📜 News

Codex has a NEWS file to summarize changes that affect users.

📦 Installation

Install & Run with Docker

Run the official Docker Image. Instructions for running the docker image are on the Docker Hub README. This is the recommended way to run Codex.

You'll then want to read the Administration section of this document.

Install & Run as a Native Application

You can also run Codex as a natively installed python application with pip.

Wheel Build Dependencies

You'll need to install these system dependencies before installing Codex.

macOS
brew install jpeg libffi libyaml libzip openssl python unrar webp
Linux
Debian

...and Ubuntu, Mint, MX and others.

apt install build-essential libimagequant0 libjpeg62-turbo libopenjp2-7 libssl3 libyaml-0-2 libtiff6 libwebp7 python3-dev python3-pip mupdf unrar zlib1g
Alpine
apk add bsd-compat-headers build-base jpeg-dev libffi-dev libwebp openssl-dev yaml-dev zlib-dev
Install unrar Runtime Dependency on non-debian Linux

Codex requires unrar to read CBR formatted comic archives. Unrar is often not packaged for Linux, but here are some instructions: How to install unrar in Linux

Unrar as packaged for Alpine Linux v3.14 seems to work on Alpine v3.15+

Windows

Windows users should use Docker to run Codex until this documentation section is complete.

Codex can probably run on the Windows Linux Subsystem but I haven't personally tested it yet. Try following the instructions for Debian above. There may be outstanding platform related bugs.

Contributions to the Windows documentation will be gratefully accepted on the outstanding issue or Discord.

Install Codex with pip

You may now install Codex with pip

pip3 install codex

Run Codex Natively

pip should install the codex binary on your path. Run

codex

and then navigate to http://localhost:9810/

Install & Run on your preexisting HomeAssistant server

If you have a HomeAssistant server, Codex can be installed with the following steps :

👑 Administration

Navigate to the Admin Panel

  • Click the hamburger menu ☰ to open the browser settings drawer.
  • Log in as the 'admin' user. The default administrator password is also 'admin'.
  • Navigate to the Admin Panel by clicking on its link in the browser settings drawer after you have logged in.

Change the Admin password

The first thing you should do is log in as the admin user and change the admin password.

  • Navigate to the Admin Panel as described above.
  • Select the Users tab.
  • Change the admin user's password using the small lock button.
  • You may also change the admin user's name with the edit button.
  • You may create other users and grant them admin privileges by making them staff.

Add Comic Libraries

The second thing you will want to do is log in as an Administrator and add one or more comic libraries.

  • Navigate to the Admin Panel as described above.
  • Select the Libraries tab in the Admin Panel
  • Add a Library with the "+ LIBRARY" button in the upper left.

Reset the admin password

If you forget all your superuser passwords, you may restore the original default admin account by running codex with the CODEX_RESET_ADMIN environment variable set.

CODEX_RESET_ADMIN=1 codex

or, if using Docker:

docker run -e CODEX_RESET_ADMIN=1 -v host-parent-dir/config:/config ajslater/codex

Private Libraries

In the Admin Panel you may configure private libraries that are only accessible to specific groups.

A library with no groups is accessible to every user including anonymous users.

A library with any groups is accessible only to users who are in those groups.

Use the Groups admin panel to create groups and the Users admin panel to add and remove users to groups.

Include and Exclude Groups

Codex can make groups for libraries that exclude groups of users or exclude everyone and include only certain groups of users.

PDFs

Codex only reads PDF metadata from the filename. If you decide to include PDFs in your comic library, I recommend taking time to rename your files so Codex can find some metadata. Codex recognizes several file naming schemes. This one has good results:

{series} v{volume} #{issue} {title} ({year}) {ignored}.pdf

🎛️ Configuration

Config Dir

The default config directory is config/ directly under the working directory you run codex from. You may specify an alternate config directory with the environment variable CODEX_CONFIG_DIR.

The config directory contains a file named hypercorn.toml where you can specify ports and bind addresses. If no hypercorn.toml is present Codex copies a default one to that directory on startup.

The default values for the config options are:

bind = ["0.0.0.0:9810"]
quick_bind = ["0.0.0.0:9810"]
root_path = "/codex"

The config directory also holds the main sqlite database, the Whoosh search index, a Django cache and comic book cover thumbnails.

Environment Variables

Codex

  • LOGLEVEL will change how verbose codex's logging is. Valid values are ERROR, WARNING, INFO, DEBUG. The default is INFO.
  • TIMEZONE or TZ will explicitly set the timezone in long format (e.g. "America/Los Angeles"). This is useful inside Docker because codex cannot automatically detect the host machine's timezone.
  • CODEX_CONFIG_DIR will set the path to codex config directory. Defaults to $CWD/config
  • CODEX_RESET_ADMIN=1 will reset the admin user and its password to defaults when codex starts.
  • CODEX_SKIP_INTEGRITY_CHECK=1 will skip the database integrity repair that runs when codex starts.
  • CODEX_LOG_DIR sets a custom directory for saving logfiles. Defaults to $CODEX_CONFIG_DIR/logs
  • CODEX_LOG_TO_FILE=0 will not log to files.
  • CODEX_LOG_TO_CONSOLE=0 will not log to the console.

Comicbox

  • DEBUG_TRANSFORM will show verbose information about how the comicbox library reads all archive metadata sources and transforms it into a the comicbox schema.

Reverse Proxy

nginx is often used as a TLS terminator and subpath proxy.

Here's an example nginx config with a subpath named '/codex'.

# HTTP
proxy_set_header   Host $http_host;
proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header   X-Forwarded-Host $server_name;
proxy_set_header   X-Forwarded-Port $server_port;
proxy_set_header   X-Forwarded-Proto $scheme;
proxy_set_header   X-Real-IP $remote_addr;
proxy_set_header   X-Scheme $scheme;
# Websockets
proxy_http_version 1.1;
proxy_set_header   Upgrade $http_upgrade;

proxy_set_header Connection "Upgrade" location /codex {
  proxy_pass       http://codex:9810;
  # Codex reads http basic authentication.
  # If the nginx credentials are different than codex credentials use this line to
  #   not forward the authorization.
  proxy_set_header Authorization "";
}

Specify a reverse proxy sub path (if you have one) in config/hypercorn.toml

root_path = "/codex"

Nginx Reverse Proxy 502 when container refreshes

Nginx requires a special trick to refresh dns when linked Docker containers recreate. See this nginx with dynamix upstreams article.

Restricted Memory Environments

Codex can run with as little as 1GB available RAM. Large batch jobs –like importing and indexing tens of thousands of comics at once– will run faster the more memory is available to Codex. The biggest gains in speed happen when you increase memory up to about 6GB. Codex batch jobs do get faster the more memory it has above 6GB, but with diminishing returns.

If you must run Codex in an admin restricted memory environment you might want to temporarily give Codex a lot of memory to run a very large import job and then restrict it for normal operation.

📖 Usage

👤 Sessions & Accounts

Once your administrator has added some comic libraries, you may browse and read comics. Codex will remember your preferences, bookmarks and progress in the browser session. Codex destroys anonymous sessions and bookmarks after 60 days. To preserve these settings across browsers and after sessions expire, you may register an account with a username and password. You will have to contact your administrator to reset your password if you forget it.

🗝️ API with Key Access

Codex has a limited number of API endpoints available with API Key Access. The API Key is available on the admin/stats tab.

ᯤ OPDS

Codex supports OPDS syndication and OPDS streaming. You may find the OPDS url in the side drawer. It should take the form:

http(s)://host.tld(:9810)(/root_path)/opds/v1.2/

or

http(s)://host.tld(:9810)(/root_path)/opds/v2.0/

OPDS 2.0 support is experimental and not widely or well supported by clients. OPDS 2.0 book readers exist, but I am not yet aware of an OPDS 2.0 comic reader.

Clients

HTTP Basic Authentication

If you wish to access OPDS as your Codex User. You will have to add your username and password to the URL. Some OPDS clients do not asssist you with authentication. In that case the OPDS url will look like:

http(s)://username:password@host.tld(:9810)(/root_path)/opds/v1.2/

Supported OPDS Specifications

🩺 Troubleshooting

📒 Logs

Codex collects its logs in the config/logs directory. Take a look to see what th e server is doing.

You can change how much codex logs by setting the LOGLEVEL environment variable. By default this level is INFO. To see more verbose messages, run codex like:

LOGLEVEL=DEBUG codex

Watching Filesystem Events with Docker

Codex tries to watch for filesystem events to instantly update your comic libraries when they change on disk. But these native filesystem events are not translated between macOS & Windows Docker hosts and the Docker Linux container. If you find that your installation is not updating to filesystem changes instantly, you might try enabling polling for the affected libraries and decreasing the poll_every value in the Admin console to a frequency that suits you.

Emergency Database Repair

If the database becomes corrupt, Codex includes a facitlity to rebuild the database. Place a file named rebuild_db in your Codex config directory like so:

touch config/rebuild_db

Shut down and restart Codex.

The next time Codex starts it will back up the existing database and try to rebuild it. The database lives in the config directory as the file config/db.sqlite3. If this procedure goes kablooey, you may recover the original database at config/db.sqlite3.backup.

📚Alternatives

  • Kavita has light metadata filtering/editing, supports comics, eBooks, and features for manga.
  • Komga has light metadata editing.
  • Ubooquity reads both comics and eBooks.
  • Mylar is the best comic book manager which also has a built in reader.
  • Comictagger is a comic metadata editor. It comes with a powerful command line and desktop GUI.

🤝 Contributing

🐛 Bug Reports

Issues and feature requests are best filed on the Github issue tracker.

🚫 Out of Scope

  • I have no intention of making this an eBook reader.
  • I think metadata editing would be better placed in a comic manager than a reader.

🛠 Develop

Codex is a Django Python webserver with a VueJS front end.

/codex/codex/ is the main django app which provides the webserver and database.

/codex/frontend/ is where the vuejs frontend lives.

Most of Codex development is now controlled through the Makefile. Type make for a list of commands.

💬 Support

By the generosity of the good people of Mylar, I and other Codex users answer questions on the Mylar Discord. Please use the #codex-support channel to ask for help with Codex.
