Error with types in Typescript file using the ES6 module format.

[b4git]

Code (Link to Playground):

import Database from "better-sqlite3";

class DBTester {
db: BetterSqlite3.Database;

  constructor() {
    this.db = new Database(":memory:");
  }
}
new DBTester();

Error:

Cannot find namespace 'BetterSqlite3'.ts(2503)
Public property 'db' of exported class has or is using private name 'BetterSqlite3'.ts(4031)

Possible duplicate of #423 since there is currently no officical TypeScript support. Also DefinitelyTyped/DefinitelyTyped#52163 in case you are using that package.

@b4git, did you arrive at a solution for this?

[CanRau]

For reference, this should work

or alternative

also make sure to install @types/better-sqlite3

[tim-rohrer]

Thanks @CanRau.

I believe I ended up getting this to work:

Import DatabaseConstructor, { Database } from “better-sqlite3”

let db: Database

db = new DatabaseConstructor(“:memory:”)

I do not remember particulars so….

Aah yea nice 👌 only thing if I recall correctly that's needing some tsconfig to support default imports which are kinda non-standard in TS if I'm not mistaken.
