Slugged models for Objection.js

This plugin will automatically generate slugs for your model based on a source field and a slug field. It will also generate unique slugs by checking to see if the slug already exists in the model's table.

Installation

npm install objection-slugify --save

Usage

// Import the plugin.
const slugifyPlugin = require('objection-slugify');
const { Model } = require('objection');

class Post extends slugify(Model) {
  // ...code

  title: 'How to Fry an Egg'
});

console.log(post.slug);
// how-to-fry-an-egg
