Adding New Page

This tutorial below explains backend and frontend development of adding a new page/process step by step.

UI / Frontend​

You'll generally be dealing with 4 files in src folder for a standard page which you can manage easily with JSON objects without coding javascript or typescript.

1) Menu Item Component​

views/Routes/YourPageName/YourPageNamePageConfig.js

It includes a generic component to be used in pages.js for menu. You'll just need to import related SamplePageConfig.js

import React from 'react';
import BasePage from '../../../components/BasePage';
import PageConfig from './SamplePageConfig'; // Edit this line

export default class SampleUserCls extends React.PureComponent {
render() {
return (
<BasePage config={PageConfig} />
)
}
}

2) Page Config​

views/Routes/YourPageName/YourPageNamePageConfig.tsx

Page structure specifying title, tabs, resource code, CRUD service urls, buttons and so on.

import { IPageConfig, Methods, pageConfigWrapper, Tables } from '../../../common/typeConfig';
import { getLocalizedText } from '../../../common/localizationManager';
import Constants from '../../../common/constants';

import SamplePage from '../../../entities/SamplePage';

const { LIST, GET, INSERT, UPDATE, DELETE, EXPORT, IMPORT } = Methods;

let pageConfig: IPageConfig = {
headerTitle: getLocalizedText('SEARCH_LIST_TITLE'),
tabs: [
{
title: 'User Title', // Tab title
type: SamplePage,
resourceCode: 'SamplePage_Resource_Code',
editOnModal: false, // Behaviour when clicked on a row of the table
list: {
url: `${Constants.ApiURL}/sampleService/list`
},
get: {
url: `${Constants.ApiURL}/sampleService/get`
},
insert: {
url: `${Constants.ApiURL}/sampleService/insert`
},
update: {
url: `${Constants.ApiURL}/sampleService/update`
},
delete: {
url: `${Constants.ApiURL}/sampleService/delete`
},
import: {
url: `${Constants.ApiURL}/sampleService/bulkSave`
},
allowedMethods: // Allowed buttons/actions of the table
[
LIST,
GET,
INSERT,
UPDATE,
DELETE,
IMPORT,
EXPORT,
DUPLICATE
],
},
],
};

export default pageConfigWrapper(pageConfig);

3) Model Class​

entities/YourPageNamePage.ts

Simply consists of the model class as JSON specifying components, groupings, rules, validations and so on.

import TableFormatters from '../common/TableFormatters';
import { Regexes } from '../common/validations';
import { IType, ComponentType, Visibility, typeConfigWrapper, IGroup, CaseStyles, LabelPositions } from '../common/typeConfig';
import { ParameterOptionTemplate } from '../common/typePresets';
import { getLocalizedText } from '../common/localizationManager';

const { TABLE, FORM, FILTER, BG_FILTER, BG_FORM, FK_FILTER, FK_FORM } = Visibility;

// We have 3 groups to gather components in order to have a better look & feel
let group1: IGroup = { title: 'User Info', columnSize: { all: 4 } };
let group2: IGroup = { title: 'Job Info', columnSize: { all: 4 } };
let group3: IGroup = { title: 'Profile Picture', columnSize: { all: 4 } };

let type: IType = {
userId: {
label: getLocalizedText('userId'),
isPrimaryId: true, // Almost every page should have one primary key
typeKey: 'user',

type.password.updateState(); // Refresh the component state
},
},

4) Sidebar Menu & Navigation​

pages.js

Place its menu item.

Be aware of the code block below is simplified and shortened for better understanding.

import React from 'react';
import _ from 'lodash';
import { getLocalizedText } from './common/localizationManager';

const SamplePage = React.lazy(() => import('./views/Routes/SamplePage/SamplePageConfig'));

var PageInfos = {
// -- Addition Beg --
SamplePage: {
name: 'Sample Page Title',
url: `/SamplePage`,
component: SamplePage,
resourceCode: 'SamplePage_Resource_Code',
icon: 'icon-some',
}
// -- Addition End --
}
....

5) Here below is what you're gonna get by almost no-coding but only json-declaration.​
