| # project-fortis-services | ||
|
|
||
| [](https://travis-ci.org/CatalystCode/project-fortis-services) | ||
|
|
||
| ## Overview | ||
|
|
||
| This repository contains the services tier of the Fortis architecture, below | ||
| highlighted in red in the architecture diagram for the entire system. | ||
|
|
||
|  | ||
|
|
||
| This repository implements a NodeJS GraphQL server that sits in between the | ||
| Fortis data-store (Cassandra) and the Fortis frontend (React). | ||
|
|
||
| ## Development setup | ||
|
|
||
| As per the diagram above, there are two pieces necessary to run this repository | ||
| locally: a Cassandra database and the GraphQL server. You can spin up both of | ||
| these pieces using Docker via the following command: | ||
|
|
||
| ```sh | ||
| docker-compose up | ||
| ``` | ||
|
|
||
| The container of the GraphQL server will wait for the Cassandra database to come | ||
| live, then set up the database schema, then insert seed data (if a link to a CQL | ||
| file is provided via the `FORTIS_CASSANDRA_SEED_DATA_URL` environment variable) | ||
| and then start the GraphQL server on port 8080. | ||
|
|
||
| After the server started, head over to the following URLs to play with the | ||
| service: | ||
|
|
||
| - http://localhost:8080/api/edges/graphiql | ||
| - http://localhost:8080/api/messages/graphiql | ||
| - http://localhost:8080/api/settings/graphiql | ||
| - http://localhost:8080/api/tiles/graphiql |

There was a problem hiding this comment. Excellent! At some point, I think we could move these DDL statements into database migrations running on this project (fortis-services). |

Any chance you can add a

Great comment. I'm usually the first one to advocate for Bash strict mode (
set -euo pipefail). However, some of the commands below are expected to fail (e.g. when waiting for Cassandra to come up) so I think it's cleaner to not enable strict-mode here since otherwise we'd have to sprinkle a bunch of|| trueacross the code which may confuse folks with less Bash experience.
