Start a CRUD API quickly using Node, Express & Postgres.
Serves four requests (get, post, put, delete) from one page with a separate function for each.
All code can be edited and replaced to fit the needs of the project being built.
Dependencies
We use express to serve the API, body-parser to parse responses, postgres for the database, knex as the query engine, dotenv to protect environment variables, helmut to add proper headers, cors to prevent/allow XSS, morgan as our logger, and nodemon as a dev dependency to watch for changes.
All dependencies are included in the cloned project.
1. Clone the repo
git clone https://github.com/olinations/crud-starter-api.git
2. CD into the project
cd crud-starter-api
3. Install dependencies
npm install
4. Start Postgres
brew services start postgresql
Note: You can use Postgres or MYSQL. We are using Postgres. If you would like to use MYSQL instead of Postgres you will need to npm uninstall pg and npm install mysql. Then edit the above command to start MYSQL started on your computer.
5. Create a database
Change the database name to whatever you would like to name the database. Be sure to also change the database name in server.js to whatever you name the database.
createdb crud-starter-api
6. Create a database table
Open pSequel and run the following command. Change the table name to whatever you would like to name the table.
CREATE TABLE testtable1 (
id serial PRIMARY KEY,
first VARCHAR(100),
last VARCHAR(100),
email text UNIQUE NOT NULL,
phone VARCHAR(100),
location VARCHAR(100),
hobby VARCHAR(100),
added TIMESTAMP NOT NULL
);
View the repository for the frontend that goes along with this API. It uses React and Bootstrap to display a responsive data table. It serves as the perfect starter for the frontend, however, you can use any frontend to access this API.
This is just a starter kit for getting a basic API up and running. Feel free to change any and every thing about it. A production ready app with more API requests and routes should undoubtedly have much of the code abstracted to different files and folders. This repo simply eliminates the need for a dev to do a bunch of research on how to get an API setup, secure, and running in a professional manner.
An important piece that is missing from this API is an authentication API. In that case it is recommended to install bCrypt for password hashing and authentication. Then, more routes should be created for registering, logging in and logging out users. There should also be a scheme for keeping users logged in. The suggested method for persisting logins would be to use JWT for token creation, Redis to store tokens in server memory, and localStorage to save tokens on the frontend. The tokens stored in localStorage will be sent back to the API via authorization headers for protected requests and would need to be verified by the server.
