Textcases

Validate text case and convert strings from a case to another. Useful to validate/enforce naming conventions, convert names into code, and more.

Supported formats: | Case | Validation | Conversion | Output | |------|------------|------------|--------| | Camel case | isValidCamelCase | toCamelCase | helloWorld | | Cobol case | isValidCobolCase | toCobolCase | HELLO-WORLD | | Flat case | isValidFlatCase | toFlatCase | helloworld | | Kebab case | isValidKebabCase | toKebabCase | hello-world | | Macro case | isValidMacroCase | toMacroCase | HELLO_WORLD | | Pascal case | isValidPascalCase | toPascalCase | HelloWorld | | Sentence case | isValidSentenceCase | toSentenceCase | Hello world | | Snake case | isValidSnakeCase | toSnakeCase | hello_world | | Title case | isValidTitleCase | toTitleCase | Hello World | | Train case | isValidTrainCase | toTrainCase | Hello-World | | Upper flat case | isValidUpperFlatCase | toUpperFlatCase | HELLOWORLD |

Installation

npm install textcases

Usage

Case validation

Use any of the shorthand validation function, for example:

import { isValidCamelCase } from 'textcases';

isValidCamelCase('helloWorld'); // true
isValidCamelCase('HelloWorld'); // false

Or use the generic validate function, for example:

import { validate, Case } from 'textcases';

validate('helloWorld', Case.CAMEL_CASE); // true
validate('HelloWorld', Case.CAMEL_CASE); // false

Case conversion

Use any of the shorthand conversion function, for example:

import { toCamelCase } from 'textcases';

toCamelCase('hello world'); // helloWorld

Or use the generic convert function:

import { convert, Case } from 'textcases';

convert('hello world', Case.CAMEL_CASE); // helloWorld

If you know the source case, you can add it as the second parameter of either shorthands or generic functions:

import { toCamelCase, convert, Case } from 'textcases';

toCamelCase('HelloWorld', Case.PASCAL_CASE);
convert('HelloWorld', Case.CAMEL_CASE, Case.PASCAL_CASE);

Note that if you pass the source case, the source string will be validated against this case and an error can be thrown if it doesn't match.
