How to define indexes for Mongodb collections in Dove (v5)

[nathanbrizzee-cdcr]

I was wondering what the best (Feathers) way is to define Mongodb collection indexes in the Dove release (v5)? In v4, indexes are defined in the model file. With the new schemas / resolvers files, should there be something in the migrations folder for Mongo? Since Mongo creates collections on the fly, the indexes need to be applied after creation. Is this something we should do in the constructor of the class?

Late answer:

for example in the users.class

import { MongoDBService } from "@feathersjs/mongodb";

export class UserService extends MongoDBService {}

export const getOptions = (app) => {
    return {
        paginate: app.get("paginate"),

        Model: app.get("mongodbClient").then((db) => {
            const model = db.collection("users");

            // your indexes
            model.createIndex({ email: 1 }, { unique: true }).catch(() => {});

            return model;
        }),
    };
};
