lowdb - how to query multiple records?

Asked 2022-Mar-03 at 05:32

I'm using https://github.com/typicode/lowdb for a small project. I need a query which searches multiple records and returns each record it finds as an array.

For example, for a db such as:

NOTE: I don't use LowDB

Judging by the docs, I think it's not possible to find multiple records in LowDB. Instead, you can use the Array#filter method.

QUESTION

Dictionary type in TypeScript not accepting a hash of methods

Asked 2021-Aug-09 at 12:30

I'm importing types from lowdb via @types/lowdb, and when using their mixins() method to configure mixins on a store, it complains that the argument I'm passing doesn't type-match:

Argument of type 'Map' is not assignable to parameter of type 'Dictionary<(...args: any[]) => any>'. Index signature is missing in type 'Map'.ts(2345)

I assumed that the type accepted by the mixins method was essentially a map of functions indexed with a string. So figured that Map would be an acceptable thing to pass it. The context:

QUESTION

Vue.js reativity features in backend application?

Asked 2021-Mar-14 at 15:44

I'm wondering if there's someone knowledgeable in Vue(2 or 3)'s reativity that might be able to answer this question and explain reasons.

This is regarding features such as data() reactivity (getters & setters), computed properties, a global Vue instance, and even a Vuex store.

Is there a way I could tap into just these non-browser javascript features for use in a backend-only Node.js application?

I need a way to have a global store holding temporary data that can update "components" in other files via mapState/mapGetters.

I'm using lowdb currently for this because it suits my needs in terms of shapeable JSON objects, where something like redis is key:value-only. (Don't want to get into a more complex redis/rejson setup.)

Basically I need a globally accessible relatively-full-featured reactivity system on the backend, without global variables or needing to set up a custom Rxjs system, which is a bit over my head and will take too much momentum away from my goals, time-wise.

I'd appreciate any input. Thanks 🙂

Vue is designed to run inside Node to support SSR (server side rendering). There is already a good post here on SO with simple sample for Vue 2 (using Vue + Vuex)

But it seems overkill to me. If you want something much simpler and lightweight, you can use package @vue/reactivity which is normally part of the Vue 3 but can be used completely standalone. It is basically Vue 3 reactivity system based on JS proxies

Why would I choose this approach:

No Vue 2 Change Detection Caveats
More "functional" API (designed for their new Composition API) with much better support for TypeScript and type inference (even without TS)
I think Vuex API is super bad (using string constants for data mapping - especially with modules. It's pain...)

As it is part of Vue 3, you can use it's documentation:

Return to parent object in lodash chaining "_.chain()"

Short answer

If your goal is to make your code as good looking as possible, I would recommend you use lodash-id, and its updateById function. I introduce all kind of possible solutions in my long answer, but personally I would avoid chaining directly, and instead do something like:

ANSWER

Answered 2020-Aug-30 at 06:22

Your problem is the vue.config.js only exports the last object, each module.exports overrides previous exports.

The other problem you may have is that you disabled nodeIntegration, thus process will indeed be undefined unless you enable webpacks definition.

Edit: To make require available on the renderer, you need to enable nodeIntegration in your background.ts file or disable it in vue.config.js.
