This option is needed as it's currently not possible to add an report URI by the directives array. This option also allows to get CSP reports not only on docker based setup but also on our heroku instances. Signed-off-by: Sheogorath <sheogorath@shivering-isles.com>

HackMD Community Edition
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! 😄

Installation
Getting started (Native install)
Prerequisite
- Node.js 6.x or up (test up to 7.5.0)
- Database (PostgreSQL, MySQL, MariaDB, SQLite, MSSQL) use charset
utf8 - npm (and its dependencies, especially uWebSockets, node-gyp)
- For building HackMD we recommend to use a machine with at least 2GB RAM
Instructions
- Download a release and unzip or clone into a directory
- Enter the directory and type
bin/setup, which will install npm 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 devif you are in development) - Run the server as you like (node, forever, pm2)
Heroku Deployment
You can quickly setup a sample Heroku HackMD application by clicking the button below.
If you deploy it without the button, keep in mind to use the right buildpacks. For details check app.json.
HackMD by docker container
Debian-based version:
Alpine-based version:
The easiest way to setup HackMD using docker are using the following three commands:
git clone https://github.com/hackmdio/docker-hackmd.git
cd docker-hackmd
docker-compose up
Read more about it in the docker repository…
Upgrade
Native setup
If you are upgrading HackMD from an older version, follow these steps:
- Fully stop your old server first (important)
git pullor do whatever that updates the filesnpm installto update dependencies- Build front-end bundle by
npm run build(usenpm run devif you are in development) - Modify the file named
.sequelizerc, change the value of the variableurlwith 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!
We don't use LZString to compress socket.io data and DB data after version 0.5.0. Please run the migration tool if you're upgrading from the old version.
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.

Operational Transformation
From 0.3.2, we started supporting operational transformation. It makes concurrent editing safe and will not break up other users' operations. Additionally, now can show other clients' selections. See more at http://operational-transformation.github.io/
