Evolutility-UI-React · GitHub license npm version

Evolutility-UI-React is a set of model-driven views to Browse, Edit, List, Cards, Charts, Stats, Overview, and Activity.

With it you can easily build CRUD applications by writing models rather than code. It uses Hasura GraphQL backend. No hand-coding is necessary!

Check out the live demos.

Installation

Download or clone from GitHub.

# To get the latest stable version, use git from the command line.
git clone https://github.com/evoluteur/evolutility-ui-react

or use the npm package:

# To get the latest stable version, use npm from the command line.
npm install evolutility-ui-react

In the Evolutility-UI-React directory, use the command line to type the following:

# Install dependencies
npm install

# Run the node.js server
npm start

In a web browser, go to the url [http://localhost:3000/ the REST endpoints, you also need to install and run Evolutility-Server-Node which provides the matching REST endpoints based on the same metadata.

Configuration

Configurations options are specified in the file /src/config.js. They apply to all apps (app specific options are specified in models).

Option Description Example
apiPath Path to GraphQL API. "https://myapp.hasura.app/v1/graphql"
adminSecret Token for Hasura.
useCache Enable/disable data caching. true
cacheDuration Cache duration in seconds. 120 (for 2 minutes)
filesUrl Path to upload files to. "/pix/"
pageSize Page size in pagination. 50
withActivity Tracks and shows records activity (last visited and most visited). Currently implemented w/ the browser's localStorage, it will be moved to the server later. true
queryModels Get models from JSON files or from the database through the API. (not implemented yet)
withTimestamp Tracks and shows timestamp for creation date and last update for every record. The DB tables need timestamp columns "updated_at" and "created_at" for the feature to work. (partial implementation) true

Views

For any object, a single model defines UI elements across views in a simple declarative way.

Evolutility-UI-React provides different types of view:

Evolutility uses GraphQL with Hasura.

Notes: Views for actions (search, filter, export) will come later.

Views for One object

Browse - Edit

Browse

Shows all fields for viewing (read only). Fields are grouped in panels.

Browse

Code: /src/components/views/one/Browse/Browse.jsx

Route: "/{entity}/browse/{id}"

Edit

This view shows all fields for edition to create or update records. It automatically performs validation based on the model. Fields are grouped in panels and tabs.

Edit

Code: /src/components/views/one/Edit/Edit.jsx

Route: "/{entity}/edit/{id}"

Views for Many objects

List - Cards - Charts - Stats

List

Gives a tabular view of a collection.

List

Code: /src/components/views/many/List/List.jsx

Route: "/{entity}/list"

Cards

Shows records side by side as cards.

Cards

Code: /src/components/views/many/Cards/Cards.jsx

Route: "/{entity}/cards"

Charts

Draws charts about the collection. Currently bars and pie charts are implemented, a list with count and percentages is also available. Only provided for fields of types like boolean, lov, integer, decimal, date... (not text or textmultilines).

Charts

Code: /src/components/views/analytics/Charts/Charts.jsx

Route: "/{entity}/charts"

Note: The "Charts" view is currently only implemented for REST, not available with GraphQL yet.

Stats

Display last update, number of updates in the last week, and for numeric fields the min, max, count, average.

Stats

Code: /src/components/views/analytics/Stats/Stats.jsx

Route: "/{entity}/stats"

"Comfort" views

Display a summary of the object and the latest activity on it.

Overview

Display a summary of the object and the latest activity on it.

Overview

Code: /src/components/views/comfort/Overview/Overview.jsx

Route: "/{entity}/"

Activity

Show list of "last visited" and "most visited" records for the object (stored in the browser's localStorage).

Activity

Code: /src/components/views/comfort/Activity/Activity.jsx

Route: "/{entity}/activity"

Models

Each model describe an object and its list of fields. A single model is used for all views (Browse, Edit, List, Cards...).

For any object, all UI views (List, Cards, Edit, Charts...) share the same model. All Fields are present in the Edit and Browse views. Fields can be flagged with "inMany" to be included in the List and Cards views, or "noCharts" and "noStats" to be excluded from the Charts or Stats views.

Object

id Unique key to identify the entity (used in route and as API parameter).
qid Entity ID used in GraphQL (may be different from id in route).
icon Icon file name for the entity (example: "cube.gif").
name Object name (singular).
namePlural Object name (plural).
title Application name.
fields Array of Fields.
groups Array of Groups. If not provided a single group will be used.
collections Array of Collections.
titleField Id of the field which value is used as record title. titleField can also be a function.
titleFunction Function to calculate the record title based it's data. Example: titleFunction = (data, model) => data.firstname + " " + data.lastname;
defaultViewOne To have List and Cards link to Edit instead of Browse, set defaultViewOne="edit".

Field

Objects have fields.

lovIcon Set to True to include icon with LOV items(only for fields of "lov" type).
object Model id for the object to link to (only for fields of "lov" type).
chartObject Optional overide for object name in charts (only for "lov" fields).

inSearch Determine if the field is used in text searches.
height For fields of type "textmultiline", number of lines used in the field (in Browse and Edit views).
width Field width in Browse and Edit views (in percent of parent width).
help Optional help on the field.
chartType Default charts type used for the field ("Bars", "Pie", or "Table"). "Bars" is used if not specified.
noCharts Exclude field from charts (only applies to fields of type integer, decimal, money, boolean, list of values which are "chartable").

  1. You can signup for a free account or host it yourself (Quickstart Hasura CLI).
  2. Add a Postgres database to your Hasura setup.
  3. Add the demo tables by running the SQL script evol-db-schema.sql.
  4. Populate your database with sample data by running evol-db-data.sql
