GCP	Cloud Blog	The serverless gambit: Building ChessMsgs.com on Cloud Run	https://cloud.google.com/blog/topics/developers-practitioners/serverless-gambit-building-chessmsgscom-cloud-run/	The serverless gambit Building ChessMsgs com on Cloud RunWhile watching The Queen s Gambit on Netflix just recently I was reminded about how much I used to enjoy playing chess I was eager to play a game so I started to tweet “D D knowing that someone would recognize this as an opening move and likely respond with their move giving me the fix I needed I paused before hitting the tweet button because I realized that I d need to set up a board physical or virtual to keep track of the game If I received multiple responses I d need multiple boards I decided not to send the tweet Later in the day I had the idea to create a simple service that addresses my use case Instead of designing a full chess site I decided to create a chess board logger visualizer to make it practical to play via Twitter or any other messaging social platform Instead of tweeting moves back and forth players tweet links back and forth and those links go to a site that renders the current chessboard allows a new move and creates a new link to paste back to the opponent I wanted this to be serverless meaning that it will scale to zero and have zero maintenance requirements Excited about this idea I put together a shopping list My MVP requirements Represent the board position ideally completely in the URL to keep it stateless from a server side perspectiveDisplay a chessboard and let the player make their next move Stretch goals Enforce chess rules allow only legal moves Dynamically create a png jpg of the chessboard that I can use as an Open Graph and Twitter card image so that when a player sends the link the image of the board will automatically display Putting it all togetherRepresenting the board positionThere is a standard notation for describing a particular board position of a chess game called Forsyth Edwards Notation FEN that was exactly what I needed A FEN is a sequence of ASCII characters For example the starting position for any chess game can be represented by the following string rnbqkbnr pppppppp PPPPPPPP RNBQKBNR w KQkq Each letter is a piece pawn P knight N bishop B rook R queen Q and king K Uppercase letters represent white pieces and lowercase letters represent black The last part of the string is specific to certain rules in chess read more about FEN I knew I could use this in the URL so my first requirement was complete and I was able to represent the board state in the URL eliminating the need for a backend data store Displaying the chessboard and allowing drag and drop movesNumerous chess libraries are available One in particular that caught my eye was chessboard js described as “a JavaScript chessboard component with a flexible just a board API I quickly discovered that this library can display chess boards from a FEN allow pieces to be moved and update the FEN Perfect In only two hours I had the basic functionality implemented Enforcing chess rulesI originally thought that making this service aware of chess rules would be difficult but then I saw the example in the chessboard js docs showing how to integrate it with another library called chess js “a JavaScript chess library that is used for chess move generation validation piece placement movement and check checkmate stalemate detection basically everything but the AI A short time later I had it working Stretch goal completed Where s what a couple of game moves look like Moving the pawn from D to D in a new game b KQkq d amp to d amp from d amp gid mOhlhRlMboYsHLqBFfIBlack countering with a similar move of pawn from D to D w KQkq d amp to d amp from d amp gid mOhlhRlMboYsHLqBFfIThe URL has the following data fen the new board positionfrom and to indicating what move occurred I use this to highlight the squares gid a unique game ID I used nanoid I ll use this to connect moves to a single game in the future For example I could add a feature that lets the user request the entire game transcript  Done Except At this point there were no server requirements other than simple HTML static hosting But after playing it with some friends and family I decided that I really wanted to accomplish the other stretch goal dynamically create a png jpg of the chessboard that I can use as an Open Graph and Twitter card image  With this capability an image of the board will automatically display when a player sends the link Without it the game is a series of ugly URLs Dynamically creating the Open Graph imageThis requirement introduced some server side requirements I needed two things to happen on the server First I needed to dynamically generate a board image from a FEN Once again open source to the rescue almost I found chess image generator a JavaScript library that creates a png from a FEN I wrapped this in a bit of Node js Express code so that I could access the image as if it were static For example here s a demo of the real endpoint w KQkq png This link results in this image Second I needed to dynamically inject this FEN embedded URL into the content attribute of the meta tag in the main HTML Like me you might be thinking that you could just do some DOM manipulation in JavaScript and avoid having to dynamically change HTML on the server But the Open Graph image is retrieved by a bot from whatever service you use for messaging These bots don t execute any client side JavaScript and expect all values to be static So that led to additional server side work I needed to dynamically convert this Into something like this I could have used one of many Node templating engines to do this but they all seemed like overkill for this simple substitution requirement so I just wrote a few lines of code for some string replace calls in my Node server  With this functionality added a game on Twitter and other services now looks much better Check out the codeThe source for chessmsgs com is available on GitHub at  Deciding where to host itThe hosting requirements are simple I needed support for Node js Express domain mapping and SSL There are several options on Google Cloud including Compute Engine VMs App Engine and Kubernetes Engine For this app however I wanted to go completely serverless which quickly led me to Cloud Run Cloud Run is a managed platform that enables you to run stateless containers that are invocable via web requests or Pub Sub events  Cloud Run is also basically free for this type of project because the always free tier includes vCPU seconds GiB seconds and million requests per month as of this writing see the Cloud Run pricing page for the latest details Even beyond the free tier it s very inexpensive for this type of app because you only pay while a request is being handled on your container instance and my code is simple and fast Lastly deploying this on Cloud Run brings a lot of added benefits such as continuous deployment via Cloud Build and log management and analysis via Cloud Logging both of which are super easy to set up What s next If this suddenly becomes the most popular site of the day I m actually in good shape from a scalability point of view because of my decision to use Cloud Run If I really wanted to engineer this for extreme loads I could easily deploy it to multiple regions throughout the globe and set up a load balancer and possibly a CDN I also could separate the web hosting functionality from the image generation functionality to allow each to scale as needed When I first started thinking about the image generation I naturally thought about caching the images in Google Cloud Storage This would be easy to do and storage is crazy cheap But then I did a bit of research and learned the following fun facts After two moves one move for each player there are different distinct board positions After each player moves again two moves each this number is now distinct positions After each player moves again three moves each the number is now distinct positions I could gain a bit of performance by caching the most popular openings but each game would quickly go beyond the cached images so it didn t seem worth it By the way to cache every possible board position would be about positions which is a massive number that doesn t even have a name ConclusionThis was a fun project almost therapeutic for me since my “day job doesn t allow much time for writing code If this becomes popular I m sure others will have ideas on how to improve it  This was my first hands on with Cloud Run beyond the excellent Quick Starts examples for Go Node js Python Java C C PHP Ruby Shell etc Because of my role in developer advocacy at Google I was aware of most Cloud Run capabilities and features but after using it for something real I now understand why developers love it Where to learn moreCloud Run Product PageCloud
