Install
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
ADMIN_PASSWD=something...
for any non-development deployments - pull prepared images from the DockerHub 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 withzip
(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,arm]

-
SECRET
- secret key, can be any long and hard-to-guess string. -
REMARK_URL
- url pointing to your remark42 server, i.e.https://demo.remark42.com
- At least one pair of
AUTH_<PROVIDER>_CID
andAUTH_<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
Quick installation test
To verify if remark has been properly installed, check a demo page at ${REMARK_URL}/web
URL. Make sure to include remark
site id to ${SITE}
list.
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
. iehttps://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.
Microsoft Auth Provider
- Register a new application using the Azure portal .
- Under "Authentication/Platform configurations/Web" enter the correct url constructed as domain +
/auth/microsoft/callback
. i.e.https://example.mysite.com/auth/microsoft/callback
- In "Overview" take note of the Application (client) ID
- Choose the new project from the top right project dropdown (only if another project is selected)
- Select "Certificates & secrets" and click on "+ New Client Secret".
Twitter Auth Provider
- Create a new twitter application https://developer.twitter.com/en/apps
- Fill App name , Description and URL of your site
- In the field Callback URLs enter the correct url of your callback handler e.g. domain +
/auth/twitter/callback
- Under Key and tokens take note of the Consumer API Key and Consumer API Secret key . Those will be used as
AUTH_TWITTER_CID
andAUTH_TWITTER_CSEC
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
. iehttps://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.
Anonymous Auth Provider
Optionally, anonymous access can be turned on. In this case an extra anonymous
provider will allow logins without any social login with any name satisfying 2 conditions:
- name should be at least 3 characters long
- name has to start from the letter and contains letters, numbers, underscores and spaces only.
Importing comments
Remark supports importing comments from Disqus, WordPress or native backup format. All imported comments has Imported
field set to true
.
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_SHARED_ID=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.
Docker parameters
Two parameters allow customizing Docker container on the system level:
APP_UID TIME_ZONE
see umputun/baseimage for more details
example of docker-compose.yml
:
version: '2' services: remark42: image: umputun/remark42:latest restart: always container_name: "remark42" environment: - APP_UID=2000 # runs remark42 app with non-default UID - TIME_ZONE=GTC # sets container time to UTC - 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
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 = { host: "REMARK_URL", // hostname of remark server, same as REMARK_URL in backend config, e.g. "https://demo.remark42.com" site_id: 'YOUR_SITE_ID', components: ['embed'], // optional param; which components to load. default to ["embed"] // to load all components define components as ['embed', 'last-comments', 'counter'] // available component are: // - 'embed': basic comments widget // - 'last-comments': last comments widget, see `Last Comments` section below // - 'counter': counter widget, see `Counter` section below url: 'PAGE_URL', // optional param; if it isn't defined // `window.location.origin + window.location.pathname` will be used, // // Note that if you use query parameters as significant part of url // (the one that actually changes content on page) // you will have to configure url manually to keep query params, as // `window.location.origin + window.location.pathname` doesn't contain query params and // hash. For example default url for `https://example/com/example-post?id=1#hash` // would be `https://example/com/example-post`. // // The problem with query params is that they often contain useless params added by // various trackers (utm params) and doesn't have defined order, so Remark treats differently // all this examples: // https://example.com/?postid=1&date=2007-02-11 // https://example.com/?date=2007-02-11&postid=1 // https://example.com/?date=2007-02-11&postid=1&utm_source=google // // If you deal with query parameters make sure you pass only significant part of it // in well defined order 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 locale: 'en' // set up locale and language, if it isn't defined default value ('en') will be used }; (function(c) { for(var i = 0; i < c.length; i++){ var d = document, s = d.createElement('script'); s.src = remark_config.host + '/web/' +c[i] +'.js'; s.defer = true; (d.head || d.body).appendChild(s); } })(remark_config.components || ['embed']); </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');
Locales
Right now Remark is translated to en, ru (partially), de, and fi languages. You can pick one using.
Do you want translate remark42 to other locale? Please see this documentation for details.
Last comments
It's a widget which renders list of last comments from your site.
Add this snippet to the bottom of web page, or adjust already present remark_config
to have last-comments
in components
list:
<script> var remark_config = { host: "REMARK_URL", // hostname of remark server, same as REMARK_URL in backend config, e.g. "https://demo.remark42.com" site_id: 'YOUR_SITE_ID', components: ['last-comments'] }; (function(c) { for(var i = 0; i < c.length; i++){ var d = document, s = d.createElement('script'); s.src = remark_config.host + '/web/' +c[i] +'.js'; s.defer = true; (d.head || d.body).appendChild(s); } })(remark_config.components || ['embed']); </script>
And then add this node in the place where you want to see last comments widget:
<div 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, or adjust already present remark_config
to have counter
in components
list:
<script> var remark_config = { host: "REMARK_URL", // hostname of remark server, same as REMARK_URL in backend config, e.g. "https://demo.remark42.com" site_id: 'YOUR_SITE_ID', components: ['counter'] }; (function(c) { for(var i = 0; i < c.length; i++){ var d = document, s = d.createElement('script'); s.src = remark_config.host + '/web/' +c[i] +'.js'; s.defer = true; (d.head || d.body).appendChild(s); } })(remark_config.components || ['embed']); </script>
And then add a node like this in the place where you want to see a number of comments:
<span 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 use url
property from remark_config
object, or window.location.origin + window.location.pathname
if nothing else is defined.
Build from the source
- to build Docker container -
make docker
. This command will produce containerumputun/remark42
. - to build a single binary for direct execution -
make OS=<linux|windows|darwin> ARCH=<amd64|386>
. This step will produce executableremark42
file with everything embedded.
Development
You can use fully functional local version to develop and test both frontend & backend. It requires at least 2GB RAM or swap enabled
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 ofin 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 the latest stable go
toolchain installed .
To run backend - cd backend; go run app/main.go server --dbg --secret=12345 --url=http://127.0.0.1:8080 --admin-passwd=password --site=remark
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://admin:password@127.0.0.1:8080/api/v1/find?site=remark&sort=-active&format=tree&url=http://127.0.0.1:8080
Frontend development
Developer guide
Frontend guide can be found here: ./frontend/Readme.md
Build
You should have at least 2GB RAM or swap enabled for building
- install Node.js 12.11 or higher;
- install NPM 6.13.4 ;
- run
npm install
inside./frontend
; - run
npm run build
there; - result files will be saved in
./frontend/public
.
NoteRunning npm install
will set up precommit hooks into your git repository. It used to reformat your frontend code using prettier
and lint with eslint
and stylelint
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
The best way for start local developer enviroment:
cp compose-dev-frontend.yml compose-private-frontend.yml docker-compose -f compose-private-frontend.yml up --build cd frontend npm run dev
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
andCACHE_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.
- Images can be proxied (
IMAGE_PROXY_HTTP2HTTPS=true
) to prevent mixed http/https. - All images can be proxied and saved (
IMAGE_PROXY_CACHE_EXTERNAL=true
) instead of serving from original location. Beware, images which are posted with this parameter enabled will be served from proxy even after it will be disabled. - Docker build uses publicly available base images.
很遗憾的说,推酷将在这个月底关闭。人生海海,几度秋凉,感谢那些有你的时光。
