A Node-Red node to read and write a local sqlite database.
Run the following command in your Node-RED user directory - typically ~/.node-red
npm i --unsafe-perm node-red-node-sqlite
Note: 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
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
sqliteReconnectTime: 20000,
