Mweb 2 1 0. Welcome to PostgREST! Leech 2 2 3 download free. In this pre-tutorial we're going to get things running so you can create your first simple API.
PostgREST is a standalone web server which turns a PostgreSQL database into a RESTful API. It serves an API that is customized based on the structure of the underlying database.
To make an API we'll simply be building a database. All the endpoints and permissions come from database objects like tables, views, roles, and stored procedures. These tutorials will cover a number of common scenarios and how to model them in the database.
By the end of this tutorial you'll have a working database, PostgREST server, and a simple single-user todo list API.
Step 1. Relax, we'll help¶
As you begin the tutorial, pop open the project chat room in another tab. There are a nice group of people active in the project and we'll help you out if you get stuck.
Step 2. Install PostgreSQL¶
You'll need a modern copy of the database running on your system, either natively or in a Docker instance. We require PostgreSQL 9.3 or greater, but recommend at least 9.5 for row-level security features that we'll use in future tutorials.
If you're already familiar with using PostgreSQL and have it installed on your system you can use the existing installation. For this tutorial we'll describe how to use the database in Docker because database configuration is otherwise too complicated for a simple tutorial.
If Docker is not installed, you can get it here. Next, let's pull and start the database image:
This will run the Docker instance as a daemon and expose port 5432 to the host system so that it looks like an ordinary PostgreSQL server to the rest of the system.
Step 3. Install PostgREST¶
PostgREST is distributed as a single binary, with versions compiled for major distributions of Linux/BSD/Windows. Visit the latest release for a list of downloads. In the event that your platform is not among those already pre-built, see Build from Source for instructions how to build it yourself. Also let us know to add your platform in the next release.
The pre-built binaries for download are .tar.xz
compressed files (except Windows which is a zip file). To extract the binary, go into the terminal and run
The result will be a file named simply postgrest
(or postgrest.exe
on Windows). At this point try running it with
If everything is working correctly it will print out its version and information about configuration. You can continue to run this binary from where you downloaded it, or copy it to a system directory like /usr/local/bin
on Linux so that you will be able to run it from any directory.
Note
PostgREST requires libpq, the PostgreSQL C library, to be installed on your system. Without the library you'll get an error like 'error while loading shared libraries: libpq.so.5.' Here's how to fix it:
Ubuntu or DebianFedora, CentOS, or Red HatOS XWindowsIt isn't fun. Learn more here.
It might be easier to execute PostgREST in its own Docker image as well.
Step 4. Create Database for API¶
Connect to to SQL console (psql) inside the container. To do so, run this from your command line:

You should see the psql command prompt:

The first thing we'll do is create a named schema for the database objects which will be exposed in the API. We can choose any name we like, so how about 'api.' Execute this and the other SQL statements inside the psql prompt you started.
Our API will have one endpoint, /todos
, which will come from a table.
Next make a role to use for anonymous web requests. When a request comes in, PostgREST will switch into this role in the database to run queries.
The web_anon
role has permission to access things in the api
schema, and to read rows in the todos
table.
Now quit out of psql; it's time to start the API!
Step 5. Run PostgREST¶
PostgREST uses a configuration file to tell it how to connect to the database. Create a file tutorial.conf
with this inside:
The configuration file has other options, but this is all we need. Now run the server:

It's now ready to serve web requests. There are many nice graphical API exploration tools you can use, but for this tutorial we'll use curl
because it's likely to be installed on your system already. Open a new terminal (leaving the one open that PostgREST is running inside). Try doing an HTTP request for the todos.

The API replies:
With the current role permissions, anonymous requests have read-only access to the todos
table. If we try to add a new todo we are not able.

There we have it, a basic API on top of the database! In the next tutorials we will see how to extend the example with more sophisticated user access controls, and more tables and queries.
