node-red-node-sqlite
|
|
====================
|
|
|
|
A Node-Red node to read and write a local sqlite database.
|
|
|
|
Install
|
|
-------
|
|
|
|
Run the following command in your Node-RED user directory - typically `~/.node-red`
|
|
|
|
npm i --unsafe-perm node-red-node-sqlite
|
|
|
|
**Notes**:
|
|
|
|
- Version 1.x requires nodejs v12 or greater.
|
|
- The install process requires a compile of native code. This can take 15-20 minutes on devices like a Raspberry Pi - please be prepared to wait a long time. Also if node.js is upgraded at any point you will need to rebuild the native part manually, for example.
|
|
|
|
cd ~/.node-red
|
|
npm rebuild
|
|
|
|
Usage
|
|
-----
|
|
|
|
Allows basic access to a Sqlite database.
|
|
|
|
This node uses the **db.all** operation against the configured database.
|
|
This does allow INSERTS, UPDATES and DELETES.
|
|
|
|
By it's very nature it is SQL injection... so *be careful* out there...
|
|
|
|
`msg.topic` must hold the *query* for the database, and the result is returned in `msg.payload`.
|
|
|
|
Typically the returned payload will be an array of the result rows, (or an error).
|
|
|
|
You can load sqlite extensions by inputting a `msg.extension` property containing the full path and filename.
|
|
|
|
The reconnect timeout in milliseconds can be changed by adding a line to **settings.js**
