npm install @polymer-co/ropeRope JS extends the inbuilt JavaScript string type with additional helper methods. It's focus is to be simple and to not require wrapper classes - all you need to do is require or import it, then start using! See src/rope.ts for available methods.
It includes super useful helper methods; from inserting strings, capitalizing, random sampling, and more! Rope JS also provides utilities for case conversion (ie, camel case to pascal), allowing you to convert from all the well-known casings to any other. Case conversions include:
| Case | Example | Lossy? |
|---|---|---|
| camel | helloWorld |
No |
| camelSnake | hello_World |
No |
| cobol | HELLO-WORLD |
No |
| flat | helloworld |
Yes |
| kebab | hello-world |
No |
| macro | HELLO_WORLD |
No |
| pascal | HelloWorld |
No |
| sarcastic | hElLo wOrLd |
No |
| sentence | hello, world |
No |
| snake | hello_world |
No |
| train | Hello-World |
No |
| upperFlat | HELLOWORLD |
Yes |
'Lossy' implies that word seperation will be lost when converting to this case. For example, converting from camel to flat will result in 'camelCase' being converted to 'camelcase' - the flat case output cannot be converted back into camelCase, as word seperation has not been preseved.
TypeScript types declaration files are included by default.
