FAQ

The API always returns Disallowed URL according to robots.txt

This means that letterboxd.com does not allow this URL to be crawled per their robots.txt. Your URL probably contains sorting or expensive queries by letterboxd. Check the linked file to ensure your given URL does not match any of the listed paths.

Self-hosting

Using render

It might take a few minutes after deploying to render, before the instance becomes available.

Be aware that render currently has a free limit of 750h/month. That's exactly enough to run this single service for the whole month.

Using heroku

If you are planning on running this instance for a lot of movies, be sure to set the correct cache-eviction policy for the redis:

heroku redis:maxmemory <name-of-redis-instance> --policy allkeys-lfu

Using docker

Pre-built docker-image

You will get the newest image by pulling screeny05/letterboxd-list-radarr:latest. The image is available for both x86-64 and arm64.

Here is an example of how to use the image with docker-compose:

version: "3.8"
services:
    web:
        image: screeny05/letterboxd-list-radarr:latest
        ports:
            - 5000:5000
        environment:
            - REDIS_URL=redis://redis:6379
        depends_on:
            - redis
    redis:
        image: redis:6.0

For optimal configuration of redis, please check out the redis.conf file in this repository.

Building it yourself

git clone git@github.com:screeny05/letterboxd-list-radarr.git
cd letterboxd-list-radarr
npm install
docker-compose up -d

The file redis.conf can be used to configure your own settings for redis. It comes with a memory-limit of 256mb by default. You might want to increase that based on your usage.

Your local instance will be available on port 5000 http://localhost:5000
