Installing PostgreSQL

To start using Fhirbase you have to install PostgreSQL database first. Any version above 9.6 should be fine. Please proceed to the section describing operating system you're running.

Docker (cross-platform)

If you have Docker installed, you might want to start PostgreSQL as a Docker container:
$ docker run --name fhirbase-postgres -p=5432:5432 -e POSTGRES_PASSWORD=postgres -d postgres:latest


For Windows the most simple way is to use EnterpriseDB PostgreSQL Installer. Also there is a YouTube video demonstrating the whole installation process.


Most likely that PostgreSQL will be available through your distribution's package manager. On Ubuntu or Debian, it's as easy as
$ sudo apt-get install postgresql postgresql-client
For other Linux distributions, please use search functionality of your package manager or just Google the right command.

MacOS (Homebrew)

You can install PostgreSQL with Homebrew:
$ brew install postgresql
Also you'll need to create default user with some password (we advice to use "postgres" as password for simplicity):
$ createuser -s -P postgres
Enter password for new role: postgres
Enter it again: postgres

MacOS (

As an alternative, there is a project which provides PostgreSQL as a regular MacOS application with common drag-and-drop installation. Please follow instructions at Installation Page and especially make sure you've updated you PATH variable to be able to use psql command-line tool.
When you finished installing it, open Terminal and execute following command to set password for postgres user:
$ psql -h localhost -U postgres -c '\password postgres'
Enter new password: postgres
Enter it again: postgres

Checking Postgres connection

After you finished installing Postgres, please check it's running and accepting TCP/IP connections.
You can do this with psql command-line client or with pgAdmin GUI application. For psql, use following command:
$ psql -h localhost -p 5432 -U postgres -W postgres
Password for user postgres: xxxxxxxxxx
psql (10.4, server 9.6.3)
Type "help" for help.
postgres=# _
If you got postgres=# prompt waiting for your input, your installation is fine. You can quit psql typing \q followed by Enter.
If you got an error like this instead:
psql: could not connect to server: Connection refused
Is the server running on host "localhost" ( and accepting
TCP/IP connections on port 5432?
then it looks like PostgreSQL is either not running or not accepting TCP/IP connections. Please check presence of postgres process using your operating system's Process Viewer (or Task Manager). If postgres process is running, please consider updating pg_hba.conf file as described in this wiki article.

Downloading and installing Fhirbase

Go to Fhirbase Download page and download most recent release of Fhirbase. Make sure you've picked right file, it should match your operating system and CPU architecture. Nightly-build release is being updated after every commit to master branch, so it might be unstable.
When you downloaded the Fhirbase binary, make it executable (Windows users don't need this):
$ chmod a+x /path/to/downloads/folder/fhirbase-os-arch
Then rename it from fhirbase-os-arch to just fhirbase and put in some directory listed in you $PATH environment variable. To check that it was properly installed, type following command:
$ fhirbase help
It should output Fhirbase command-line help.
Note to Windows users: Fhirbase is a terminal application and it's supposed to be run inside Command Prompt window. If you'll just double-click it, Command Prompt window will popup and disappear immediately. To be able to use Fhirbase, do following:
  • Start Menu => Run... => cmd.exe
  • type cd C:\Path\To\Fhirbase\Exe and press Enter (use real path instead of example one)
  • type fhirbase and press Enter (make sure you've renamed downloaded exe file to just fhirbase)
If you don't know what the $PATH variable is, it's ok, you can skip this step. But you'll have to type full path to the fhirbase executable every time you'll invoke Fhirbase command. So instead of typing
$ fhirbase help
you'll need to type something like this:
$ /Users/xxxx/Downloads/fhirbase help
So please remember that if your shell says it cannot find fhirbase command, most likely fhirbase binary wasn't correctly placed inside $PATH.

Creating and initializing database

Next step is to create database where we're going to store FHIR data. Again, we can use psql command-line client or some GUI client like pgAdmin. Connect to Postgres as you previously did:
$ psql -h localhost -p 5432 -U postgres -W postgres
To create database there is a CREATE DATABASE statement:
postgres=# CREATE DATABASE fhirbase;
Do not forget to put semicolon at the end of statement. Of course, you can change "fhirbase" to any database name you want.
If you got CREATE DATABASE text as a response to your command, your database was succesfully created. Type \q to quit psql.
Now we have database, but before loading any FHIR data into it we need to create schema - some tables and stored procedures. This operation is performed with fhirbase init command:
fhirbase --host localhost -p 5432 -d fhirbase -U postgres -W postgres --fhir=3.3.0 init
Let's briefly describe meaning of command-line arguments:
  • --host localhost specifies host where Postgres is running
  • -p 5432 specifies Postgres port
  • -d fhirbase specifies name of the database to connect to (don't forget to change it if you named database differently)
  • -U postgres name of Postgres user, "postgres" is fine for most cases
  • -W postgres user's password
  • --fhir=3.3.0 FHIR version you're going to use
If you got no error, database was initialized. Most common errors are connection errors (check your Postgres credentials) and SQL errors (you're trying to initialize non-empty database).

Importing FHIR data

We're ready to import data into our newly created database. We can import data from two different sources:
Let's try to use local file first. Fhirbase GitHub repository contains sample file, go ahead and download it. When this file is on your local filesystem, invoke fhirbase load command:
fhirbase --host localhost -p 5432 -d fhirbase -U postgres -W postgres --fhir=3.3.0 load -m insert /path/to/downloaded/file/bundle.ndjson.gzip
Usually it takes from 25 to 45 seconds to import this file. At the end of the input Fhirbase will output statistics about inserted data:
Done, inserted 127454 resources in 27 seconds:
ImagingStudy 135
AllergyIntolerance 272
Claim 17937
Goal 1100
Encounter 15384
Procedure 14109
Immunization 6548
CarePlan 1544
Basic 600
Organization 768
DiagnosticReport 4143
MedicationRequest 2553
Patient 600
Condition 4142
Observation 57619
There are two different load modes: insert and copy. Using copy mode in some cases can drastically decrease load time. Also you can load data from Bulk Data API endpoints, FHIR bundles and plain JSON files. To get more information on this, take a look at load command reference.

Running Web UI and invoking SQL queries

Fhirbase contains tiny web server to provide basic Web UI for querying database. You can use it instead of desktop Postgres clients for simplicity. Following command will start Fhirbase webserver on http://localhost:3000
Fhirbase Demo running locally
fhirbase --host localhost -p 5432 -d fhirbase -U postgres -W postgres web
Point your browser to http://localhost:3000 and type following query in the editor:
SELECT COUNT(*), resource#>>'{name,0,given,0}'
FROM patient
GROUP BY resource#>>'{name,0,given,0}'
As a result you'll get most popular first names for patients stored in your database.
