Evolutility-UI-React

Evolutility-UI-React is a set of model-driven views to Browse, Edit, List, Cards, and Charts data by writing models rather than code.

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/.

For 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 Meaning Example
apiPath Path to REST API (can use "proxy" from package.json). "/api/v1/"
filesUrl Path to upload files to. "http://localhost:3000/pix/"
pageSize Pagination 50
locale Date format (no translation yet) en/fr
wTimestamp Add timestamp columns u_date and c_date to track record creation and update times. true

Views

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

Evolutility-UI-React provides 2 types of view:

Notes: Views for actions will come later.

A large part of the API (methods, options and events) is common to all views. Some views have additional API.

Views for One object

Browse

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

Browse

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

View: http://localhost:3000/comics/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.js

View: http://localhost:3000/comics/edit/{id}

Views for Many objects

List

Gives a tabular view of a collection.

List

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

View: http://localhost:3000/comics/list

Cards

Shows records side by side as cards.

Cards

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

View: http://localhost:3000/comics/cards

Charts

Draws charts about the collection (currently bars and pies).

Charts

Code: /src/components/views/many/Charts.js

View: http://localhost:3000/comics/charts

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/many/Stats.js

View: http://localhost:3000/comics/stats

Models

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

groups Array of Groups. If not provided a single group will be used.
collections Array of Collections.
titleField Field id for the column value used as record title. titleField can also be a function.
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.
object Model id for the object to link to (only for fields of "lov" type).
inMany Determines if the field is present (by default) in lists of records.
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 Prevent the field to have a charts (only necessary for fields of type integer, decimal, money, boolean, list of values which are "chartable").
unique Values must be unique (not implemented yet).

Group

Groups are used to visually divide Fields (in Edit and Browse views).

Property Meaning
id Unique key for the group. It is optional.
type Type of fields group. Only "panel" is currently supported (tab and other types of groups will be added later).
label Group title displayed in the group header.
fields Array of field ids.
width Width (in % of the container total width).
header Text to be displayed at the top of the group (just below the group title).
footer Text to be displayed at the bottom of the group.

Note: Groups are optional. By default a single group holds all fields.

Collection

Multiple details tables can be specified with "collections".

Property Meaning
id Unique key for the collection.
title Collection title.
object Model.id for the Object to link to.
fields Array of fields (objects or ids). Fields in collections do not need all properties of Fields in objects.
header Text to be displayed before the collection.
footer Text to be displayed after the collection.

Sample model using collections: Wine Cellar.

Sample model

The following example is the model for a simple graphic novels inventory app.

module.exports = {
