Bootstrap with Bootswatch

I think I have to employ Bootstrap for the UI. I'm spinning my wheels trying to pick compatible colors--that's just a waste of time. I came across Bootswatch, which has a bunch of Bootstrap templates.

I like this one: https://bootswatch.com/cerulean/

This should be easy: https://bootstrap-vue.js.org/

First: npm install vue bootstrap-vue bootstrap

Then:

// app.js
import Vue from 'vue'
import BootstrapVue from 'bootstrap-vue'

Vue.use(BootstrapVue)

This is what Vue plugins look like (fontawesome does the same thing):

// This imports all the layout components such as <b-container>, <b-row>, <b-col>:
import { LayoutPlugin } from 'bootstrap-vue'
Vue.use(LayoutPlugin)

CSS for Tables

Tables still have a place--for tabular data. Duh. Such as the Companies table in FDB. But I had to remember the CSS around tables. First, the basic structure: table thead tr th tbody tr td Table border-collapse: { separate (default) | collapse } border-spacing: { #both | #horiz #vert } - default is 1px empty-cells: { show (default) | hide } table-layout: { auto (default) | fixed } - fixed is like !important for widths For a responsive table, put it inside a container (e.g., div) with overflow-x: auto; Width, height, border can be applied to table, th and td--not tr, thead or tbody. Cells th and td tags. CSS doesn't seem to like naked th and td. Prefer table td or table th selectors. text-align: { left | center | top } vertical-align: { top | bottom | middle } padding (margin doesn't do anything; use border-spacing) border-bottom: - for just horizontal lines between rows Rows For a mouse-over to select whole rows at a time: tr:hov

A JSON Db Product?

The last post "solved" the problem of many-to-many table joins by papering over the association table with a RESTful JSON interface. As long as we're using JSON, we might as well take advantage of multi-valued table cells. I'm naturally wondering where this leads. JSON identifiers and types and SQL identifiers and types overlap so much that their intersection is a useful subset. Camel-case fields in string, number, bool flavors. Many-to-many occurs often in the world: Students in Classes Actors in Films (musicians on recorded songs) Parts in Assemblies Customers and Products (joined by Orders) The generalized description is that a Table requires a unique identifier for each row. Tables list students, actors, films, customers, and so on. An Association Table is has two or more foreign keys that match unique identifiers in other tables. The knowledge of how a FK maps to a specific Table is baked in--we wouldn't want a "table name" column.

GraphQL is the many-to-many solution

Exactly! Regular readers of this blog (me) will appreciate my stumbling attempts to pre-define a REST interface that supports many-to-many interfaces. GET a class, for example, and the return includes an array of the students in that class. In this context, we don't want a full Student record, just the Student's name and Id, for example. With a REST interface, the server writer has to guess how to abbreviate the Student record. GraphQL fixes that. The front end requests just the data it wants. If we want a list of the students in a class and the assigned roommates for that student...we can do that! A lot of my prototype REST service is hardwired--not single tables, so much, but the many-to-many stuff certainly. There was a certain amount of work implementing the simple router ("/table/recordno"). GraphQL means throwing a lot of that away, but I can see immediately that GraphQL's approach is what I want. My schema tables (implementing INSERT and UPDATE) look
