A Node-Red node to read and write a local sqlite database.
Based on the basic node-red-sqlite, but this allows queueing of messages and dynamic databases.
Run the following command in your Node-RED user directory - typically ~/.node-red
npm i --unsafe-perm node-red-contrib-queued-sqlite
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.
All queries are automatically queued and dequeued per database.
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.
You can choose a database in the configuration or provide it in msg.database.
The reconnect timeout in milliseconds can be changed by adding a line to settings.js
sqliteReconnectTime: 20000,
