    REST API cli

    There are some patterns that I prefer when writing a REST API using node, and this module is just a simple cli that scaffolds out a basic example of those patterns.

    Modules Used:

    • restify - for serving the RESTful endpoints
    • pg - for connecting to a PostgreSQL database
    • knex - for writing database-agnostic queries in js
    • morgan - for logging
    • lib - resuable pieces that I wanted to keep with the source, but could also be required without doing relative paths like require('../../../conn')


    • dotenv - to keep config outside of the code
    • eslint - set up using 'standard' style
    • nodemon - to watch for file changes during development
    • pre-commit - commits fail when npm test fails
    • sqlite3 - used as the db during development

    Getting Started

    For development, you just need node v4 OR v6 and lastest npm, which you cant get by running npm i -g npm.

    Creating the example project:

    • npm i -g rest-api-cli
    • rest-api-cli my-new-project
    • cd my-new-project
    • npm i
    • npm run db
    • npm start

    You should be able to hit localhost:8079/people and get some results


    The entry point of the application is src/index.js, which sets up some restify plugins, logging, routes, and the server. A line of interest is:


    The queries function is the export of the src/queries/index.js file. This file is where we pass out restify server into various files containing routes.

    module.exports = app => {
      // require your queries here

    So that takes us to our src/queries/people.js and src/queries/places.js, where the real action is happening.

    The places file takes advantage of some defaults craeted for calling CRUD operations that require no relational joins. It uses the queries already written in lib/query.js.

    All we have to do is export a function that creates the routes, and pass our queries as the callback.

    const db = require('lib/db-conn')
    const query = require('lib/query')
    const table = 'places'
    const columns = [
    const places = query(db, table, columns)
    module.exports = app => {
      app.get('/places', places.index)
      app.get('/places/:id', places.find)'/places', places.create)
      app.put('/places/:id', places.update)
      app.del('/places/:id', places.destroy)

    If some joins are needed, then just write the callback functions, like in src/queries/people.js:

    const table = 'people'
    const columns = [
    const people = query(db, table, columns)
    // Write our own queries for the GET methods,
    // so we can add some joins
    function index (req, res, next) {
      db(`${table} AS p`)
        .leftJoin('places AS pl', 'p.place_id', '')
        .then(rows => res.send(rows))
        .then(() => next())
    function find (req, res, next) {
      db(`${table} AS p`)
        .leftJoin('places AS pl', 'p.place_id', '')
        .then(rows => res.send(rows))
        .then(() => next())
    module.exports = app => {
      app.get('/people', index)
      app.get('/people/:id', find)'/people', people.create)
      app.put('/people/:id', people.update)
      app.del('/people/:id', people.destroy)
