## Strongly-typed string functions for all!



![A demonstration of string-ts](https://github.com/gustavoguichard/string-ts/assets/566971/0aa5603f-871d-4eb7-8ace-6a73466cec4d)



## 😬 The problem



When you are working with literal strings, the string manipulation functions only work at the runtime level and the types don't follow those transformations.

You end up losing type information and possibly having to cast the result.



```ts

const str = 'hello-world'

const result = str.replace('-', ' ') // you should use: as 'hello world'

//    ^? string

```



## 🤓 The solution



This library aims to solve this problem by providing a set of common functions that work with literal strings at both type and runtime level.



```ts

import { replace } from 'string-ts'



const str = 'hello-world'

const result = replace(str, '-', ' ')

//    ^ 'hello world'

```



## 🔍 Why this matters



TypeScript yields the best static analysis when types are highly specific.

Literals are more specific than type `string`.

This library preserves literals (and unions of literals) after transformations, unlike most existing utility libraries (and built-in string methods.)



[I still don't get the purpose of this library 🤔](#%EF%B8%8F-interview)



### In-depth example



In the below example, I want to get a strongly-typed, camel-case version of `process.env`.

One flow results in a loose type, and the other results in a more precise type.

This example should illustrate the highly-specific and flexible nature of `string-ts`.



```ts

import { deepCamelKeys } from 'string-ts'

import { camelCase, mapKeys } from 'lodash-es'

import z from 'zod'



const EnvSchema = z.object({

  NODE_ENV: z.string(),

})



function getEnvLoose() {

  const rawEnv = EnvSchema.parse(process.env)

  const env = mapKeys(rawEnv, (_v, k) => camelCase(k))

  //    ^? Dictionary



  // `Dictionary` is too loose

  // TypeScript is okay with this, 'abc' is expected to be of type `string`

  // This will have unexpected behavior at runtime

  console.log(env.abc)

}



function getEnvPrecise() {

  const rawEnv = EnvSchema.parse(process.env)

  const env = deepCamelKeys(rawEnv)

  //    ^? { nodeEnv: string }



  // Error: Property 'abc' does not exist on type '{ nodeEnv: string; }'

  // Our type is more specific, so TypeScript catches this error.

  // This mistake will be caught at compile time

  console.log(env.abc)

}



function main() {

  getEnvLoose()

  getEnvPrecise()

}



main()

```



## 📦 Installation



```bash

npm install string-ts

```



## 🌳 Tree shaking



`string-ts` has been designed with tree shaking in mind.

We have tested it with build tools like Webpack, Vite, Rollup, etc.



## 👌 Supported TypeScript versions



`string-ts` currently only works on TypeScript v5+.



It also only work with common ASCII characters characters. We don't plan to support international characters or emojis.

## Type utilities



All the functions presented in this API have associated type counterparts.



```ts

import type * as St from 'string-ts'

```



### Native TS type utilities



```ts

Capitalize<'hello world'> // 'Hello world'

Lowercase<'HELLO WORLD'> // 'hello world'

Uppercase<'hello world'> // 'HELLO WORLD'

```



### General type utilities from this library



```ts

St.CharAt<'hello world', 6> // 'w'

St.Concat<['a', 'bc', 'def']> // 'abcdef'

St.EndsWith<'abc', 'c'> // true

St.Includes<'abcde', 'bcd'> // true

St.Join<['hello', 'world'], '-'> // 'hello-world'

St.Length<'hello'> // 5

St.PadEnd<'hello', 10, '='> // 'hello====='

St.PadStart<'hello', 10, '='> // '=====hello'

St.Repeat<'abc', 3> // 'abcabcabc'

St.Replace<'hello-world', 'l', '1'> // 'he1lo-world'

St.ReplaceAll<'hello-world', 'l', '1'> // 'he11o-wor1d'

St.Reverse<'Hello World!'> // '!dlroW olleH'

St.Slice<'hello-world', -5> // 'world'

St.Split<'hello-world', '-'> // ['hello', 'world']

St.Trim<' hello world '> // 'hello world'

St.StartsWith<'abc', 'a'> // true

St.TrimEnd<' hello world '> // ' hello world'

St.TrimStart<' hello world '> // 'hello world '

St.Truncate<'hello world', 9, '[...]'> // 'hello[...]

St.Words<'hello-world'> // ['hello', 'world']

```



### Casing type utilities



#### Core



```ts

St.CamelCase<'hello-world'> // 'helloWorld'

St.ConstantCase<'helloWorld'> // 'HELLO_WORLD'

St.DelimiterCase<'hello world', '.'> // 'hello.world'

St.KebabCase<'helloWorld'> // 'hello-world'

St.PascalCase<'hello-world'> // 'HelloWorld'

St.SnakeCase<'helloWorld'> // 'hello_world'

St.TitleCase<'helloWorld'> // 'Hello World'

```



##### Missing types



_Note that we do not include `UpperCase` and `LowerCase` types. These would be too close to the existing TS types `Uppercase` and `Lowercase`._



One could create either by doing like so:



```ts

type LowerCase = Lowercase>

type UpperCase = Uppercase>

// or

type LowerCase = ReturnType>

type UpperCase = ReturnType>

```



#### Shallow object key transformation



```ts

St.CamelKeys<{

  'hello-world': { 'foo-bar': 'baz' }

}> // { helloWorld: { 'foo-bar': 'baz' } }

St.ConstantKeys<{

  helloWorld: { fooBar: 'baz' }

}> // { 'HELLO_WORLD': { fooBar: 'baz' } }

St.DelimiterKeys<{ 'hello-world': { 'foo-bar': 'baz' } }, '.'>

// { 'hello.world': { 'foo-bar': 'baz' } }

St.KebabKeys<{

  helloWorld: { fooBar: 'baz' }

}> // { 'hello-world': { fooBar: 'baz' } }

St.PascalKeys<{

  'hello-world': { 'foo-bar': 'baz' }

}> // { HelloWorld: { 'foo-bar': 'baz' } }

St.SnakeKeys<{

  helloWorld: { fooBar: 'baz' }

}> // { 'hello_world': { fooBar: 'baz' } }

```



#### Deep object key transformation



```ts

St.DeepCamelKeys<{

  'hello-world': { 'foo-bar': 'baz' }

}> // { helloWorld: { fooBar: 'baz' } }

St.DeepConstantKeys<{

  helloWorld: { fooBar: 'baz' }

}> // { 'HELLO_WORLD': { 'FOO_BAR': 'baz' } }

St.DeepDelimiterKeys<

  {

    'hello-world': { 'foo-bar': 'baz' }

  },

  '.'

> // { 'hello.world': { 'foo.bar': 'baz' } }

St.DeepKebabKeys<{

  helloWorld: { fooBar: 'baz' }

}> // { 'hello-world': { 'foo-bar': 'baz' } }

St.DeepPascalKeys<{

  'hello-world': { 'foo-bar': 'baz' }

}> // { HelloWorld: { FooBar: 'baz' } }

St.DeepSnakeKeys<{

  helloWorld: { fooBar: 'baz' }

}> // { 'hello_world': { 'foo_bar': 'baz' } }

```



### Other exported type utilities



```ts

St.IsDigit<'a'> // false

St.IsDigit<'1'> // true

St.IsLetter<'a'> // true

St.IsLetter<'1'> // false

St.IsLower<'a'> // true

St.IsLower<'A'> // false

St.IsUpper<'a'> // false

St.IsUpper<'A'> // true

St.IsSeparator<' '> // true

St.IsSeparator<'-'> // true

St.IsSeparator<'a'> // false

St.IsSpecial<'a'> // false

St.IsSpecial<'!'> // true

St.IsSpecial<' '> // false

```



## Runtime-only utilities



### deepTransformKeys



This function recursively converts the keys of an object to a custom format, but only at runtime level.



```ts

import { deepTransformKeys, toUpperCase } from 'string-ts'



const data = { helloWorld: 'baz' } as const



type MyType = { [K in keyof T as Uppercase]: T[K] }

const result = deepTransformKeys(data, toUpperCase) as MyType

//    ^ { 'HELLOWORLD': 'baz' }

```
