I developed this small piece of software with the specific goal to solve a niche problem of mine: being able to tell which games I own across different libraries that are also available on Steam. This allows me to better manage my main library through the Steam client by setting them as owned on other platforms. It's most definitely a first world problem but when you own multiple thousands of games you'll end up buying them multiple times accidentally, believe me.
As a data source I'm using Playnite and its export to CSV feature so that I can delegate all the web scraping and auth to a reputable app.
After launching the app you need to provide three pieces of information for it to work:
- Your Playnite libraries exported in the CSV format
- Your Steam user ID
- Your Steam API key
After that you can simply click on the crosscheck button and if everything goes accordingly the app will prompt you to specify where you want to save the output.
Playnite is a free and open source app that collects all your libraries' information into a single local database. To export your library you need to navigate to Extentions->Export Library by clicking on Playnite's icon on the top bar.
In case the export option is not appearing check if the addon is installed at Addons->Installed->Generic->Library Exporter
If it is not installed look it up under Browse->Generic and install it.
There are many ways to retrieve your UID:
If you haven't set a custom URL for your profile you can simply follow the official instructions.
Otherwise you can use one of the many websites that do this for you. One of them is steamid.io. Just make sure that you copy the Steam ID 64 format, if it's called differently on other sources you need to look for a numerical string, no other characters should be present.
Game Libraries Crosschecker needs an API key to retrieve user profiles as per the Steam API documentation. If you don't have one already you can generate one for free here. The same address will then show you the key afterwards in case you want to access it again.
If you want to build it yourself:
First you need to have Node.js installed
Then after moving to the project directory with your terminal you need to launch the following commands:
npm install- Pick whichever platform you want to target:
npm run electron:package:winnpm run electron:package:macnpm run electron:package:linuxCURRENTLY LINUX BUILD IS BROKEN FOR ELECTRON-BUILDER
The packaged app will be located in <project-dir>/dist/. If you prefer you can skip packaging altogether and launch the development environment with:
npm start
Initially I started to develop this project using Go but I quickly discovered that the GUI libraries for Go are kinda terrible so I decided to pivot and rewrite it from scratch using Electron and React. Ultimately I think it was the better choice. The Go module is still available on a separate branch as a CLI tool.
