Welcome to Spool Node
node-red-contrib-spool
一个 Node-RED 节点，用于存储未传送的出站消息并将其从串行设备传送到代理。
Overview
该节点的主要目标是通过将其存储在 sqlite 数据库中并在代理处于活动状态或重新连接后将消息重新发送到代理，以防止在代理停机期间丢失任何出站消息。 在 Linux、Windows 和 MacOS 等不同操作系统上安装相对容易。
Installation
按照说明安装 node-red-contrib-spool
> cd $HOME/.node-red
> npm install @aansi/spool
或者 您可以按照 Node-RED 入门文档 中的添加节点说明进行操作。
Usage
要实施此节点，请启动或重新启动 Node-RED（请参阅文档 了解入门信息）。 假脱机节点的示例流程如下所示。 您还可以通过复制给定的 Example（json 格式）并将其导入您的 Node-RED。
TODO
根据用户输入创建数据库
实施其他消息协议，如 UDP

Welcome to Spool Node
node-red-contrib-spool
A Node-RED node for storing and delivering the undelivered outbound messages from the serial devices to the broker.
Overview
The main objective of this node is to prevent the loss of any outbound messages during the brokers' downtime by storing it in the sqlite database and re sending the messages to the broker once it is active or reconnected. It is relatively easy to install on different operating system such as Linux, Windows and MacOS.
Installation
Install node-red-contrib-spool by following the instructions
> cd $HOME/.node-red
> npm install @aansi/spool
Or You can follow the adding nodes instructions from the Node-RED Getting Started Documentation.
Usage
To implement this node, start or restart the Node-RED (See the Documentation for getting started). The example flow for the spool node is illustrated below. You can also re-create this flow by copying the given Example (json format) and importing it in your Node-RED.
TODO
Creation of database based on user input
Implementation of other messaging protocol such as UDP
