parcel – A simple file upload tool

---

Parcel is a simple light-weight file upload application with a nice UI and a small set of features.

• Support multiple users and administrators
• Uploaded files can be made public to allow download from anywhere
• Number of downloads can be limited, and downloads can have an expiry date
• Files are stored in separate cache directory
• Data is stored in an SQLite database
• Written in Rust using the Poem web framework
• Styled using Tailwind CSS
• Using Preact and Web Components

Running Parcel

The easiest way to run Parcel is with Docker, using the blakerain/parcel image on Dockerhub:

docker run blakerain/parcel

Parcel can be controlled through arguments or environment variables. The environment variables are a useful way to control Parcel when creating a Docker container.

Environment Name	Default	Description
DB	sqlite://parcel.db	SQLite connection string
CACHE_DIR	./cache	Directory for file cache
COOKIE_SECRET		Secret used for session cookie encryption
ANALYTICS_DOMAIN		Domain to use for analytics script
PLAUSIBLE_SCRIPT		URL for Plausible Analytics script

For example, if you had created a volume parcel_data and mounted it under /data you could tell Parcel to store the DB and file cache in that location by setting the DB environment variable to sqlite:///data/parcel.db and CACHE_DIR to /data/cache.

If you do not set the COOKIE_SECRET, you will end up being logged out every time that the container starts. To mitigate this, pass a value for COOKIE_SECRET when starting the container.

docker run -d \
  --name my-parcel \
  -e DB=sqlite:///data/parcel.db \
  -e CACHE_DIR=/data/cache \
  -e COOKIE_SECRET=$(openssl rand -base64 32 | tr -d '\n' ; echo) \
  -e ANALYTICS_DOMAIN=parcel.example.com \
  -e PLAUSIBLE_SCRIPT=https://pa.example.com/js/script.js \
  -v parcel_data:/data

Development

When running as a development server, cargo watch is mighty helpful. You may also wish to set up a cookie key (in the COOKIE_SECRET environment variable) to avoid being signed out after a restart:

# Initial setup of a cookie key
COOKIE_SECRET=$(openssl rand -base64 32 | tr -d '\n' ; echo)
export COOKIE_SECRET

# Run the server, but recompile/restart on any changes
cargo watch -L debug -x run
