Property 'catch' does not exist on type 'Promise<void>'
According to DefinitelyTyped's mongoose.d.ts
/** * To assign your own promise library: * * 1. Include this somewhere in your code: * mongoose.Promise = YOUR_PROMISE; * * 2. Include this somewhere in your main .d.ts file: * type MongoosePromise<T> = YOUR_PROMISE<T>; */So, your main .d.ts file would look like the following:
/// <reference path="globals/bluebird/index.d.ts" />/// <reference path="globals/mongoose/index.d.ts" />type MongoosePromise<T> = bluebird.Promise<T>;
I've ended up doing this extending the mongoose module:
declare module "mongoose" { import Bluebird = require("bluebird"); type MongoosePromise<T> = Bluebird<T>;}See my answer here : Mongoose Promise with bluebird and typescript
