Erin

Self-hostable TikTok feed for your clips
Make a TikTok feed with your own videos

Introduction

Erin is a simple and self-hostable service that enables you to view your own clips using TikTok's well-known vertical swipe feed. A request was made on Reddit for a self-hostable app that can show filtered videos using TikTok's interface, so I made it. (See screenshots)

Features

Erin has all these features implemented :

Display your own videos using TikTok's swipe feed
Mask the videos you don't want to see in your feed
Simple lazy-loading mechanism for your videos
Automatic clip-naming based on file name
Simple and optional security using a master password
Support for HTTP and HTTPS
Support for Docker / proxy deployment

On top of these, please note that Erin is only a React app powered entirely by Caddy. Caddy takes care of authentication, serving static files, and serving the React app all at once.

For more information, read about Configuration.

Deployment and Examples

Before proceeding, regardless of Docker, Docker Compose, or a standalone deployment, please make sure that you have created a videos directory containing all your video files. Later on, this directory will be made available to your instance of Erin (by binding a volume to your Docker container, or putting the directory next to your Caddyfile).

Deploy with Docker

You can run Erin with Docker on the command line very quickly.

You can use the following commands :

# Create a .env file
touch .env

# Edit .env file ...

# Option 1 : Run Erin attached to the terminal (useful for debugging)
docker run --env-file .env -p <YOUR-PORT-MAPPING> -v ./videos:/srv/videos:ro mosswill/erin

# Option 2 : Run Erin as a daemon
docker run -d --env-file .env -p <YOUR-PORT-MAPPING> -v ./videos:/srv/videos:ro mosswill/erin

Note : A sample.env file is located at the root of the repository to help you get started

Note : When using docker run --env-file, make sure to remove the quotes around AUTH_ENABLED and AUTH_SECRET, or else your container might crash due to unexpected interpolation and type conversions operated by Docker behind the scenes.

Deploy with Docker Compose

To help you get started quickly, a few example docker-compose files are located in the "examples/" directory.

Here's a description of every example :

docker-compose.simple.yml: Run Erin as a front-facing service on port 443, with environment variables supplied in the docker-compose file directly.
docker-compose.proxy.yml: A setup with Erin running on port 80, behind a proxy listening on port 443.

When your docker-compose file is on point, you can use the following commands :

# Run Erin in the current terminal (useful for debugging)
docker-compose up

# Run Erin in a detached terminal (most common)
docker-compose up -d

# Show the logs written by Erin (useful for debugging)
docker logs <NAME-OF-YOUR-CONTAINER>

Configuration

To run Erin, you will need to set the following environment variables in a .env file :

Note : Regular environment variables provided on the commandline work too

Note : A sample.env file is located at the root of the repository to help you get started

Parameter	Type	Description	Default
`PUBLIC_URL`	`boolean`	The public URL used to remotely access your instance of Erin. (Please include HTTP / HTTPS and the port if not standard 80 or 443. Do not include a trailing slash) (Read the official Caddy documentation)	https://localhost
`AUTH_ENABLED`	`string`	Whether Basic Authentication should be enabled. (This parameter is case sensitive) (Possible values : true, false)	true
`AUTH_SECRET`	`string`	The secure hash of the password used to protect your instance of Erin.	Hash of `secure-password`
`APP_TITLE`	`string`	The custom title that you would like to display in the browser's tab. (Tip: You can use `[VIDEO_TITLE]` here if you want Erin to dynamically display the title of the current video.)	Erin - TikTok feed for your own clips

Tip : To generate a secure hash for your instance, use the following command :

docker run caddy caddy hash-password --plaintext "your-new-password"

Note : When using docker-compose.yml environment variables, if your password hash contains dollar signs: double them all, or else the app will crash. For example : $ab$cd$efxyz becomes $$ab$$cd$$efxyz. This is due to caveats with docker-compose string interpolation system.

Troubleshoot

Should you encounter any issue running Erin, please refer to the following common problems that may occur.

If none of these matches your case, feel free to open an issue.

Erin is unreachable over HTTP / HTTPS

Erin sits on top of a Caddy web server.

As a result :

You may be able to better troubleshoot the issue by reading your container logs.
You can check the official Caddy documentation regarding addresses.
You can check the official Caddy documentation regarding HTTPS.

Other than that, please make sure that the following requirements are met :

If Erin runs as a standalone application without proxy :
- Make sure your server / firewall accepts incoming connections on Erin's port.
- Make sure your DNS configuration is correct. (Usually, such record should suffice : A erin XXX.XXX.XXX.XXX for https://erin.your-server-tld)
- Make sure your .env file is well configured according to the Configuration section.
If Erin runs inside Docker / behind a proxy :
- Perform the previous (standalone) verifications first.
- Make sure that PUBLIC_URL is well set in .env.
- Check your proxy forwarding rules.
- Check your Docker networking setup.

In any case, the crucial part is Configuration and reading the official Caddy documentation.

Erin says that no video was found on my server

For Erin to serve your video files, those must respect the following requirements :

The file extension is one of .mp4, .ogg, .webm. (There are the only extensions supported by web browsers.)
The files are located in /srv/videos on your Docker container using a volume.

To make sure that your videos are inside your Docker container and in the right place, you can :

Run docker exec -it <NAME-OF-YOUR-CONTAINER> sh
Inside the newly-opened shell, run : ls /srv/videos
You should see your video files here. If not, then check your volume-binding.

If Erin is still unable to find your videos despite everything being well-configured, please open an issue including the output of your browser's Javascript console and network tab when the request goes to /media/. It may have to do with browser-caching, invalid configuration, or invalid credentials.

How can I add new videos to my feed?

For now, you should just put your new video files into your videos directory that is mounted with Docker. Erin will automatically pick up these new files, and when you refresh your browser you'll see them.

How should I name my video files?

Erin will automatically translate your file name into a title to display on the interface.

The conversion operated is as follows :

- becomes
__ becomes -

Here's a few examples to help you name your files :

Vegas-trip__Clip-1.mp4 becomes Vegas trip - Clip 1
Spanish-language__Lesson-1.mp4 becomes Spanish language - Lesson 1
Spiderman-1.ogg becomes Spiderman 1

In what order will my files appear in the feed?

Erin randomly shuffles your video files on every browser refresh.

As a result, there is no specific order for your videos to appear.

Some of my videos seem to be missing or not loaded at all

For now, Erin will only attempt to retrieve the videos that have a supported extension.

Supported extensions are : .webm, .mp4, and .ogg.

However, please note that Safari doesn't seem to support .ogg, hence these videos will be ignored for Safari users.

Should you have any advice or idea to support more extensions (especially for Safari users), please feel free to open an issue.

My custom password doesn't work

There seems to be a few caveats when using Docker / Docker Compose with Caddy-generated password hashes.

These are the rules you should follow :

If you deployed Erin using the Docker CLI, via the command docker run ... --env-file .env ..., then your AUTH_SECRET should have no quote at all, and all the dollar signs should stay as they are without escape or doubling
If you deployed Erin using Docker Compose, via a docker-compose.yml file, then your AUTH_SECRET should have its dollar signs doubled. Example : i$am$groot becomes i$$am$$groot.

That said, remember that your password hash must be generated with the following command :

docker run caddy caddy hash-password --plaintext "your-new-password"

Something else

Please feel free to open an issue, explaining what happens, and describing your environment.
