About inserturlparams

Insert dynamic data in url path/search params. Works client side or in NodeJS. Really
useful for big web projects where you store large numbers of long urls.

- TypeScript supported :3

#### How it works
- It replaces any part of a url that starts with /:. i.e. /api/v1/:param/hello
with a value from an array or object.
- insertUrlParams(urlString, pathParams) => full-url-string.

#### Installation
- npm i -s inserturlparams

#### Important
- For path-params, non-primitive values will throw errors, empty strings will be
skipped, but null and undefined will still be included.
- For search-params, arrays and primitives are allowed: arrays can only contain
primitives and will be join by ,. Empty strings/arrays and undefined will be
skipped but null will still be included.

#### Sample code:
``typescript
import insertUrlParams, {
TParamObj,
TParam,
TSearchParams,
} from '../';


// Example 1: Object keys must match the param names in the url.
const data1: TParamObj = {
id: 5,
msg: 'hello',
really: true,
something: undefined,
random: null,
};
const url1 = '/api/v1/:id/cheese/:msg/is-good/:really/dog/cow/:something/:random';
const resp1 = insertUrlParams(url1, data1);
console.log(resp1); // "/api/v1/5/cheese/hello/is-good/true/dog/cow/undefined/null"


// Example 2: NOTE The array must be in the order that you intend to replace them
// with in the url and the length of the array must match the number of params.
const data2: TParam[] = [5, 'hello', true, undefined, null];
const url2 = '/api/v1/:id/cheese/:msg/is-good/:really/dog/cow/:something/:random';
const resp2 = insertUrlParams(url2, data2);
console.log(resp2); // "/api/v1/5/cheese/hello/is-good/true/dog/cow/undefined/null"


// Example 3: You can use a single primtive.
const resp3 = insertUrlParams('/api/v1/:id/cheese', 5);
console.log(resp3); // "/api/v1/5/cheese";

#### Note from the author
- This is a simple library but a long function that I needed to use in the front-end
(React) and the back-end (ExpressJS). Plus I hadn't written a client side library yet
so this gave me some practice with rollup.js. In my front-end I had a large Routes.ts file
and for readability I wanted to store the routes there the same as how they appeared
in express, that is with /:` inside the url. This required me to format the url before
each api call though so I wrote this function to do just that.

Happy web-deving :)
