waline-light

A high-performance Waline comment system implemented in Rust.

Introduction

Waline-light is a high-performance Rust implementation of the Waline comment system, using 95% less memory than its Node.js counterpart and serving as an efficient alternative for resource-constrained servers.

In my Ubuntu server, the waline-light requires only about 5612Kb=5.48MB of memory

• Extremely low memory usage: Just 1/25 of the Node.js version's memory footprint.
• Zero dependency deployment: No need to install Node.js environment, just an executable file is enough.
• Easy replacement: Implements most of the necessary apis of the original Waline.
• Synchronous update: Keeping pace with the original Waline's evolution.

Usage

Run from an executable file

From GitHub Releases to download the binary file is appropriate for your platform. Examples of Linux use:

# Setting environment variables
export DATABASE_URL=sqlite:///path/to/waline.sqlite?mode=rwc
export JWT_TOKEN=your_secret_key
export SITE_NAME=your_site_name
export SITE_URL=your_site_url

# Start
./waline-light

Docker

services:
  waline:
    image: zhx57/waline-light:latest
    container_name: waline-light
    ports:
      - "8360:8360"
    volumes:
      - waline-db:/app/db
    environment:
      - DATABASE_URL=${DATABASE_URL:-sqlite:////app/db/waline.sqlite?mode=rwc}
      - JWT_TOKEN=${JWT_TOKEN}
      - SITE_NAME=${SITE_NAME}
      - SITE_URL=${SITE_URL}
    restart: unless-stopped

volumes:
  waline-db:
    driver: local

if you want to use other databases, you only need to add -e DATABASE_URL environment for coverage

Shuttle

waline-light supports deployment on Shuttle by first cloning the shuttle branch to the local using the following command

git clone -b shuttle https://github.com/zhx57/waline-light.git

Then, create a .shuttle.env environment variable in the project root to configure waline-light

Finally, in accordance with the Shuttle steps for deployment

LeanCloud

When LeanCloud is used to pull the warehouse directly for deployment, the branch needs to enter "leancloud"

If SQLite is used as the data store, the environment variable DATABASE_URL should be filled with sqlite://./waline.sqlite? mode=rw. When deploying with LeanCloud, a new SQLite file is included each time, so it is important to export the data before redeployment and import the data after redeployment when upgrading the waline-light for redeployment

Configuration

Configure waline-light with environment variables:

Environment variable	Description	Require	Default
DATABASE_URL	SQLite and MySQL/MariaDB are supported. Compile features can be added to support PostgreSQL at any time. protocol://username:password@host/database	✅	-
JWT_TOKEN	A random string is used to generate the JWT Signature key	✅	-
SITE_NAME	Site name	✅	-
SITE_URL	Site url	✅	-
SERVER_URL	Custom Waline server address		auto
HOST	listening host		127.0.0.1
PORT	listening port		8360
WORKERS	Worker thread		1
LEVELS	Give each user a rating label based on the number of comments		-
SMTP_SERVICE	SMTP mail service provider: QQ，GMail，126，163		-
SMTP_HOST	SMTP server address		-
SMTP_PORT	SMTP server port		-
SMTP_USER	SMTP username		-
SMTP_PASS	SMTP Password		-
AUTHOR_EMAIL	The blogger’s email, used to judge whether posted comment is posted by the blogger.If it is posted by the blogger, there will be no reminder notification		-
IPQPS	IP-based comment posting frequency limit in seconds. Set to 0 for no limit		60

DISALLOW_IP_LIST	If a comment ip match this list, 403 status code is returned. such as 8.8.8.8,3.3.3.3
SECURE_DOMIANS	Secure domain settings. Requests from other domain will receive 403 status code. It supports String, Regexp, and Array type. Leaving this config means that all domain referrer are allowed

DISABLE_REGION	wether hide commenter's region. Default value is false		false
DISABLE_USERAGENT	wether hide the user agent of commenter. Default value is false		false
IP2REGION_DB	customized IP query library path. The waline-light does not contain xdb files and needs to be provided manually
