Please implement the code to export many-to-many relationships in DBML.
You can implement it similar to this function:
| break; | ||
|
|
||
| case 'sqlite': | ||
| res = SqliteExporter.export(normalizedModel); |

It would be best if you could use the same class name SQLiteExporter as the class definition to make it easy to debug in the future.

I found that SQLite does not support the ALTER TABLE ... ADD FOREIGN KEY ... syntax (see: https://www.sqlite.org/omitted.html).
I believe that we can move the relationship definitions in the CREATE TABLE ... statement.
| Table "order_items" { | ||
| "order_id" integer | ||
| "product_id" integer | ||
| "quantity" integer [default: 1] | ||
| } |

Although the DBML syntax is correct, this mapping table should be defined after the products table so that when we export to SQLite, if the foreign key constraints are added in the CREATE TABLE "ORDER_ITEMS" ... statement, the exported SQL is still correct.

Please export the indexes.
| static getTableContentArr (tableIds, model) { | ||
| const tableContentArr = tableIds.map((tableId) => { | ||
| const fieldContents = SQLiteExporter.getFieldLines(tableId, model); |

This function needs to export the composite primary keys. You can refer to
to implement it

Hey @nguyenalter I'm picking this up — just checking in to see if you're still around to review and merge when done. |
