camelcase

What is camelcase?

The camelcase npm package is used to convert strings to camel case. This means it takes input strings with spaces, hyphens, underscores, or a mix of different delimiters and converts them into a string where the first letter of each word is capitalized except for the first word, and all the words are joined without spaces.

What are camelcase's main functionalities?

String Conversion to Camel Case

Converts a hyphenated string to camel case.

"foo-bar".pipe(camelCase); // 'fooBar'

Handling Multiple Delimiters

Converts a string with multiple delimiters to camel case.

"foo_bar--baz foo".pipe(camelCase); // 'fooBarBazFoo'

Preserving Consecutive Uppercase Characters

Converts a string to camel case while preserving consecutive uppercase characters.

"foo-BAR".pipe(camelCase({ pascalCase: false })); // 'fooBAR'

Converting to Pascal Case

Converts a string to pascal case, which is similar to camel case but with the first letter capitalized.
