Model-driven CRUD UI for Hasura GraphQL.

Evolutility-UI-React · GitHub license npm version

Evolutility-UI-React is a set of model-driven views to Browse, Edit, List, Cards, Charts, Statistics, and API Documentation. With it you can easily build CRUD applications by writing models rather than code. It works with REST APIs (using Evolutility-Server-Node) or GraphQL (using Hasura). No hand-coding is necessary.

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.


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 REST API (can use "proxy" from package.json). "http://localhost:2000/api/v1/"
apiPathGraphQL Path to GraphQL API. "https://localhost:2000/v1/graphql"
apiType Type of API. "rest" or "graphql"
filesUrl Path to upload files to. "http://localhost:3000/pix/"
pageSize Page size in pagination. 50
locale Date format (no translation yet). en/fr
queryModels Get models from JSON files or from the database through the API.
wTimestamp Add timestamp columns u_date and c_date to track record creation and update times. true


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.
  • Views for documentation: REST API Doc.

Evolutility can be configured to use REST (using Evolutility-Server-Node) or GraphQL (using Hasura).

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

Views for One object

Browse - Edit


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


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

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


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.js

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

Views for Many objects

List - Cards - Charts - Stats


Gives a tabular view of a collection.


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

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


Shows records side by side as cards.


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

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


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/charts/Charts.js

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

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


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


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

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

Views for Documentation


Documentation and test for the model's REST endpoints.


Code: /src/components/views/doc/Api.js

View: http://localhost:3000/comics/api

Note: This view is only useful when using REST. For GraphQL third party tools like GraphiQL can be used.


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.


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 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".


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
  • datetime
  • decimal
  • document
  • email
  • image
  • integer
  • json
  • lov (list of values)
  • list (multiselect)
  • 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.
max, min Maximum/Minimum value allowed (only applies to numeric fields).
maxLength, minLength Maximum/Minimum length allowed (only applies to text 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 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.
unique Requires value to be unique (not implemented yet).


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).
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.


  • Groups are optional. By default a single group holds all fields.
  • Groups are positioned based on their "width" property the same way than fields are positioned inside groups.


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 can be field objects or just ids of fields in the collection's object.
header Text to be displayed before the collection.
footer Text to be displayed after the collection.

Sample model using collections: Wine Cellar.
