Slugs can be replacement of post id of your blog . Using title or a string we can generate clean url slugs. It can be used with Mongoose(Mongoose is a npm package driver for NoSQL MongoDB ) Model or any Model class. The slugify npm package is ready to serve our requirement. Install the package using
npm i slugify --save
Here is our Mongoose Post Model Schema definition
const mongoose = require("mongoose");
const slugify=require('slugify')
const postSchema = new mongoose.Schema({
title: { type: String, required: true },
excerpt: { type: String },
slug: { type: String,required:true,unique:true },
);
postSchema.pre('validate',function(next){
if(this.title){
this.slug=slugify(this.title,{lower:true,strict:true})
}
next()
})
module.exports = mongoose.model("Post", postSchema);
Validate and Generate slugs automatically
The postSchema.pre(‘validate’,function(next) can be used to validate the model fields and then we can auto generate neat slug based on the title and then store the slug into the model.
Slugify also remove special character ,semicolon ect from the string passed to it. These option are passed as parameters ({ })
The pre validation is invoked when a new object is created and save it to the database / document collection.
The slugify is handy tool when we are dealing with blog app or discussion forums.
