Clapper that can interact with the audience in real time

Finally got a day off on Saturday

Yang Pu still didn't seem to be cleared,2 ~ 4 No. to implement 3天2检

什么是 Claper ？

Clapper Turn your presentation into an interactive one、An engaging and exciting experience. Clapper 能实现：

• Help people present ideas or information,Give them the opportunity to make their presentation unique,And get real-time feedback from your audience.
• Help each participant become an actor in presentations and conferences,and feel important and useful.

Claper 是 Slido 、 AhaSlides 、 Mentimeter 的开源替代品,Can help public speakers and those who must through real-time messaging/Questions and polls for people who make their presentations interactive.

• Slido - Easy-to-Use Q&A and Polling App
• AhaSlides: The Best Free Presentation Software Online
• Mentimeter: Interactive presentation software

ClaperOfficial introductory videoMight make it easier for us to understand what the software is for

Claper Intro - EN

According to Lao Su's understanding,有三个角色：

• 演讲者：创建、Publish the demo document,演讲者;
• 主持人：Operational demo document,Can be the same person as the speaker,也可以不是;
• 参与者：只要有 code You can participate in questions、Listeners who vote etc;

From the perspective of application scenarios, it is mainly a live speech,But combined with remote video conferencing,Remote interaction is also no problem.

命令行安装

在群晖上以 Docker 方式安装.

Official mirrors are not released at docker hub,而是在 ghcr.io,So install it directly from the command line

在 SSH Execute the following commands in sequence on the client

# 下载 mysql 版镜像
docker pull ghcr.io/claperco/claper:latest

如果没有科学上网,Probably won't pull,可以试试 docker 代理网站：https://dockerproxy.com/,But there will be a few more steps

# If you can't pull it, add a proxy
docker pull ghcr.dockerproxy.com/ghcr.io/claperco/claper:latest

# 重命名镜像（If downloaded through a proxy）
docker tag ghcr.dockerproxy.com/ghcr.io/claperco/claper:latest ghcr.io/claperco/claper:latest

# Remove proxy mirrors（If downloaded through a proxy）
docker rmi ghcr.dockerproxy.com/ghcr.io/claperco/claper:latest

You can start using it now docker-compose 安装,将下面的内容保存为 docker-compose.yml 文件

version: '3'

services:
  db:
    image: postgres:14
    container_name: cp-pdb
    restart: always
    volumes:
      - ./data:/var/lib/postgresql/data
    environment:
      - POSTGRES_DB=claper
      - POSTGRES_USER=claper
      - POSTGRES_PASSWORD=claper

  claper:
    image: ghcr.io/claperco/claper:latest
    container_name: cp-claper
    restart: always
    depends_on:
      - db
    ports:
      - '4000:4000'
    environment:
      - DATABASE_URL=postgresql://claper:[email protected]:5432/claper
      - SECRET_KEY_BASE=zrSGxcmp9NVexg9gWK7KozoX3sw7FWkvbwBHePugtD6L5VNT7Wnra5EYuo44ycaE
      - ENDPOINT_HOST=192.168.0.197
      - ENDPOINT_PORT=4000
      - MAIL_TRANSPORT=smtp
      - [email protected]
      - MAIL_FROM_NAME=laosu
      - SMTP_RELAY=smtp.88.com
      - [email protected]
      - SMTP_PASSWORD=<Your third-party mail client password>
      - SMTP_PORT=25
      - SMTP_SSL=false
      #- SMTP_AUTH=if_available
      #- SMTP_TLS=if_available

环境变量的简单说明：

范围	默认	描述
DATABASE_URL	-	Postgres 数据库连接字符串,不要改;
SECRET_KEY_BASE	-	缺省为 64 位字符串
ENDPOINT_HOST	-	主机 IP,Please follow your Synology IP 修改
ENDPOINT_PORT	-	主机端口,要跟随 ports Set the native port;
MAIL_TRANSPORT	local	Define how emails are sent
MAIL_FROM	-	Email address for sending emails
MAIL_FROM_NAME	-	The name used to send the email
SMTP_RELAY	-	SMTP 中继服务器
SMTP_USERNAME	-	用于 SMTP 连接的用户名
SMTP_PASSWORD	-	用于 SMTP 连接的密码
SMTP_PORT	-	SMTP 服务器端口
SMTP_SSL	true	SMTP 是否启用 SSL
SMTP_AUTH	always	SMTP 验证
SMTP_TLS	always	SMTP 是否启用 TLS

For more environment variables, please see the official documentation：https://docs.claper.co/configuration.html#environment-file

然后执行下面的命令

# 新建文件夹 claper 和 子目录
mkdir -p /volume2/docker/claper/data

# 进入 claper 目录
cd /volume2/docker/claper

# 将 docker-compose.yml 放入当前目录

# 一键启动
docker-compose up -d

在浏览器中输入 http://群晖IP:4000 就能看到主界面

如果你是 参与者,After receiving the invitation,直接将 code 填入 # 号之后,点 Join 就可以加入;

To log in just enter your email address,After entering your email,点 Send link by email

If there is no problem with the settings of the sending mailbox,You should receive an email shortly
