[![POEditor][poeditor-image]][poeditor-url]
CodiMD lets you create real-time collaborative markdown notes on all platforms.
Inspired by Hackpad, with more focus on speed and flexibility, and build from [HackMD](https://hackmd.io) source code.
Feel free to contribute.
It is inspired by Hackpad, Etherpad and similar collaborative editors. This
project originated with the team at [HackMD](https://hackmd.io) and now forked
into its own organisation. [A longer writeup can be read in the history doc](docs/history.md).
Thanks for using! :smile:

# HackMD CE became CodiMD
To stay up to date with your installation it's recommended to join our [Matrix channel][matrix.org-url] or subscribe to the [release feed][github-release-feed].
CodiMD was recently renamed from its former name was HackMD. CodiMD is the free software version of HackMD. It was the original Version of HackMD. The HackMD team initiated CodiMD and provided a solid code base. Due to the need of paying bills, A fork was created and called HackMD EE, which is a SaaS (Software as a Service) product available at [hackmd.io](https://hackmd.io).
We decided to change the name to break the confusion between HackMD and CodiMD, formally known as HackMD CE, as it never was an open core project.
## Installation / Upgrading
Just to more confusion: We are still friends with HackMD :heart:
You can run CodiMD in a number of ways, and we created setup instructions for
all of these:
*For the whole renaming story, see the [related issue](https://github.com/hackmdio/hackmd/issues/720)*
* [Docker](docs/setup/docker.md)
* [Kubernetes](docs/setup/kubernetes.md)
* [Cloudron](docs/setup/cloudron.md)
* [Heroku](docs/setup/heroku.md)
* [manual setup](docs/setup/manual-setup.md)
# Browsers Requirement
If you do not wish to run your own setup, you can find a commercial offering at
https://hackmd.io. This is not the same codebase as this one, but it is a very
similar project.
## Configuration
Theres two main ways to configure your CodiMD instance:
[Config file](docs/configuration-config-file.md) or
[environment variables](docs/configuration-env-vars.md). You can choose what
works best for you.
CodiMD can integrate with
* facebook, twitter, github, gitlab, mattermost, dropbox, google, ldap, saml and [oauth2](docs/guides/auth/oauth.md) **for login**
* imgur, s3, minio, azure **for image/attachment storage** (files can also be local!)
* dropbox **for export and import**
More info about that can be found in the configuration docs above.
## Browser support
To use CodiMD, your browser should match or exceed these versions:
- ![Chrome](http://browserbadge.com/chrome/47/18px) Chrome >= 47, Chrome for Android >= 47
- ![Safari](http://browserbadge.com/safari/9/18px) Safari >= 9, iOS Safari >= 8.4

# Installation
## Getting started (Native install)
### Prerequisite
- Node.js 6.x or up (test up to 7.5.0) and <10.x
- Database (PostgreSQL, MySQL, MariaDB, SQLite, MSSQL) use charset `utf8`
- npm (and its dependencies, especially [uWebSockets](https://github.com/uWebSockets/uWebSockets#nodejs-developers), [node-gyp](https://github.com/nodejs/node-gyp#installation))
- `libssl-dev` for building scrypt (see [here](https://github.com/ml1nk/node-scrypt/blob/master/README.md#installation-instructions) for further information)
- For **building** CodiMD we recommend to use a machine with at least **2GB** RAM
### Instructions
1. Download a release and unzip or clone into a directory
2. 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.
3. Setup the configs, see more below
4. Setup environment variables which will overwrite the configs
5. Build front-end bundle by `npm run build` (use `npm run dev` if you are in development)
6. Modify the file named `.sequelizerc`, change the value of the variable `url` with your db connection string
For example: `postgres://username:password@localhost:5432/codimd`
7. Run `node_modules/.bin/sequelize db:migrate`, this step will migrate your db to the latest schema
8. Run the server as you like (node, forever, pm2)
To stay up to date with your installation it's recommended to join our [Matrix channel][matrix.org-url] or subscribe to the [release feed][github-release-feed].
## Heroku Deployment
You can quickly setup a sample Heroku CodiMD application by clicking the button below.
[![Deploy on Heroku](https://www.herokucdn.com/deploy/button.svg)](https://heroku.com/deploy?template=https://github.com/codimd/server/tree/master)
If you deploy it without the button, keep in mind to use the right buildpacks. For details check `app.json`.
## Kubernetes
To install use `helm install stable/hackmd`.
For all further details, please check out the offical CodiMD [K8s helm chart](https://github.com/kubernetes/charts/tree/master/stable/hackmd).
## CodiMD by docker container
[![Try in PWD](https://cdn.rawgit.com/play-with-docker/stacks/cff22438/assets/images/button.png)](http://play-with-docker.com?stack=https://github.com/codimd/container/raw/master/docker-compose.yml&stack_name=codimd)
**Debian-based version:**
[![Docker Repository on Quay](https://quay.io/repository/codimd/server/status "Docker Repository on Quay")](https://quay.io/repository/codimd/server)
**Alpine-based version:**
[![Docker Repository on Quay](https://quay.io/repository/codimd/server/status "Docker Repository on Quay")](https://quay.io/repository/codimd/server)
The easiest way to setup CodiMD using docker are using the following three commands:
```console
git clone https://github.com/codimd/container.git
cd codimd-container
docker-compose up
```
Read more about it in the [container repository…](https://github.com/codimd/container)
## Cloudron
Install CodiMD on [Cloudron](https://cloudron.io):
[![Install](https://cloudron.io/img/button.svg)](https://cloudron.io/button.html?app=io.hackmd.cloudronapp)
# Upgrade
## Native setup
:warning: When you are still running from the old repository, please run: `git remote set-url origin https://github.com/codimd/server.git` :warning:
If you are upgrading CodiMD from an older version, follow these steps:
1. Fully stop your old server first (important)
2. `git pull` or do whatever that updates the files
3. `npm install` to update dependencies
4. Build front-end bundle by `npm run build` (use `npm run dev` if you are in development)
5. Modify the file named `.sequelizerc`, change the value of the variable `url` with your db connection string
For example: `postgres://username:password@localhost:5432/codimd`
6. Run `node_modules/.bin/sequelize db:migrate`, this step will migrate your db to the latest schema
7. Start your whole new server!
To stay up to date with your installation it's recommended to join our [Matrix channel][matrix.org-url] or subscribe to the [release feed][github-release-feed].
* **migrate-to-1.1.0**
We deprecated the older lower case config style and moved on to camel case style. Please have a look at the current `config.json.example` and check the warnings on startup.
*Notice: This is not a breaking change right now but in the future*
* [**migration-to-0.5.0**](https://github.com/hackmdio/migration-to-0.5.0)
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.
* [**migration-to-0.4.0**](https://github.com/hackmdio/migration-to-0.4.0)
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.

# Configuration Using Config file
You can choose to configure CodiMD with either a config file or with
[environment variables](configuration-env-vars.md). The config file is processed
in [`lib/config/index.js`](lib/config/index.js) - so this is the first
place to look if anything is missing not obvious from this document.
Environment variables take precedence over configurations from the config files.
To get started, it is a good idea to take the `config.json.example` and copy it
to `config.json` before filling in your own details.

# Configuration Using Environment variables
You can choose to configure CodiMD with either a
[config file](configuration-config-file.md) or with environment variables.
Environment variables are processed in
[`lib/config/environment.js`](lib/config/environment.js) - so this is the first
place to look if anything is missing not obvious from this document.
Environment variables take precedence over configurations from the config files.
They generally start with `CMD_` for our own options, but we also list
node-specific options you can configure this way.

# Migrations and Notable Changes
## Migrating to 1.3.2
This is not a breaking change, but to stay up to date with the community
repository, you may need to update a few urls. This is not a breaking change.
See more at [issue #10](https://github.com/codimd/server/issues/10)
**Native setup using git:**
Change the upstream remote using `git remote set-url origin https://github.com/codimd/server.git`.
**Docker:**
When you use our [container repository](https://github.com/codimd/container)
(which was previously `codimd-container`) all you can simply run `git pull` and
your `docker-compose.yml` will be updated.
When you setup things yourself, make sure you use the new image:
[`quay.io/codimd/server`](https://quay.io/repository/codimd/server?tab=tags).
**Heroku:**
All you need to do is [disconnect GitHub](https://devcenter.heroku.com/articles/github-integration#disconnecting-from-github)
and [reconnect it](https://devcenter.heroku.com/articles/github-integration#enabling-github-integration)
with this new repository.
Or you can use our Heroku button and redeploy your instance and link the old
database again.
## Migrating to 1.1.0
We deprecated the older lower case config style and moved on to camel case style. Please have a look at the current `config.json.example` and check the warnings on startup.
*Notice: This is not a breaking change right now but will be in the future*
## Migrating to 0.5.0
[**migration-to-0.5.0**](https://github.com/hackmdio/migration-to-0.5.0)
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.
## Migrating to 0.4.0
[**migration-to-0.4.0**](https://github.com/hackmdio/migration-to-0.4.0)
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 in 0.3.2
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/](http://operational-transformation.github.io/)

# History of CodiMD
## It started with HackMD
HackMD is the origin of this project, which was mostly developed by Max Wu and
Yukai Huang. Originally, this was open source under MIT license, but was
[relicensed in October 2017 to be AGPLv3](https://github.com/hackmdio/codimd/pull/578).
At the same time, [hackmd.io](https://hackmd.io) was founded to offer a
commercial version of HackMD.
The AGPLv3-version was developed and released by the community, this was for a
while referred to as "HackMD community edition".
*For more on the splitting of the projects, please refer to [A note to our community (2017-10-11)](https://hackmd.io/c/community-news/https%3A%2F%2Fhackmd.io%2Fs%2Fr1_4j9_hZ).*
## HackMD CE became CodiMD
In June 2018, CodiMD was renamed from its former name "HackMD" and continued to
be developed under AGPLv3 by the community. We decided to change the name to
break the confusion between HackMD (enterprise offering) and CodiMD (community
project), as people mistook it for an open core development model.
*For the whole renaming story, see the [issue where the renaming was discussed](https://github.com/hackmdio/hackmd/issues/720).*
## CodiMD went independent
In March 2019, a discussion over licensing, governance and the future of CodiMD
lead to the formation of a distinct GitHub organization. Up to that point, the
community project resided in the organization of hackmdio but was for the most
part self-organized.
During that debate, we did not reach an agreement that would have allowed us to
move the repository, so we simply forked it. We still welcome the HackMD team
as part of our community, especially since a large portion of this code base
originated with them.
*For the debate that lead to this step, please refer to the [governance debate](https://github.com/hackmdio/hackmd/issues/1170) and [the announcement of the new repository](https://github.com/codimd/server/issues/10).*

# Manual Installation
## Requirements on your server
- Node.js 6.x or up (test up to 7.5.0) and <10.x
- Database (PostgreSQL, MySQL, MariaDB, SQLite, MSSQL) use charset `utf8`
- npm (and its dependencies, [node-gyp](https://github.com/nodejs/node-gyp#installation))
- `libssl-dev` for building scrypt (see [here](https://github.com/ml1nk/node-scrypt/blob/master/README.md#installation-instructions) for further information)
- For **building** CodiMD we recommend to use a machine with at least **2GB** RAM
## Instructions
1. Download a release and unzip or clone into a directory
2. 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.
3. Setup the configs, see more below
4. Setup environment variables which will overwrite the configs
5. Build front-end bundle by `npm run build` (use `npm run dev` if you are in development)
