# Neko

`neko` is a self-hosted, rss reader focused on simplicity and efficiency.

Backend is written in `Go` and there is a modern `React/Vite` SPA frontend.

*note: the cat ears are in your mind*

*note: as of Feb 2026, this project is now mostly rewritten by AI as an experiment, so if you want the old original version git checkout back to 39ed5fcfe9327ab4eb81c4863d9e6353f08f6c07 from a few years ago*

## Features

   * limited features (#1 feature)
   * keyboard shortcuts
      * **j** - next item
      * **k** - previous item
      * that's all you should ever need
   * automatically marks items read in an infinite stream of never-ending content (until you run out of content and it ends)
   * full text search
   * scrapes full text of pages on demand

# Installation

## Requirements

If you are using a binary, no dependencies!

(I don't actually provide the binaries though.)

 
## Building

### Docker

The easiest way to run Neko is using Docker and Docker Compose.

1. **Build and Start**:
   ```bash
   docker-compose up -d
   ```

2. **Access**:
   The web interface will be available at `http://localhost:8080`.

Data is persisted in a Docker volume named `neko-data` (mapping to `/app/data/neko.db` inside the container).

### Build from Source

Neko is designed for easy building. Static assets for the frontends are pre-built and checked into the repository in the `web/dist/` directory, so a standard Go build is all that's required for most users.

1. **Standard Build**:
   ```bash
   # Uses existing assets in web/dist/ and web/static/ via Go embed
   make build
   ```
   A `neko` binary will be created in the root directory.

2. **Full Rebuild (including UI)**:
   If you modify the React or Vanilla frontends, you'll need to rebuild them. This requires Node.js.
   ```bash
   # Rebuilds everything: cleans, builds UIs, and builds binary
   make all
   ```

3. **Updating UI Assets Only**:
   If you want to update the frontends without a full clean:
   ```bash
   make ui           # Rebuild React frontend
   make vanilla-ui   # Update Vanilla assets
   make build        # Build final binary
   ```

# Configuration

Everything can handled with a few command line flags. You shouldn't need to change the defaults most of the time.

You can also set options using a configuration file [`yaml`](http://yaml.org), described at the end of this README (but you probably don't need to.)

## Storage

By default `neko` will create the file `neko.db` in the current directory for storage.

You can override the location of this database file with the `--database` command line option or `-d` short option.

    $ neko --database=/var/db/neko.db --add=http://trenchant.org/rss.xml

which is equivalent to --

    $ neko -d /var/db/neko.db --add=http://trenchant.org/rss.xml

For expert users -- this is a [SQLite](https://sqlite.org/) database and can be manipulated with standard sqlite commands --

    $ sqlite3 neko.db .schema
    
-- will print out the database schema.

# Usage

## Web Interface

You can do most of what you need to do with `neko` from the web interface, which is what `neko` does by default.

    $ neko
    
`neko` web interface should now be available at `127.0.0.1:4994` -- opening a browser up to that should show you the interface.

You can specify a different port using the `--http` option.

    $ neko --http=9001

If you are hosting on a publicly available server instead of a personal computer, you can protect the interface with a password flag --

    $ neko --password=rssisveryimportant
    
## Add Feed

You can add feeds directly from the command line for convenience --

    $ neko --add=http://trenchant.org/rss.xml

## Crawl Feeds

Update feeds from the command line with --

    $ neko --update

This will fetch, download, parse, and store in the database your feeds.

## Export

Export de facto RSS feed standard OPML from the command line with --

    $ neko --export=opml

Change `opml` to `text` for a simple list of feed URLs, or `json` for JSON formatted output.

Export is also available in the web interface.

Import of OPML and other things is available via the web interface.

# All Command Line Options

View all command line options with `-h` or `--help`

    $ neko -h

Usage of neko:
  -a, --add http://example.com/rss.xml
    	add the feed at URL http://example.com/rss.xml
  -c, --config string
    	read configuration from file
  -d, --database string
    	sqlite database file
  -x, --export string
    	export feed. format required: text, json or opml
  -h, --help
    	print usage information
  -s, --http int
    	HTTP port to serve on
  -i, --imageproxy
    	rewrite and proxy all image requests for privacy (experimental)
  -m, --minutes int
    	minutes between crawling feeds
  -p, --password string
    	password to access web interface
  -u, --update
    	fetch feeds and store new items
  -v, --verbose
    	verbose output

These are POSIX style flags so --

    $ neko --minutes=120

is equivalent to

    $ neko -m 120

# Configuration File

For convenience, you can specify options in a configuration file.

    $ neko -c /etc/neko.conf

A subset of the command line options are supported in the configuration file, with the same semantics --

   * database
   * http
   * imageproxy
   * minutes
   * password

For example --

```
database: /var/db/neko.db
http: 9001
imageproxy: true
minutes: 90
password: VeryLongRandomStringBecauseSecurityIsFun

```


# TODO

   * manually initiate crawl/refresh from web interface (done)
   * auto-refresh feeds from web interface (done)
   * import (done)
   * mark all as read (done)
   * rewrite frontend in a modern js framework (done: React/Vite)
   * prettify interface (done)
   * cross-compilation of binaries for "normal" platforms
   * implement Gzip compression (done)

# History

## Early 2017

I decided I didn't like the [original version of this that was python and mongo](https://github.com/adammathes/neko_v1) so rewrote it. I wanted to learn some Go. So assume the code is not great since I don't know what I'm doing even more so than normal.

The Javascript frontend stayed still the same, I kept saying I will rewrite that too since it's old backbone.js code but it still seems to mostly work. It's not very pretty though.

## July 2018 -- v0.2

Significant changes to simplify setup, configuration, usage. The goal was typing `neko` should be all you need to do to get started and use the software.

   * removed MySQL requirement (eliminating a ton of configuration and complexity)
   * added SQLite support (easier!)
   * auto-initialization of database file with embedded schema
   * removed json-formatted config file -- all options are command line options
   * `neko` runs web server by default
   * `neko` server crawls feeds regularly rather than requiring cron

## February 2026 -- v.03 -- Vibe-code Modernization

*WELCOME TO THE GEMINI ERA*

The project underwent a significant modernization phase with the help of Google Antigravity, Gemini, and Claude:

   * **Architecture**: Refactored backend into a clean REST API.
   * **Frontend**: Completely rewrote the legacy Backbone.js frontend in React/Vite as a modern Single Page Application (SPA).
   * **Performance**: Implemented robust Gzip compression and optimized asset delivery.
   * **Stability**: Added a comprehensive test suite with high coverage across both backend and frontend.
   * **Modern Standards**: Fully adopted Go modules and modern JavaScript build tooling.
