Build Status

Strapdown-Zeta is a git-powered wiki system for hackers, derived from strapdown.js project.

Strapdown.js makes it embarrassingly simple to create elegant Markdown documents. No server-side compilation required.

Strapdown-Zeta add more features including a standalone server providing a git powered wiki system, on top of libgit2, we don't want any potential command injections!


Strapdown Static Markdown Page

  • Search Engine friendly.
  • Cross-browser compatible and responsive in mobile screens.
  • GitHub flavored Markdown syntax.
  • MathJax support. Feel free to type in your awesome math equations.
  • Theme switchable. 15 Bootstrap themes included by default, you can add more as you wish. And everybody can switch the theme thru one click.
  • Table of Content auto generation. Just specify toc="true" in the xmp tag
  • Heading numbering and anchor support, just one click will bring you to the section you are going to.
  • Use highlight.js for syntax highlighting, which provides more beautiful coloring and more powerful syntax parsing.
  • Blazing fast loading speed! All the codes are written using vanilla-js, only less than 200KiB source code after compressing.

Git powered Wiki

  • Git Powered Wiki system. A standalone server is provided, just git init then run the server will get you a full functional geeky wiki server.
  • File modification history and view by commit version(shortened sha hash).
  • Custom view options can be specified for different files.
  • Handle of static files. Directory listing can be turned on and off.

Use Strapdown static html

Open your favorite text editor, paste the following lines into the text, then type markdown content in the middle, save the file as test.html, and open it, here you go!

<!DOCTYPE html> <html> <title>Hello, Strapdown</title> <meta charset="utf-8"> <xmp theme="cerulean" style="display:none;">

# title

your awesome markdown content goes here...

</xmp> <script src=""></script> </html>

Alternatively use src attribute

You can points to an external script file through the src attribute:

<!DOCTYPE html> <html> <title>Hello, Strapdown</title> <meta charset="utf-8">
<xmp theme="cerulean" style="display:none;" src="">
</xmp> <script src=""></script> </html>

(in this example we display parsed file located at same path).

src attribute specifies the URL of an external markdown file.

It should be placed on same domain because of web browsers same-origin policy.

Choose theme

You can set your favorite theme in xmp tag. The following themes are built-in by default.

  • Chaitin
  • Amelia
  • Bootstrap
  • Cerulean
  • Cosmo
  • Cyborg
  • Flatly
  • Journal
  • Readable
  • Simplex
  • Slate
  • Spacelab
  • Spruce
  • Superhero
  • United

To use Cosmo, use the following line

<!DOCTYPE html> <html> <title>Hello, Strapdown</title> <meta charset="utf-8"> <xmp theme="cosmo" style="display:none;">

your awesome markdown content goes here...

</xmp> <script src=""></script> </html>

Table of Content

To generate table of content, specify toc="true" in xmp tag.

<!DOCTYPE html> <html> <title>Hello, Strapdown</title> <meta charset="utf-8"> <xmp theme="cosmo" toc="true" style="display:none;">

your awesome markdown content goes here...

</xmp> <script src=""></script> </html>

Strapdown Server

The server supports the following parameters.

  • -addr="", specify the listening host:port tuple, multiple addresses can be specified by separation of comma, e.g.,
  • -init, do automatic git init before starting the server, if git repo not found in working directory.
  • -dir=/path/to/dir, use the directory as the root of the git powered wiki.
  • -title=MyTitle, specify the default title of Wiki
  • -auth=.htpasswd, specify the authentication file to use, htpasswd format
  • -heading_number=true|false, set default value for whether to show heading numbers
  • -toc=true|false, set default value for whether to show table of content

For normal users

Standalone downloadable binary can be downloaded at

For hackers

You can hack this project any way you want. Please follow the following build instructions to get started.


build strapdown.min.js and strapdown.min.css

$ npm install
$ grunt

The generated file would be build/strapdown.min.js and build/strapdown.min.css

Build strapdown server

The server can be built into a single standalone binary.

The server is written using go programming language.

First, you need to install go dependency libraries.

$ make -C server deps

After that, just run make in server directory.

$ cd server
$ make

or just do following in project root directory, both will work!

$ make -C server all


Just copy the strapdown-server binary to anywhere you want and run the server with proper parameters.

examples here:

$ mkdir -p /home/wiki
$ strapdown-server -dir /home/wiki -init -addr

Or,you can run in docker:

$ mkdir -p /home/wiki
$ docker build . -t wiki
$ docker run -d -p 8080:8080 -v /home/wiki:/wiki wiki -dir /wiki -init -addr :8080


The server relies on /etc/mime.types to correctly detect file mime types. So make sure /etc/mime.types exists.

for Mac OSX users, the file is builtin.

For Archlinux users, install mime-types

$ pacman -S mime-types

For other Linux distributions, install apache server will also help.

Systemd script

To run this server using systemd, copy the strapdown.service file into your /etc/systemd/system/ directory and systemctl start strapdown
