Error response … Continue reading Scaling with Docker Compose and Configuring Load Balancer
GraphQL Day 004 : Subscriptions
So far we have seen Queries and Mutations in GraphQL. It is now time to look into third and final key component of the triage - Subscriptions. Subscriptions allow GraphQL servers to send real time updates to subscribed clients when particular events occur. This allows clients to support real-time functionality by having the servers push the updates … Continue reading GraphQL Day 004 : Subscriptions
Tristate checkbox in Vue JS
HTML 5 does support checkboxes with tri-state (true, false, indeterminate). Indeterminate refers to a state where it is not either checked or unchecked.

Until now, we dealt with, what we could call a readonly system. In other words, we defined queries which does not alter the system. But what if we intent to alter the system, for example, we want to add a new record. This is where mutation comes into the play. The mutation type in GraphQL is used … Continue reading GraphQL Day 003 : Defining Mutations
GraphQL Day 002 : Type Definition basics
Earlier in this series, we will created our first GraphQL Server. If you had noticed we defined our data types as plain C# classes.

Annotation Based … Continue reading GraphQL Day 002 : Type Definition basics

Running MongoExpress in Docker : Solving the connection issue

This is because of one common mistake that developer tends to do (oh yes, I made the mistake) and end up wondering why it doesn't work as desired. Let us write our … Continue reading Running MongoExpress in Docker : Solving the connection issue
Axios, Typescript and Vue 3
In this post, we will aim to create a clean architecture for accessing a rest endpoint, using Axios with Typescript and Vue 3. The key focus here would be to how structure your typescript classes to increase code reuse and isolating the actual axios calls. The approach I follow now is based on building an … Continue reading Axios, Typescript and Vue 3
Child Component Validation using Vuelidate
In this post, we will attempt to validate a form, which contains Child Components while submitting. This is a common scenario that one might face in real life. In this example, we will use the Vuelidate Library for validation. Let us first define the Parent Component. <template> <form @submit.prevent="onManualSubmit"> <label for="name">Name</label> <input id="name" type="text" v-model="name" /> <label for="caption">Caption</label> <input … Continue reading Child Component Validation using Vuelidate
