`TiTiler.PgSTAC` is a [titiler](https://github.com/developmentseed/titiler) extension which connect to [pgstac](https://github.com/stac-utils/pgstac) STAC database in order to create dynamic **mosaics** based on [`Search Query`](https://github.com/radiantearth/stac-api-spec/tree/master/item-search).

## Installation

To install from PyPI and run:

```bash
# Make sure to have pip up to date
$ python -m pip install -U pip

# Install `psycopg` or `psycopg["binary"]` or `psycopg["c"]`
$ python -m pip install psycopg["binary"]

$ python -m pip install titiler.pgstac
```

To install from sources and run for development:

```
$ git clone https://github.com/stac-utils/titiler-pgstac.git
$ cd titiler-pgstac
$ python -m pip install -e .
```

### `PgSTAC` version

`titiler.pgstac` depends on `pgstac >=0.3.4` (https://github.com/stac-utils/pgstac/blob/main/CHANGELOG.md#v034).

### `psycopg` requirement

`titiler.pgstac` depends on the `psycopg` library. Because there are three ways of installing this package (`psycopg` or , `psycopg["c"]`, `psycopg["binary"]`), the user must install this separately from `titiler.pgstac`.

- `psycopg`: no wheel, pure python implementation. It requires the `libpq` installed in the system.
- `psycopg["binary"]`: binary wheel distribution (shipped with libpq) of the `psycopg` package and is simpler for development. It requires development packages installed on the client machine.
- `psycopg["c"]`: a C (faster) implementation of the libpq wrapper. It requires the `libpq` installed in the system.

`psycopg[c]` or `psycopg` are generally recommended for production use.

In `titiler.pgstac` setup.py, we have added three options to let users choose which psycopg install to use:

- `pip install titiler.pgstac["psycopg"]`: pure python
- `pip install titiler.pgstac["psycopg-c"]`: use the C wrapper (requires development packages installed on the client machine)
- `pip install titiler.pgstac["psycopg-binary"]`: binary wheels

## Launch

You'll need to have `POSTGRES_USER`, `POSTGRES_PASS`, `POSTGRES_DBNAME`, `POSTGRES_HOST`, `POSTGRES_PORT` variables set in your environment pointing to your Postgres database where pgstac has been installed.

```
export POSTGRES_USER=username
export POSTGRES_PASS=password
export POSTGRES_DBNAME=postgis
export POSTGRES_HOST=database
export POSTGRES_PORT=5432
```

```
$ pip install uvicorn
$ uvicorn titiler.pgstac.main:app --reload
```

### Using Docker

```
$ git clone https://github.com/stac-utils/titiler-pgstac.git
$ cd titiler-pgstac
$ docker-compose up --build tiler
```

It runs `titiler.pgstac` using Gunicorn web server. To run Uvicorn based version:

```
$ docker-compose up --build tiler-uvicorn
```
