Backend

With Docker

this is the recommended way to run remark42

copy provided docker-compose.yml and customize for your needs
make sure you don't keep DEV_PASSWD=something... for any non-development deployments
pull prepared images from the docker hub and start - docker-compose pull && docker-compose up -d
alternatively compile from the sources - docker-compose build && docker-compose up -d

Without docker

download archive for stable release or development version
unpack with gunzip (Linux, macOS) or with zip (Windows)
run as remark42.{os}-{arch} server {parameters...}, i.e. remark42.linux-amd64 server --secret=12345 --url=http://127.0.0.1:8080
alternatively compile from the sources - make OS=[linux|darwin|windows] ARCH=[amd64,386,arm64,arm32]

Required parameters

Most of the parameters have sane defaults and don't require customization. There are only a few parameters user has to define:

SECRET - secret key, can be any long and hard-to-guess string.
REMARK_URL - url pointing to your remark42 server, i.e. https://demo.reamark42.com
At least one pair of AUTH_<PROVIDER>_CID and AUTH_<PROVIDER>_CSEC defining oauth2 provider(s)

The minimal docker-compose.yml has to include all required parameters:

version: '2'

services:
    remark42:
        image: umputun/remark42:latest
        restart: always
        container_name: "remark42"
        environment:
            - REMARK_URL=https://demo.remark42.com  # url pointing to your remark42 server
            - SITE=YOUR_SITE_ID                     # site ID, same as used for `site_id`, see "Setup on your website"
            - SECRET=abcd-123456-xyz-$%^&           # secret key
            - AUTH_GITHUB_CID=12345667890           # oauth2 client ID
            - AUTH_GITHUB_CSEC=abcdefg12345678      # oauth2 client secret
        volumes:
            - ./var:/srv/var                        # persistent volume to store all remark42 data

Register oauth2 providers

Authentication handled by external providers. You should setup oauth2 for all (or some) of them to allow users to make comments. It is not mandatory to have all of them, but at least one should be correctly configured.

Google Auth Provider

Create a new project: https://console.developers.google.com/project
Choose the new project from the top right project dropdown (only if another project is selected)
In the project Dashboard center pane, choose "API Manager"
In the left Nav pane, choose "Credentials"
In the center pane, choose "OAuth consent screen" tab. Fill in "Product name shown to users" and hit save.
In the center pane, choose "Credentials" tab.
- Open the "New credentials" drop down
- Choose "OAuth client ID"
- Choose "Web application"
- Application name is freeform, choose something appropriate
- Authorized origins is your domain ex: https://remark42.mysite.com
- Authorized redirect URIs is the location of oauth2/callback constructed as domain + /auth/google/callback, ex: https://remark42.mysite.com/auth/google/callback
- Choose "Create"
Take note of the Client ID and Client Secret

instructions for google oauth2 setup borrowed from oauth2_proxy

GitHub Auth Provider

Create a new "OAuth App": https://github.com/settings/developers
Fill "Application Name" and "Homepage URL" for your site
Under "Authorization callback URL" enter the correct url constructed as domain + /auth/github/callback. ie https://remark42.mysite.com/auth/github/callback
Take note of the Client ID and Client Secret

Facebook Auth Provider

From https://developers.facebook.com select "My Apps" / "Add a new App"
Set "Display Name" and "Contact email"
Choose "Facebook Login" and then "Web"
Set "Site URL" to your domain, ex: https://remark42.mysite.com
Under "Facebook login" / "Settings" fill "Valid OAuth redirect URIs" with your callback url constructed as domain + /auth/facebook/callback
Select "App Review" and turn public flag on. This step may ask you to provide a link to your privacy policy.

Yandex Auth Provider

Create a new "OAuth App": https://oauth.yandex.com/client/new
Fill "App name" for your site
Under Platforms select "Web services" and enter "Callback URI #1" constructed as domain + /auth/yandex/callback. ie https://remark42.mysite.com/auth/yandex/callback
Select Permissions. You need following permissions only from the "Yandex.Passport API" section:
- Access to user avatar
- Access to username, first name and surname, gender
Fill out the rest of fields if needed
Take note of the ID and Password

For more details refer to Yandex OAuth and Yandex.Passport API documentation.

Initial import from Disqus

Disqus provides an export of all comments on your site in a g-zipped file. This is found in your Moderation panel at Disqus Admin > Setup > Export. The export will be sent into a queue and then emailed to the address associated with your account once it's ready. Direct link to export will be something like https://<siteud>.disqus.com/admin/discussions/export/. See importing-exporting for more details.
Move this file to your remark42 host within ./var and unzip, i.e. gunzip <disqus-export-name>.xml.gz.
Run import command - docker exec -it remark42 import -p disqus -f {disqus-export-name}.xml -s {your site id}

Initial import from WordPress

Install WordPress plugin to export comments and follow it instructions. The plugin should produce a xml-based file with site content including comments.
Move this file to your remark42 host within ./var
Run import command - docker exec -it remark42 import -p wordpress -f {wordpress-export-name}.xml -s {your site id}

Backup and restore

Automatic backups

Remark42 by default makes daily backup files under ${BACKUP_PATH} (default ./var/backup). Backups kept up to ${MAX_BACKUP_FILES} (default 10). Each backup file contains exported and gzipped content, i.e., all comments. At any point, the user can restore such backup and revert all comments to the desirable state. Note: restore procedure cleans the current data store and replaces all comments with comments from the backup file.

For safety and security reasons restore functionality not exposed outside of your server by default. The recommended way to restore from the backup is to use provided scripts/restore-backup.sh. It can run inside the container:

docker exec -it remark42 restore -f {backup-filename.gz} -s {your site id}

Manual backup

In addition to automatic backups user can make a backup manually. This command makes userbackup-{site id}-{timestamp}.gz by default.

docker exec -it remark42 backup -s {your site id}

Restore from backup

Restore will clean all comments first and then will processed with complete import from a given file.

docker exec -it remark42 restore -f {backup file name} -s {your site id}

Backup format

Backup file is a text file with all exported comments separated by EOL. Each backup record is a valid json with all key/value unmarshaled from Comment struct (see below).

Admin users

Admins/moderators should be defined in docker-compose.yml as a list of user IDs or passed in the command line.

    environment:
        - ADMIN=github_ef0f706a79cc24b17bbbb374cd234a691a034128,github_dae9983158e9e5e127ef2b87a411ef13c891e9e5

To get user id just login and click on your username or any other user you want to promote to admins. It will expand login info and show full user ID.

Setup on your website

Comments

It's a main widget which renders list of comments.

Add this snippet to the bottom of web page:

<script>
  var remark_config = {
    site_id: 'YOUR_SITE_ID',
    url: 'PAGE_URL', // optional param; if it isn't defined window.location.href will be used
    max_shown_comments: 10, // optional param; if it isn't defined default value (15) will be used
    theme: 'dark', // optional param; if it isn't defined default value ('light') will be used
    page_title: 'Moving to Remark42' // optional param; if it isn't defined `document.title` will be used
  };

  (function() {
    var d = document, s = d.createElement('script');
    s.src = '/web/embed.js'; // prepends this address with domain where remark42 is placed
    (d.head || d.body).appendChild(s);
  })();
</script>

And then add this node in the place where you want to see Remark42 widget:

<div id="remark42"></div>

After that widget will be rendered inside this node.

Themes

Right now Remark has two themes: light and dark. You can pick one using configuration object, but there is also a possibility to switch between themes in runtime. For this purpose Remark adds to window object named REMARK42, which contains function changeTheme. Just call this function and pass a name of the theme that you want to turn on:

window.REMARK42.changeTheme('light');

Last comments

It's a widget which renders list of last comments from your site.

Add this snippet to the bottom of web page:

<script>
  var remark_config = {
    site_id: 'YOUR_SITE_ID', 
  };

  (function() {
    var d = document, s = d.createElement('script');
    s.src = '/web/last-comments.js'; // prepends this address with domain where remark42 is placed
    (d.head || d.body).appendChild(s);
  })();
</script>

And then add this node in the place where you want to see last comments widget:

<div class="remark42__last-comments" data-max="50"></div>

data-max sets the max amount of comments (default: 15).

Counter

It's a widget which renders a number of comments for the specified page.

Add this snippet to the bottom of web page:

<script>
  var remark_config = {
    site_id: 'YOUR_SITE_ID',
  };

  (function() {
    var d = document, s = d.createElement('script');
    s.src = '/web/counter.js'; // prepends this address with domain where remark42 is placed
    (d.head || d.body).appendChild(s);
  })();
</script>

And then add a node like this in the place where you want to see a number of comments:

<span class="remark42__counter" data-url="https://domain.com/path/to/article/"></span>

You can use as many nodes like this as you need to. The script will found all them by the class remark__counter, and it will use data-url attribute to define the page with comments.

Also script can uses url property from remark_config object, or window.location.href if nothing else is defined.

Build from the source

to build docker container - make docker. This command will produce container umputun/remark42.
to build a single binary for direct execution - make OS=<linux|windows|darwin> ARCH=<amd64|386>. This step will produce executable remark42 file with everything embedded.

Development

You can use fully functional local version to develop and test both frontend & backend.

To bring it up run:

# if you mainly work on backend
docker-compose -f compose-dev-backend.yml build
docker-compose -f compose-dev-backend.yml up
# if you mainly work on frontend
docker-compose -f compose-dev-frontend.yml build
docker-compose -f compose-dev-frontend.yml up

It starts Remark42 on 127.0.0.1:8080 and adds local OAuth2 provider “Dev”. To access UI demo page go to 127.0.0.1:8080/web. By default, you would be logged in as dev_user which defined as admin. You can tweak any of supported parameters in corresponded yml file.

Backend docker compose config by default skips running frontend related tests. Frontend docker compose config by default skips running backend related tests and sets NODE_ENV=development for frontend build.

Backend development

In order to run backend locally (development mode, without docker) you have to have latest stable go toolchain installed.

To run backend - go run backend/app/main.go --dbg --secret=12345 --dev-passwd=password --site=remark --url=http://127.0.0.1:8080 It stars backend service with embedded bolt store on port 8080 with basic auth, allowing to authenticate and run requests directly, like this: HTTP http://dev:password@127.0.0.1:8080/api/v1/find?site=remark&sort=-active&format=tree&url=http://127.0.0.1:8080

To run backend with mongodb store mongo container should be started first - docker run -d -p 27017:27017 -name=mongo mongo:3.6 --smallfiles and then go run backend/app/main.go --dbg --secret=12345 --dev-passwd=password --site=remark --url=http://127.0.0.1:8080 --store.type=mongo --store.mongo.url=localhost

Frontend development

Build

install Node.js 8 or higher;
install NPM 6.1.0;
run npm install inside ./web;
run npm run build there;
result files will be saved in ./web/public.

Note Running npm install will set up precommit hooks into your git repository. It used to reformat your frontend code using prettier and lint with eslint before every commit.

Devserver

For local development mode with Hot Reloading use npm start instead of npm run build. In this case webpack will serve files using webpack-dev-server on localhost:9000. By visiting 127.0.0.1:9000/web you will get a page with main comments widget communicating with demo server backend running on https://demo.remark42.com. But you will not be able to login with any oauth providers due to security reasons.

You can attach to locally running backend by providing REMARK_URL environment variable.

npx cross-env REMARK_URL=http://127.0.0.1:8080 npm start

Developer build running by webpack-dev-server supports devtools for React and Redux.

Privacy

Remark42 is trying to be very sensitive to any private or semi-private information.
Authentication requesting the minimal possible scope from authentication providers. All extra information returned by them dropped immediately and not stored in any form.
Generally, remark42 keeps user id, username and avatar link only. None of these fields exposed directly - id and name hashed, avatar proxied.
There is no tracking of any sort.
Login mechanic uses JWT stored in a cookie (httpOnly, secured). The second cookie (XSRF_TOKEN) is a random id preventing CSRF.
There is no cross-site login, i.e., user's behavior can't be analyzed across independent sites running remark42.
There are no third-party analytic services involved.
User can request all information remark42 knows about and export to gz file.
Supported complete cleanup of all information related to user's activity.
Cookie lifespan can be restricted to session-only.
All potentially sensitive data stored by remark42 hashed and encrypted.

Technical details

Data stored in boltdb (embedded key/value database) files under STORE_BOLT_PATH
Each site stored in a separate boltbd file.
In order to migrate/move remark42 to another host boltbd files as well as avatars directory AVATAR_FS_PATH should be transferred. Optionally, boltdb can be used to store avatars as well.
Automatic backup process runs every 24h and exports all content in json-like format to backup-remark-YYYYMMDD.gz.
Authentication implemented with go-pkgz/auth stored in a cookie. It uses HttpOnly, secure cookies.
All heavy REST calls cached internally in LRU cache limited by CACHE_MAX_ITEMS and CACHE_MAX_SIZE with go-pkgz/rest
User's activity throttled globally (up to 1000 simultaneous requests) and limited locally (per user, usually up to 10 req/sec)
Request timeout set to 60sec
Admin authentication (--admin-password set) allows to hit remark42 API without social login and with admin privileges. Adds basic-auth for username: admin, password: ${ADMIN_PASSWD}.
User can vote for the comment multiple times but only to change the vote. Double-voting not allowed.
User can edit comments in 5 mins (configurable) window after creation.
User ID hashed and prefixed by oauth provider name to avoid collisions and potential abuse.
All avatars resized and cached locally to prevent rate limiters from oauth providers, part of go-pkgz/auth functionality.
