CSDC DAO

This repository contains a work-in-progress webapp for the CSDC DAO. It currently has two components: a server and a GUI.

Development

This projects uses Nix to manage dependencies. To install Nix, run:

curl -L https://nixos.org/nix/install | sh

Then, enter the development shell with:

nix-shell

which will download all necessary dependencies. Most common commands are accessible from the Makefile. To list the available commands, run make.

In particular:

• For faster Haskell development, there are many ghcid-* targets.

• For Elm development, there is make gui-build.

Running the server

The first time, deploy the database and ipfs service with:

make docker

First, make sure the GUI is built with:

make gui-build

Finally, run:

make serve

and the server should be available at localhost:8080.

Setting up Fly.io

Make sure to create an account with access to the free tier.

The following commands should be executed inside the Nix shell, by running nix-shell before starting.

First, to login, run:

$ flyctl auth login

Then, the Postgres database must be created:

$ flyctl postgres create

This command will show the credentials, which should be saved in a secrets.json file as:

{
  "pgstring": "postgresql://user:password@host:port"
}

Finally, create your app:

$ flyctl launch

In this step you will choose the app name, which will determine its URL. This name should be used for the tag-and-push-image

In the following, the app name will be called $APP_NAME.

Make dure the image is in the fly.toml configuration file:

[build]
  image = "registry.fly.io/$APP_NAME:latest"

Save this name in the secrets.json file:

{
  "app_name": "$APP_NAME",
  "pgstring": "postgresql://user:password@host:port"
}

Building and deploying

Once more, all commands should be run inside the Nix shell, by running nix-shell before starting.

First, build the docker image and load it:

$ just build-and-load-image

Tag the image conveniently, and push it:

$ just tag-and-push-image $APP_NAME

And finally, deploy:

$ just deploy $APP_NAME
