util.ts

Overview

The util.ts file provides simple utility functions designed to check specific string values related to types used elsewhere in the application. These functions help determine whether a given type matches predefined categories such as 'folder' or 'knowledgebase'. The purpose of this file is to centralize these common type-checking operations, promoting code reuse and improving readability in parts of the system that deal with content classification or source types.

Functions

isFolderType

export function isFolderType(type: string): boolean

Description:
Checks if the provided string type represents a folder type. This function returns true if the input exactly matches the string 'folder', and false otherwise.

Parameters:

• type (string): The string value to check against the folder type.

Returns:

• boolean: true if type is 'folder', else false.

Usage Example:

import { isFolderType } from './util';

const type1 = 'folder';
console.log(isFolderType(type1)); // Output: true

const type2 = 'document';
console.log(isFolderType(type2)); // Output: false

isKnowledgeBaseType

export function isKnowledgeBaseType(sourceType: string): boolean

Description:
Determines if the provided string sourceType matches the knowledge base type identifier. Returns true if sourceType equals the string 'knowledgebase', else returns false.

Parameters:

• sourceType (string): The string value to verify as a knowledge base type.

Returns:

• boolean: true if sourceType is 'knowledgebase', otherwise false.

Usage Example:

import { isKnowledgeBaseType } from './util';

const source1 = 'knowledgebase';
console.log(isKnowledgeBaseType(source1)); // Output: true

const source2 = 'external';
console.log(isKnowledgeBaseType(source2)); // Output: false

Implementation Details

Both functions use simple strict equality checks (===) to compare input strings to their expected constants. This approach ensures fast and accurate type matching without additional overhead. No complex algorithms or external dependencies are involved, making these utilities lightweight and efficient.

Interaction with Other Parts of the System

This utility file is likely imported by various modules or components that handle content organization, data source management, or type-based processing within the application. For example:

• A file or folder management module may use isFolderType to distinguish folders from other file types.

• A data ingestion or syncing module might use isKnowledgeBaseType to identify knowledge base sources among multiple source types.

Centralizing these type checks in util.ts avoids scattering magic strings throughout the codebase, reducing errors and simplifying future updates if type identifiers change.

This flowchart illustrates the two main functions, each taking a string parameter and returning a boolean based on a strict equality check against a fixed string.

Summary

• util.ts contains two boolean utility functions to verify if a given string matches the type 'folder' or 'knowledgebase'.

• It provides a centralized and reusable way to handle type checks in the application.

• The implementations are straightforward, using strict equality checks.

• Other parts of the system likely depend on these utilities for classification logic related to folders and knowledge base sources.
