
        title: String,
        subtitle: String,
        slug: { type: String, slug: ["title", "subtitle"], unique: true }
});
