Package Exports
- loopback-connector-sqlite3
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (loopback-connector-sqlite3) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

The SQLite3 Connector module for for loopback-datasource-juggler.

Discovering Models
The SQLite3 connector does not currently support discovery of models.
Model definition for SQLite3
The model definition consists of the following properties:
- name: Name of the model, by default, it's the camel case of the table
- properties: Property definitions, including default value mapping
{"name": "Inventory", "options": {
"idInjection": false,
}, "properties": {
"id": {
"type": "String",
"required": false,
"length": 64,
"precision": null,
"scale": null
},
"productId": {
"type": "String",
"required": false,
"length": 20,
"precision": null,
"scale": null,
"id": 1
},
"locationId": {
"type": "String",
"required": false,
"length": 20,
"precision": null,
"scale": null,
"id": 1
},
"available": {
"type": "Number",
"required": false,
"length": null,
"precision": 32,
"scale": 0
},
"total": {
"type": "Number",
"required": false,
"length": null,
"precision": 32,

Type Mapping
- Number
- Primary key is stored as INTEGER
- Others are stored as REAL
- Boolean
- Stored as INTEGER 1 or 0
- Date
- Stored as INTEGER (Millis since Jan 01 1970 00:00:00 0000)
- String
- Complex types (GeoPoint, Point, List, Array, Object, Sub-models)
- Stored as TEXT in JSON form
- JSON
- Stored as TEXT
SQLite3 does not enforce types. I.e. any data can be stored in any column regardless of definiton. This connector attempts to check for invalid Date, Number and JSON types.
Auto Migrate / Auto Update
The SQLite3 connector does not currently support auto-migrate or auto-upgrade.
