Build and Test

Saltcorn is an extensible open source no-code database application builder. Use it to build web applications based on relational data with flexible views, datatypes and layouts.

This repository contains the core codebase, including the code necessary to self host an instance and to host a multitenant instance.

Trying out Saltcorn

A multitenant instance of Saltcorn is running at, and you can create a new database under a subdomain at this service is free but there are no guarantees about the security or availability of your application or the information you are storing. This service should only be used to explore the capabilities of saltcorn.

For self hosting, a 1 GB virtual private server is sufficient to run Saltcorn unless you expect high traffic volumes. Installation instructions are given below. If hosting on DigitalOcean, which offers a 1GB virtual machine for $5 per month, please consider using my referral code which will give you $100 credit over 60 days.


Saltcorn is using PostgreSQL, node.js, node-postgres, express, live-plugin-manager, craft.js, jQuery-Menu-Editor and other awesome free and open source projects.

Quickstart with Docker

You can run a local instance for quick test by running the following command

cd ./deploy/examples/test && docker-compose up -d

and then point your browser to http://localhost:3000

Install from packages

Instructions have been tested on Ubuntu 20.04 on a 1GB VM.


npm install -g @saltcorn/cli && saltcorn setup

Installing node and npm

For a recent version (v14) of Node.js:

wget -qO - | sudo -E bash -
sudo apt-get install -y nodejs libpq-dev build-essential python-is-python3

Install saltcorn

npm install -g @saltcorn/cli

If this fails, you may need to tell npm to disregard file permissions during compilation:

npm install -g @saltcorn/cli --unsafe

Setup (automated)

if you are

, create a user with sudo and switch to that user:
adduser saltcorn
adduser saltcorn sudo
su saltcorn
mkdir -p ~/.config/

then run

saltcorn setup
and follow instructions

Setup (manual)

Skip this section if you ran

saltcorn setup
  1. Install PostgreSQL:
    sudo apt install postgresql postgresql-client
  2. Either,
  • Create a JSON file

    in your XDG config directory (on Ubuntu this is normally \$HOME/.config) with these values:
    • host
      : address of PostgreSQL server
    • port
      : port of PostgreSQL server
    • database
      : PostgreSQL database
    • user
      : PostgreSQL user name
    • password
      : PostgreSQL user password
    • session_secret
      : Saltcorb session secret
    • multi_tenant
      : run as multi-tenant (true/false)

    For example:



  • Set environment variables.

    (defaults to
    ), and either


saltcorn serve

Server install

nginx install and setup

Install nginx:

sudo apt install nginx

create a file

, replacing
with your domain, with these contents:
server {
    listen 80;
    location / {
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;

link this file to the


sudo ln -s /etc/nginx/sites-available/ /etc/nginx/sites-enabled/

reload nginx:

sudo service nginx reload

now run saltcorn:

sudo -u saltcorn saltcorn serve


saltcorn serve
if you didn't created a new user.

Check whether you can access your new site in the browser.

Install saltcorn as a service

Installing saltcorn as a service will mean it runs in the background and restarts automatically if the system reboots.

create a file

with these contents:

[Service] Type=simple User=saltcorn WorkingDirectory=/home/saltcorn ExecStart=/usr/bin/saltcorn serve Restart=always



sudo systemctl daemon-reload
sudo systemctl start saltcorn
sudo systemctl enable saltcorn

SSL certificate

Use cloudflare or lets encrypt to get a free SSL certificate (for https).

Install from source (for saltcorn developers)

Installing node and npm on Ubuntu

sudo apt install nodejs npm libpq-dev

will give you a usable version. For a more recent version (v14) of Node.js:

wget -qO - | sudo -E bash -
sudo apt-get install -y nodejs libpq-dev

Prepare Node

assuming you have cloned this repository to \$HOME/saltcorn (otherwise adjust PATH)

npm config set prefix ~/.local
echo 'export PATH=$HOME/saltcorn/packages/saltcorn-cli/bin:$HOME/.local/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

Install packages

install lerna with

npm install -g lerna


lerna bootstrap

to install everything. If successful, you should now be able to run

in your shell


Development tips


we use prettier:

npm install -g prettier

to format code:

git ls-files | grep -v builder_bundle | xargs prettier --write

Run this before every pull request.

dev server

nodemon packages/saltcorn-cli/bin/saltcorn serve

to also watch a local module

nodemon --watch ../saltcorn-kanban/ packages/saltcorn-cli/bin/saltcorn serve

React rebuild on save



git ls-files | entr npm run builddev
