# Concentrate
[](https://github.com/mbta/concentrate/actions/workflows/elixir.yml)
Concentrate combines realtime transit information from multiple sources into
single output files.
## Configuration
Concentrate can either be configured via `config/config.exs` or a JSON environment variable as `CONCENTRATE_JSON`: more details are available in [configuration.md](guides/configuration.md).
## Architecture
See [architecture.md](guides/architecture.md) for the overall architecture of the system.
## Development Setup
```
# after installing asdf from https://github.com/asdf-vm/asdf..
asdf install
# get Elixir dependencies
mix deps.get
# add pre-commit hook to verify formatting/tests/types
ln -s ../../hooks/pre-commit .git/hooks/pre-commit
# make sure everything passes! (slowest to fastest)
mix format --check-formatted
mix credo
mix test
mix dialyzer
```
If you run into issues compiling `snabbkaffe`:
``` shell
rm -fr deps/quicer
mix deps.get
mix deps.compile
```
## Docker
Concentrate comes with a Dockerfile, allowing you to build an image that can
be run anywhere Docker works. It's a [multi-stage](https://docs.docker.com/engine/userguide/eng-image/multistage-build/) build, so it requires at least Docker 17.05.
```
# build
docker build -t concentrate:latest .
# run
docker run concentrate:latest
```
