HackMD lets you create realtime collaborative markdown notes on all platforms.
Inspired by Hackpad, with more focus on speed and flexibility.
Still in the early stage, feel free to fork or contribute to HackMD.
Thanks for using! ๐
Before you go too far, here is the great docker repo for HackMD.
With docker, you can deploy a server in minutes without any downtime.
You can quickly setup a sample heroku hackmd application by clicking the button below.
We've dropped MongoDB after version 0.4.0.
So here is the migration tool for you to transfer the old DB data to the new DB.
This tool is also used for official service.
- Chrome >= 47, Chrome for Android >= 47
- Safari >= 9, iOS Safari >= 8.4
- Firefox >= 44
- IE >= 9, Edge >= 12
- Opera >= 34, Opera Mini not supported
- Android Browser >= 4.4
- Node.js 4.x or up (test up to 6.7.0)
- Database (PostgreSQL, MySQL, MariaDB, SQLite, MSSQL) use charset
utf8
- npm and bower
- Download a release and unzip or clone into a directory
- Enter the directory and type
bin/setup
, which will install npm/bower dependencies and create configs. The setup script is written in Bash, you would need bash as a prerequisite. - Setup the configs, see more below
- Setup environment variables which will overwrite the configs
- Build front-end bundle by
npm run build
(usenpm run dev
if you are in development) - Run the server as you like (node, forever, pm2)
If you are upgrading HackMD from an older version, follow these steps:
- Fully stop your old server first (important)
git pull
or do whatever that updates the filesnpm install && bower install
to update dependencies- Modify the file named
.sequelizerc
, change the value of the variableurl
with your db connection string For example:postgres://username:password@localhost:5432/hackmd
- Run
node_modules/.bin/sequelize db:migrate
, this step will migrate your db to the latest schema - Start your whole new server!
