ReactiveSearch provides React UI components for Elasticsearch. This document explains the different kinds of components offered by the library and walks throughs scenarios of when to use which component.
Components are divided into four broad categories:
List componentsrepresent all kinds of list related UI components which typically create a term query.
Range componentsrepresent all kinds of numbers and dates related UI components which typically create a range based query.
Search componentsrepresent searchbar UIs, which typically apply search on full-text data.
Result componentsare components for displaying results (aka hits) from queries created by other components.
Besides these four specific categories, we also have
Base components that are useful primitives and components that don’t belong to any of the above categories.
1. List Components
List is one of the most used data-driven UI displays and hence naturally, we offer a variety of ways to use this UI style.
String or Text Datatype
The following are all the possible UI components for a
String datatype field in your appbase.io app. These apply a term or terms database query on the selected item(s).
The components can also be used with
Numeric datatype fields.
SingleDropdownList displays a dropdown list UI where only one item can be selected at a time. It is similar to SingleList but is presented in a dropdown format to save space.
MultiDropdownList displays a dropdown list UI where multiple items can be selected at a time. It is similar to MultiList.
When to use dropdown lists
Dropdown lists take up less space. If you have many filters to display or a smaller display area (like on phones), it is better to use dropdown lists.
2. Range Components
The following are all the possible UI components for a numeric datatype field in your appbase.io app. These apply a range database query on the selected item(s).
SingleDropdownRange displays a dropdown list UI where only one item can be selected at a time. Each item in this dropdown list represents a range, specified in the data prop of the component.
MultiDropdownRange displays a dropdown list UI where only multiple items can be selected at a time. Each item in this dropdown list represents a range, specified in the data prop of the component.
DatePicker and DateRange
3. Search Components
The following are UI components that represent searchbar UIs. The datatype for the
dataField in these components should be a
Keyword, along with custom analyzer (like ngrams) based mappings defined in sub-fields.
DataSearch displays a search input box. It supports autosuggestions, highlighting of results and querying against more than one fields via props.
If you are looking to apply a query on a user input, DataSearch is preferable over TextField.
4. Result Components
Result components are used for displaying the results (aka hits).
How do result components fetch results by combining queries from multiple components?
They do this via react prop, which allows each component to specify their dependent components using a DSL that mirrors Elasticsearch’s compound query DSL for bool clause.
ReactiveList displays the results in a configurable list layout.
5. Base Components
TextField displays a text input field. It applies a match database query on the entered text.
ReactiveComponent is a wrapper component that allows you to connect custom component(s) (passed as children) with the Reactivesearch ecosystem, e.g. if we are building an e-commerce store where we have a react component called
ColorPicker which renders the
colors passed to it as tiles, allowing us to filter the products by their colors.
