## Install
This package is [pure ESM](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c). If you're not ready yet, install an older version of this program, 6.9.0 (`npm i json-comb-core@6.9.0`).
```bash
npm i json-comb-core
```
## Quick Take
```js
import { strict as assert } from "assert";
import {
getKeysetSync,
getKeyset,
enforceKeyset,
enforceKeysetSync,
sortAllObjectsSync,
noNewKeysSync,
findUnusedSync,
} from "json-comb-core";
// STEP #1
// =======
// calculate the schema - superset of all possible keys used across
// all JSON files
const schema = getKeysetSync([
{
// <- object #1
a: "a",
b: "c",
c: {
d: "d",
e: "e",
},
},
{
// <- object #2
a: "a",
},
{
// <- object #3
c: {
f: "f",
},
},
]);
assert.deepEqual(schema, {
a: false,
b: false,
c: {
d: false,
e: false,
f: false,
},
});
// STEP #2
// =======
// now we can normalise the object #2 for example:
assert.deepEqual(
enforceKeysetSync(
{
// <- object #2
a: "a",
},
schema,
),
{
a: "a",
b: false,
c: {
d: false,
e: false,
f: false,
},
},
);
```
