IBF

Important

This is the repo for IBF v2, which is not in MVP-state yet. Find the old IBF-system repo here.

A system that forecasts Early Warning alerts, disseminates notifications, and visualizes exposure information to support decision making, following the country advisory. It has:

• data pipelines producing forecasts
• back-end services ingesting and processing forecast data via API and publishing this - alongside seed data - via APIs
• to e.g. a React front-end, which is used in the NRW standalone front end in this repo, but development for it is done in a separate repo.

Read our public documentation.

Getting started

To get IBF installed locally run this script and follow any instructions it gives scripts/initial_setup/initial_setup.sh.

This guide is a text version of that script which will help you troubleshoot or fix a broken local installation, although a wipe and reinstall shouldn't take more than 5 minutes.

1. Prerequisites

• git
• Docker
• NodeJS v22+
• pnpm
• Python 3.12+
• uv
• GDAL

2. Clone and install dependencies

Because IBF needs 3 repositories you'll probably want to have them in an umbrella folder next to each other.

• backend (including pipelines): https://github.com/rodekruis/IBF
• frontend (etc): https://github.com/rodekruis/go-web-app/tree/ibf-main
• seed data: https://github.com/rodekruis/IBF-seed-data

Backend (IBF repository)

In the IBF repository

• cp services/.env.example services/.env
• npm install

Run the backend with logs to stdout: npm run start:services Run the backend without logs in stdout: npm run start:services:detach Stop the backend: npm run stop:services

The following URLs are now available

• http://localhost:4000/docs to access the api-service documentation
• http://localhost:9000/ for pg_featureserv (GIS feature service)
• http://localhost:7800/ for pg_tileserv (vector tile service)

Frontend (go-web-app directory)

In the go-web-app directory, follow the instructions from that repository on how to install dependencies and start the frontend.

Frontend (nrw-standalone, in this repository)

Alternatively, the NRW standalone front-end bundled in this repository can be built and served locally. From the IBF repository root:

• npm run setup:frontend — one-time: initialise the go-web-app submodule (sparse checkout), create its .env, and install dependencies
• npm run start:frontend — build and serve the standalone front-end on http://localhost:5173

End-to-end tests (e2e)

End-to-end tests (Playwright) live in /e2e and run against a running backend and nrw-standalone front-end. From the IBF repository root:

• npm run install:e2e — one-time: install dependencies and Playwright browsers
• npm run test:e2e — run the end-to-end tests

See the e2e README for the full setup.

Pipelines (IBF/data)

The code for the pipelines lives in the IBF repository under /data. See the readme for setup.

Seed data (ibf-seed-data)

This is under construction. There are currently some seeding scripts in data/data_management/data_upload for dev use. See the data/ folder readme for more information.

Troubleshooting

When running locally, api-service tries to connect to the wrong local port for the DB (localhost:5432)

This can happen if you run docker compose up to start the backend services, since Prisma may not get the correct env setting. Instead, always launch the services with npm run start:services:detach.
