string-injector
Little helper to replace placeholders by mapped values into a string
Ecosystem
This package has been developped under node v17.9.0 (but probably works on earlier versions).
Installation
npm install --save @xenoarea/stringjector
Usage
import injectValues from '@xenoarea/string-injector'
const valuesMap = {
name: 'Xeno',
info: {
gender: 'male',
age: 31,
hobbies: [
'programmation',
'pixel art'
]
}
}
const template = 'I am {{name}}, a {{info.gender}} of {{info.age}} years old and I like doing {{info.hobbies.0}} and {{info.hobbies.$}}.'
const output = injectValues(template, valuesMap)
console.log(output) //output: I am Xeno, a male of 31 years old and I like doing programmation and pixel art.
Syntax
In the example snippet above you can notice the usage of placeholders starging by {{ and ending by }}.
Those placeholders are key path of where to find the remplacement value in the given values map object.
Note also the usage of the $ character in the key path to signify we want to get the last element of
an array.
