7月 2, 2025
Isomorphic SoftwareのSmartClientは、データの関係を自動的に表示、編集、更新するためのノーコードソリューションを提供

SmartClient is a comprehensive JavaScript component suite compatible with React, Vue, Angular, and more, that allows you to create large-scale, high-productivity web applications. It provides a comprehensive set of tools for developers, including advanced UI components, robust data management capabilities, and integration with modern backend technologies. Key features include dynamic data fetching, customizable grids, and a responsive interface for a wide range of devices. SmartClient enables developers to create applications with optimized performance, scalability, and a superior user experience. Ideal for enterprise-grade use cases, such as financial analytics, inventory management, and real-time reporting, SmartClient empowers organizations to deliver feature-rich applications that handle complex data requirements with ease.

Relations connect objects to each other and are used in databases and systems that are object-oriented. SmartClient lets you declare these relations in your data source using Relation Fields, providing a full access to related data without the need to write additional code. With two new user interface (UI) components for editing related records and the Relation Fields feature, it is now easier to manage many-to-many relationships. "MultiPickerItem" is a compact control used for inline form editing where the selected values appear inline and a pop-up displays checkboxes to enable users to select from a related data source. The Shuttle Interface can be embedded in any layout, including forms and modals, and provides a visual dual-panel interface for handling multi-item associations. These features simplify the management of relational data, offering users a declarative, scalable, and user-friendly approach.

SmartClient is licensed per developer and is available as both perpetual and subscription licenses. Product updates and technical support is also available. See our SmartClient licensing page for full details.

ガントチャートを使用してタイムクリティカルなタスクを調整

7月 1, 2025
ガントチャートは、タスクを経時的にマッピングし、チームがスケジュールを管理し、競合を特定し、複雑なプロジェクトタイムライン全体の可視性を維持可能

A Gantt chart is a visual project management tool that displays tasks or activities along a timeline, allowing teams to see the start and end dates, duration, and dependencies of each task within a project. Typically represented as horizontal bars across a calendar-based axis, Gantt charts provide a clear overview of project progress and help identify potential bottlenecks or scheduling conflicts. Gantt charts improve planning, scheduling, team coordination, and stakeholder transparency by clearly organizing tasks and timelines. They are especially valuable in complex projects, offering both macro and micro views to support informed decision-making and efficient execution.

Several JavaScript chart controls provide Gantt charts including:

  • AnyGantt JS by AnyChart allows you to build feature-rich Gantt charts for project tracking, including task grouping, critical paths, and interactive controls.
  • FusionCharts Suite XT lets you create interactive Gantt charts that visualize task timelines, dependencies, and progress with rich, customizable styling.
  • Syncfusion JavaScript Chart (part of Syncfusion Essential Studio Enterprise) provides dynamic Gantt chart support with drag-and-drop scheduling and real-time task updates.
  • DevExtreme Chart (part of DevExtreme Complete by DevExpress) facilitates Gantt chart rendering, enabling task planning with milestone tracking and zoomable time scales.

スクロール時にグリッド行を動的にレンダリング

6月 30, 2025
仮想スクロールと無限スクロールを使用して、表示されるコンテンツを動的にレンダリングし、JavaScriptアプリケーションのデータグリッドの性能が向上

The ability to load items in a data grid as you scroll is a technique where content is rendered or fetched dynamically based on the user’s scroll position. Its purpose is to improve performance, and ultimately the user experience, when dealing with large datasets. This includes virtual scrolling, where the grid only renders rows that are currently visible in the viewport and reuses those same DOM elements as the user scrolls, and infinite scrolling (also known as endless scrolling), where additional data is loaded from a remote source in response to reaching the end of the currently displayed dataset. By minimizing the amount of data rendered or retrieved at any one time, this approach significantly reduces initial load times, improves responsiveness, and allows applications to scale efficiently.

Several JavaScript grid components allow you to load items as the user scrolls, including:

  • DevExtreme HTML5 JavaScript Data Grid (part of DevExtreme by DevExpress) supports both virtual and infinite scrolling to optimize data loading performance.
  • KendoReact Data Grid (part of KendoReact by Telerik) offers customizable column/row virtualization and virtual scrolling, dynamically requesting data as needed.
  • Sencha Ext JS Grid (part of Sencha Ext JS) implements infinite scrolling through a virtualized system that loads data on demand without traditional pagination.
  • Syncfusion DataGrid for JavaScript (part of Syncfusion Essential Studio Enterprise) allows both virtualization and infinite scrolling for responsive grid rendering.

Vue.jsアプリケーションでチャートをアニメーション化

6月 24, 2025
アニメーションを使用すると、開発者はデータの理解と解釈を容易にする、より魅力的なグラフを作成可能

Animation in charts is a feature used in data visualization to visually transition between different data states or configurations. This technique helps communicate changes in data over time or between user interactions in a smooth, progressive manner. Rather than instantly switching from one state to another, animation introduces motion that can guide users’ attention, reinforce patterns, and reduce confusion. It is particularly useful in interactive dashboards and real-time analytics, where users benefit from a clearer understanding of what has changed and how.

Several Vue.js charting components support the use of animations, including:

  • DevExtreme Chart (part of DevExtreme by DevExpress) offers high-performance Vue components for data visualization that integrate configurable animation options.
  • Wijmo FlexChart and FinancialChart (part of Wijmo by MESCIUS) incorporates various animation modes and timing controls for visualizing data in web applications.
  • Highcharts Core by Highsoft is a JavaScript charting library that can equip Vue.js apps with advanced animation functionality for highlighting data and aiding data interpretation.
  • Kendo UI for Vue Chart (part of Kendo UI by Telerik) features built-in animations that respond to data changes in real-time, creating engaging transitions by default.
