Let's consider the following scenario:
const client: Client | boolean = await db.connect()
if (client === false) {
return
}
await start(client)
The function db.connect() returns either a Client on successful connection or false in case of failure.
The function start requires a parameter of type Client:
const start = async (dbClient: Client): Promise<void> => {
However, an error occurs when using await start(client):
Argument of type true | Client is not assignable to type Client
To address this issue, one option could be to modify the types in start to handle both Client and boolean, but this approach may lead to complications in the future.
An alternative suggestion is to adjust the return value of connect to an object like this:
{
connected: boolean,
client: client,
}
Would this solution be more suitable for this situation?
