runtime-migrate

Makes mongo database migrations at runtime with versioning.

Install

npm install --save runtime-migrate

Usage

runtime-migrate will run scripts on a mongo database if they have not been executed before when your app starts, to achieve this follow the steps below.

Create a schema

var mongoose = require('mongoose'),
    Schema = mongoose.Schema;

var exampleSchema = new Schema({
    name: String,
    description: String,
});

Create a migration script

var migrations = [{
    version: "1.0.0",
    description: "Initial setup",
    script: function(done) {
        exampleSchema.insertMany([{
            "name": "Object one",
            "description": "Added on first version"
        }]).then(done);
    }
}];

Execute the migrations at runtime

var migrator = require('runtime-migrate');

// connect to mongo
mongoose.connect("mongodb://localhost/exampleDB");

// execute the migrations
migrator.migrate(migrations, function(result) {
    console.log("Database migration result: %s", result)
});
