Enterprise Grade

System Architecture & SQL

Need a database schema? Or a system design for a microservices app? Lummie can plan entire architectures and generate the SQL migrations to match.

CREATE TABLE users ( id UUID PRIMARY KEY DEFAULT uuid_generate_v4(), email VARCHAR(255) UNIQUE NOT NULL, created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW() );

Before vs After

Messy & Buggy

var x = [1,2,3];

for(i=0;i<x.length;i++) {

  console.log(x[i])

}

// Error: i is not defined

Clean & Typed

const numbers: number[] = [1, 2, 3];

numbers.forEach((num) => {

  console.log(num);

});
