The best practice for running Wechaty Docker/NPM is using a VPS(Virtual Private Server) outside of China, which can save you hours of time because npm install and docker pull will run smoothly without any problem.
The following VPS providers are used by the Wechaty team, and they worked perfectly in production. You can use the following link to get one in minutes. Also, doing this can support Wechaty because you are referred by us.
| Location | Price | Ram | Payment | Provider |
|---|---|---|---|---|
| Singapore | $5 | 512MB | Paypal | DigitalOcean |
| Japan | $5 | 1GB | Paypal | Linode |
| Korea | $10 | 1GB | Alipay, Paypal | Netdedi |
| Singapore | $3.5 | 512MB | Alipay, Wechat | Vultr |
In 2017 ...
Huan's daily life/work depends on too much chat on wechat.
- Almost 14,000 wechat friends in May 2014, before wechat restricts a total number of friends to 5,000.
- Almost 400 wechat rooms, and most of them have more than 400 members.
Can you imagine that? He was dying...
So a tireless bot working for me 24x7 on wechat, monitoring/filtering the most important message is badly needed. For example, it highlights discussion which contains the KEYWORDS which he want to follow up(especially in a noisy room). ;-)
At last, It's built for huan's personal study purpose of Automatically Testing.
