yepql - Javascript & SQL rethought

Yepql is a javascript library for using SQL.

It is heavily inspired by yesql

Install

$ yarn add yepql

Driver

You'll need a database driver

Database	npm install --save package
PostgreSQL	pg
SQL Server	mssql

Use

-- get-users-by-id.sql

select *
from Users
where Users.ID = @ID

// db.js
var mssql = require("mssql");
var yepql = require("yepql")(mssql);

var getUsersByID = yepql.makeQuery("./get-users-by-id.sql");

module.exports = { getUsersByID };

// env.js
module.exports = {
  connectionString: process.env.CONNECTION_STRING || "Server=localhost,1433;Database=database;User Id=username;Password=password;Encrypt=true";
}

var db = require("./db");
var env = require("./env");

db
.getUsersByID(env.connectionString, { ID: 1 })
.then((rows) => {
  /*
    rows === [{
      ID: 1,
      Username: 'username',
      Email: 'email@example.com',
      ...
    }]
  */
})
.catch(/* handle error */)

Have a lot of sql files?

-- sql/getUsersByID.sql

select *
from Users
where Users.ID = @ID

-- sql/getUsersByEmail.sql

select *
from Users
where Users.Email = @Email

// db.js
var yepql = require("yepql");

var queries = yepql.makeQueries("./sql");

/*
  queries === {
    getUsersByID: function(connectionString, params),
    getUsersByEmail: function(connectionString, params)
  }
*/

module.exports = queries;
