* access to a [PostGIS](https://postgis.net) server
* [Node and npm](https://nodejs.org/en/download/)
## PostgreSQL user
User should **only** have SELECT right on tables. You can create one as follows:
```sql
-- Create a group
CREATE ROLE readaccess;
-- Grant access to existing tables
GRANT USAGE ON SCHEMA public TO readaccess;
GRANT SELECT ON ALL TABLES IN SCHEMA public TO readaccess;
-- Grant access to future tables
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO readaccess;
-- Create a final user with password
CREATE USER <user> WITH PASSWORD '<pw>';
GRANT readaccess TO <user>;
GRANT SELECT ON ALL TABLES IN SCHEMA public TO <user>;
```
Make sure to edit /etc/postgresql/10/main/pg_hba.conf line
`local all all peer`
to
`local all all md5`
## Apache and NodeJS to serve through port :80
Edit your site on `etc/apache2/sites-enabled`.
Either at the end of your site config or at the end the VirtualHost directive of add the following:
```
<VirtualHost *:80>
...
ProxyRequests on
ProxyPass /[path]/ http://localhost:[port]/[path]/
</VirtualHost>
```
Enable the following apache modules:
```
sudo a2enmod proxy
sudo a2enmod proxy_http
sudo a2enmod proxy_balancer
sudo a2enmod lbmethod_byrequests
```
And restart Apache:
```
sudo service apache2 restart
```
Now you can serve your app through port 80 instead of 8090 or something else.
NodeJS requests will be routed to port 8090 :)
## Installation
If you don't have git, you can donwload [a zip file](https://github.com/anneb/pgserver/archive/master.zip) of the project instead.
