The text explains how to create a custom query builder using Cube client libraries in Vue.js, building on a previous tutorial for React. It describes how developers can leverage the scoped slots technique to implement their own render logic, offering flexibility in creating a tailored UI with a minimal API. The tutorial guides users through setting up a demo backend with Cube, using a PostgreSQL database, and configuring the environment. It then details how to set up a Vue project with Vuetify for UI components, and how to incorporate Cube Vue client, Vue Chartkick, and Chart.js for rendering data visualizations. The tutorial demonstrates creating a simple query builder that allows users to select metrics and dimensions for grouping, culminating in a functional application where users can test their queries and visualizations. Additional features such as filters, date ranges, and chart type selectors are highlighted, with references to further examples and source code available on Github, encouraging user feedback through a Slack Community.
