Evolutility-UI-React ·

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:

Views for One - a single record: Browse, Edit.
Views for Many - a collection of records: List, Cards, Charts, Stats.

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.

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.

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.

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

Route: "/{entity}/list"

Cards

Shows records side by side as 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).

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.

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.

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).

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

Property	Meaning
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.

Property	Meaning
id	Unique key for the field (can be the same as column but doesn't have to be).
type	Field type to show in the UI. Possible field types: boolean (yes/no) date decimal document email image integer json lov (list of values) money text textmultiline time url
label	Field description (displayed with an asterisk for required fields).
labelShort	Optional shorter version of the labels (used in List and Cards views).
required	Determines if the field is required for saving.
readOnly	If set to true, the field value cannot be changed.
defaultValue	Default field value for new records.
format	Field format (using moment for date values and numeral for numeric values).
max, min	Maximum/Minimum value allowed (only applies to numeric fields).
maxLength, minLength	Maximum/Minimum length allowed (only applies to text fields).
regExp	Regular expression used to validate the field value.
list	List of items in the dropdown as an array of id-text objects (only for fields of "lov" type). If ommited, the list will be retrieved in the first query by id on that object.
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).
aggregate	Optional overide for aggregation name in charts (only for "lov" fields).
inMany	Determines if the field is present (by default) in lists of records.
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").
noStats	Exclude field from Stats.

Field Group

Field Groups are used to separate Fields into panels in the 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).
help	Optional help tooltip text.
header	Optional text displayed at the top of the group (just below the group title).
footer	Optional text displayed below the group.

Notes:

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

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