**Task:** "Parse and build URL query strings."

```bash
|

npm install query-string

|
```
|
|
|
|
```js
|
|
import qs from "query-string";
|
|
|
|
// Parse
|
|
const params = qs.parse(location.search);
|
|
// → { page: "2", sort: "name", tags: ["js", "css"] }
|
|
|
|
// Build
|
|
const url = qs.stringify({ page: 2, sort: "name", tags: ["js", "css"] });
|
|
// → "page=2&sort=name&tags=js&tags=css"
|
|
```
|
|
|
|
## With Ponytail
|
|
|
|
```js
|
|
// ponytail: URLSearchParams does this
|
|
const params = new URLSearchParams(location.search);
|
|
|
|
// Read
|
|
params.get("page"); // "2"
|
|
params.getAll("tags"); // ["js", "css"]
|
|
|
|
// Build
|
|
const out = new URLSearchParams({ page: 2, sort: "name" });
|
|
out.append("tags", "js");
|
|
out.append("tags", "css");
|
|
out.toString(); // "page=2&sort=name&tags=js&tags=css"
|
|
```

**1 dependency → 0 dependencies.** `URLSearchParams` is in every browser and in Node.js since v10. It handles encoding, repeated keys, and iteration. The package was a polyfill for an API that has shipped everywhere for years.
