EggContractor

EggContractor

EggContractor is a self-hosted contract monitoring web app + CLI client for Egg, Inc.. It allows you to easily monitor all your contract progress, as well as peeking into prospective coops you may want to join.

Note that reverse engineered API protobufs are independently available at misc/protobuf, so you may also find this repo useful for building your own client. (There is also an initially hand-reversed version actually used by this codebase.) You can also find a best-effort contract database at misc/ContractAggregator.

Demo

Below are some semi-interactive demo pages (pre-rendered, with in-page interactivity, but inter-page interactivity is likely broken). Note that the demo pages were captured from the MVP version of EggContractor, hence somewhat outdated; since then a number of major features have been implemented; for instance, contract progress bars, offline timer for each coop member, and projection of eggs laid based on that.

• Home page: /
• Home page with time travel (state at a certain timestamp in the past): /?by=1608802500
• Peeking a coop: /peek/space-bots-2020/XXXXXXXXX/
• List of recently peeked coops: /peeked/

You can also find screenshots in the gallery.

Comparison to egginc.mioi.io

Advantages:

• No rate limiting, obviously.

• All the info about all your active contracts (solos & coops) is right on the home page. Even the coop "peeker" widget is right there. No clicking around.

• Track multiple accounts at once.

• Sort coop members by EB, egg laying rate, etc. Very handy.

• View a list of coops you recently "peeked". Demo page.

• Stats are routinely retrieved in the background (frequency easily configurable) and stored in a database. So you can project the actual number of eggs laid by taking into account how long each coop member has been offline (implemented), travel back in time to view your contract statuses in the past (implemented), or plot every player's progress.

• Send you push notifications (via Pushover) when new contracts come online.

Disadvantages:

• Frontend fanciness in general. I didn't bother to invest time into the frontend, so no pretty little pictures, no progress bars, and no dark theme (kind of a shame, not hard to add though). Hopefully you can still easily pick out whatever info you need from my UI. EggContractor now has fancy progress bars too!

• No home farm info. I don't need a separate web app to learn about my home farm, so not much of a disadvantage actually.

• No "Contract Calculator". I never used that feature so not sure how useful.

Installation & deployment

docker-compose is the recommended method of deployment. Sorry k8s fans. Currently supported platforms out-of-box: linux/386, linux/amd64,linux/arm/v6, linux/arm/v7, linux/arm64.

Nginx reverse proxying

In case you need help putting nginx in front for SSL termination and stuff, here's my nginx config:

server {
    server_name egg.my.domain;
    root /var/www/html;

    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    ssl_certificate /etc/letsencrypt/live/my.domain/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/my.domain/privkey.pem;
    include /etc/letsencrypt/options-ssl-nginx.conf;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;

    access_log /var/log/nginx/egg.access.log;
    error_log /var/log/nginx/egg.error.log;

    add_header Strict-Transport-Security "max-age=31536000" always;

    location / {
        proxy_pass         http://127.0.0.1:8080;

        proxy_http_version 1.1;
        proxy_buffering    off;
        proxy_set_header   Host                 $host;
        proxy_set_header   Origin               http://$host;
        proxy_set_header   X-Real-IP            $remote_addr;
        proxy_set_header   X-Forwarded-For      $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto    $scheme;
    }
}

server {

docker exec EggContractor /EggContractor [command]

or

docker-compose exec app /EggContractor [command]

to use the CLI. You may want to set up a shell alias.

Known issues

• When running the Docker image via Docker for Mac, with a mounted data directory, everything would seem fine and dandy until one accesses the SQLite database from the host system (e.g. do a SELECT on it), at which point all subsequent attempts to open the database from within the container would fail with "unable to open database file" (the error comes from sqlite itself, so doesn't matter if one uses the sqlite3 CLI or the golang driver; the go-sqlite3 driver does however misleadingly add a file/directory does not exist error message, which is irrelevant since the file can be open(2)'ed alright).

  This might be an issue in SQLite / Docker for Mac filesystem driver interactions. I've yet to isolate it.

  Workaround: run the Docker image on a Linux host. Probably already doing that outside of development anyway.
