title: "How to Deploy Lichess's Lila With Nginx"
|
||||
layout: post
|
||||
---
|
||||
|
||||
I was getting ready to have a public test of some changes I made to [lichess.org](https://lichess.org)'s [open source chess platform](https://lichess.org/source).
|
||||
In preperation, I got my Let's Encrypt certificates and nginx configurations setup...
|
||||
and it wouldn't work.
|
||||
Here are some tips for myself and future Lichess developers.
|
||||
|
||||
## Reasoning
|
||||
|
||||
My pull request involves accessibility.
|
||||
It will extend Lichess's NVUI (Non-Visual User Interface) to be more accessible to beginner level chess players.
|
||||
At the time of writing this, Lichess's NVUI only supports searching pieces by type, rank and file.
|
||||
It does not support any kind of interactive board.
|
||||
|
||||
I wanted to play chess with a friend of mine who uses a screen reader.
|
||||
Even though Lichess does indeed have a separate rendering of the page for visually impaired users,
|
||||
I have heard from a few people that it is not the best.
|
||||
|
||||
I don't use a screen reader myself, so I thought having a public latest changes deployed server would work better for testing.
|
||||
It would certainly work better than getting some of my less computer literate friends to connect to me via VSCode/VPN and view my local repository.
|
||||
|
||||
So here is how to deploy it:
|
||||
|
||||
## Setup a development environment
|
||||
|
||||
This is described [in Lichess's documentation itself](https://github.com/ornicar/lila/wiki/Lichess-Development-Onboarding).
|
||||
I will not elaborate further as it is not necessary.
|
||||
|
||||
## Setup nginx
|
||||
|
||||
This is the part that stumps most people.
|
||||
Getting a local development server usually works alright, but once you want to reverse proxy it for security and professionalism purposes, it get more interesting.
|
||||
|
||||
### lila
|
||||
|
||||
[Lila](https://github.com/ornicar/lila/) is the name for the main chess server, we need to change a few settings. Here is my git diff for the `conf/base.conf` file:
|
||||
|
||||
<pre class="file">
|
||||
- domain = "localhost:9663"
|
||||
- socket.domains = [ "localhost:9664" ]
|
||||
+ domain = "chess.tait.tech"
|
||||
+ socket.domains = [ "ws.chess.tait.tech" ]
|
||||
asset.domain = ${net.domain}
|
||||
- asset.base_url = "http://"${net.asset.domain}
|
||||
+ asset.base_url = "https://"${net.asset.domain}
|
||||
asset.minified = false
|
||||
- base_url = "http://"${net.domain}
|
||||
+ base_url = "https://"${net.domain}
|
||||
</pre>
|
||||
|
||||
### lila-ws
|
||||
|
||||
[Lila-ws](https://github.com/ornicar/lila-ws/) is the websocket component of Lila.
|
||||
|
||||
The most common complaint amongst aspiring Lichess developers is websockets not working.
|
||||
They constantly get these '101' responses from the websocket,
|
||||
and it also seems that the websocket returns instead of staying in the 'pending' state as it should be.
|
||||
|
||||
Here is how to fix that (in diff format):
|
||||
|
||||
<pre class="file">
|
||||
-csrf.origin = "http://127.0.0.1:9000"
|
||||
+csrf.origin = "https://chess.tait.tech"
|
||||
</pre>
|
||||
|
||||
You need to tell lila-ws where the websocket requests will be coming from. This is how to do that.
|
||||
|
||||
## Conclusion
|
||||
|
||||
This is not a long article, but just some notes for future me and Lila developers.
