Single user hybrid IRC client using JavaScript frontend and Node.js/Express backend.
Documentation: https://cotarr.github.io/irc-hybrid-client
Screen capture images are available in the documentation
The frontend browser code was completely rewritten and merged into the master branch as Version V2.0.0 on Sept 12, 2023. For a detail description of the changes see the CHANGELOG.md file.
The new version is intended be fully backward compatible.
Performing a git pull on irc-hybrid-client master branch will update both
frontend and backend NodeJs files.
There are no changes to the configuration files on the backend server, so previous configuration should work as-is. There are no changes to the format of the "servers.json" database of IRC server definitions. However, the file location of the root directory of the web server has changed (see CHANGELOG.md). Version 2 contains a bundled and minified version in the repository.
Installations that use custom mp3 sound files will need to move the sound files to the build-prod/sounds/ folder.
The previous version v0.2.53 of the web browser frontend will no longer be maintained. It has been tagged as v1.0.0 to place a clean version boundary to the new version. The upgraded version will begin at Version v2.0.0.
If any problems are experienced with Version 2, you can revert the GitHub master branch to the last Version 0.2.53 commit from Aug 07, 2023 commit hash f87c3d4. If the Gulp bundler is used, the irc-hybrid-client-dev-tools repository must also be rolled back as described in it's README.md file.
The upgrade of the web browser frontend to Version v2 has brought the project back into a period of rapid changes to optimize the user interface. The backend core IRC client and web server did not change in the v2 upgrade and is mostly stable.
The /docs/ folder has not been upgraded and it still contains Version 0.2.53 screen capture images. New screen captures are deferred until last minute user interface adjustments have been comleted. In general, the /docs/ instructions mostly refer to the backend web server and are still applicable to the new version.
HTML, CSS, and JavaScript content is available in both the minified-bundled version and
the commented development version. HTML source files are located in the
folder source-files/. The production minified build is located
in the folder build-prod/. Selection is determined by
the NODE_ENV environment variable. A development folder build-dev
will not be committed to avoid duplication of source files.
The server files are located in the server/ folder. The server is launched
from the socket server in the bin/ folder.
The repository contains a /docs/ folder with HTML help documentation for the project. The /docs/ web pages can be enabled in the web server configuration. (The /docs/ are not updated for V2 TBD)
There are complete step by step installation instructions in the docmentation. The steps listed here in the README.md are a minimal installation guide for people very familiar with deploying Node.js/Express servers. It is recommended to follow the documentation installation instructions instead.
- Backend web server requires Node v16 or greater.
# clone the github repository
git clone https://github.com/cotarr/irc-hybrid-client.git
cd irc-hybrid-client
# Choose 1 of the following 2 options
# Option 1 Run local to try it out. (development --> log to console)
export NODE_ENV=development
npm install
# Option 2 Typical for server installation, use minified files, log output to files.
export NODE_ENV=production
npm ciThere are two possible methods that may be used to define the web server configuration settings. The settings may be stored as properties in the "credentials.json" file, or the settings may be defined as environment variables or entries in the .env file. Only one method can be used at a time. If the credentials.json file exists, it will be parsed for settings, otherwise the environment variables will be parsed for settings.
In the case where someone may want to try the irc-hybrid-client in a virtual machine on a private network, it is possible to setup a minimal configuration. This should only be used for testing.
Most of the configuration settings can be allowed to fall back to the configuration defaults. At minimum, the configuration needs these items:
- A defined user login account
- The web server port number
- A cookie secret.
- If using TLS, the full path names to the certificate files.
To create a minimal configuration that uses the credentials.json,
copy the following JSON object, then paste it into a "credentials.json" file
in the base folder of the repository.
Protect file permissions using chmod 600 credentials.json
{
"configVersion": 2,
"loginUsers": [
{
"userid": 1,
"user": "user1",
"name": "Bob Smith",
"hash": "---BCRYPT-HASH-GOES-HERE---"
}
],
"serverTlsKey": "/home/user1/tls/privkey.pem",
"serverTlsCert": "/home/user1/tls/fullchain.pem",
"tls": true,
"port": 3003,
"cookieSecret": "---COOKIE-SECRET-GOES-HERE---"
}To make a minimal configuration that uses environment variables,
copy the following environment variables, then paste them into a .env file
in the base folder of the repository.
Protect file permissions using chmod 600 .env.
To use environment variables as the configuration, make sure the
credentials.json file does not exist in the base folder of the repository.
ENV_VAR_CONFIG_VERSION=2
LOGIN_USER_USERID=1
LOGIN_USER_USER="user1"
LOGIN_USER_NAME="Bob Smith"
LOGIN_USER_HASH="---BCRYPT-HASH-GOES-HERE---"
SERVER_TLS_KEY=/home/user/tls/privkey.pem
SERVER_TLS_CERT=/home/user/tls/fullchain.pem
SERVER_TLS=true
SERVER_PORT=3003
SESSION_SECRET="---COOKIE-SECRET-GOES-HERE---"
To create a new credentials.json file from a full settings template:
# copy example-credentials.json and edit
cp -v example-credentials.json credentials.json
# If multi user system optionally change permission
chmod 600 credentials.jsonIf you are using an external method to manage environment variables, such as running irc-hybrid-client in a container, then use the environment variable template as a guide.
To use environment variables as the configuration, make sure the credentials.json file does not exist in the base folder of the repository.
For configuration using a full settings template:
# copy example-credentials.json and edit
cp -v example-.env .env
# If multi user system optionally change permission
chmod 600 .env- Enter the full file path for TLS certificates. If not using TLS, the file path lines may be omitted and set
tls: falseorSERVER_TLS=false. - Set the port number to a valid integer value. This is the listening port of the web server.
- Set a unique cookie secret to a unique random string (Required).
It is necessary to assign one web page username and password. There is a detailed example in the documentation.
When using credentials.json file or .env file as configuration, this must be done after copying the example-credentials.json into the project folder
The user account used for web page login may be created using one of two javascript files in the tools/ folder. Either the "updateAuthForUser_1.mjs" script maybe be used to add a user account to the credentials.json file, or the "genEnvVarAuthForUser_1.mjs" script may be used to generate the user account for environment variable configuration. The generated environment variables can be copy / paste into the .env file using a text editor.
Option 1 of 2: To add a user account to the credentials.json file.
cd tools/
# fill in user and password when prompted.
node updateAuthForUser_1.mjs
# A revised copy of credentials.json will be displayed after password assignment
cd ..Option 2 of 2: To generate a user account when using environment variable configuration:
cd tools/
# fill in user and password when prompted.
node genEnvVarAuthForUser_1.mjs
# Copy/Paste the environment variable assignments as needed.
cd ..The first time the web server is started, an empty IRC server list will be created automatically as "servers.json" in the base folder of the repository.
Upon the first login to the web page at /irc/webclient.html, the
browser will automatically display an IRC server edit form.
The form is used to define the first IRC server.
Required fields are marked with a colored dot.
Instruction related to the form's fields is located in the form itself using help buttons.
After at least one IRC server has been created, the user may initiate a "Connect" to the IRC network using buttons on the web page. To anyone familiar with IRC, the interface should be familiar. Additionally, there is a server list panel capable to show and edit IRC server definitions.
Optionally, you may edit the IRC server list manually. A file "example-servers.json" can act as a template. The IRC Config section of the documentation (/docs/) includes detail explanation related to manual edit of the server list.
- Configure firewall ports as required.

This section is optional. This repository contains both minified and original un-minified files. The repository can be cloned and deployed as-is, requiring only editing of the configurations files.
In the case where the web page files have been edited, you may want to regenerate a new folder containing replacement minified files for the web page. The there is a separate repository for this called irc-hybrid-client-dev-tools. There are complete instructions for use of this utility in the irc-hybrid-client-dev-tools repository.
A web browser does not consider the server port number when selecting session cookies for HTTP server requests. Running multiple instances of irc-hybrid-client with the same host name, but different server port numbers, can result in the browser submitting multiple session cookies to the web server. Although the instanceNumber configuration property is intended to implement unique cookie names for each instance (port number), unique cookie names WILL NOT prevent the browser from submitting multiple cookies for all sessions that matches the host name. Therefore, it is not recommended to run multiple instances of irc-hybrid client on the same host name unless you understand the security implications associated with cookies and concurrent sessions. This caution does not apply to different users who are connecting from different browser/computer. It does apply to multiple tabs in a one web browser. This setup may be useful for one single user to use multiple browser tabs for simultaneous connection to different IRC networks.
See the login configuration docs for information on use of the instanceNumber property.
The program includes limited support for socks5 proxy connections. See the login config page of the irc-hybrid-client documentation for information.
The irc-hybrid-client program supports optional remote login capability using an external authorization server. An independent authorization server collab-auth was written in parallel with this irc-hybrid-client project. It uses a custom implementation of Oauth 2.0. Further description is available in the Login Config page of the irc-hybrid-client documentation. Only collab-auth is supported. Other generic Oauth 2.0 providers are not supported.
The default irc-hybrid-client configuration uses stand alone internal user authentication by password entry.
