Object Trim

Trims objects recursively by applying various rules:

- total maximum of members (counting all array items and object keys, recursively)
- maximum number of items in each array
- maximum number of keys in each object
- maximum string length

Useful to create "previews" of big objects that don't destroy your database.

Highlights

- 🔥 Zero dependencies
- 🗜 Tidy and compact
- 💻 Works in browser

Usage

``ts
import { objectTrim } from '@nodescript/object-trim';

const obj = {
foo: {
a: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
b: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
c: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
d: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
e: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
f: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
g: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
},
bar: {
a: 'Loooooooooooong string',
b: 'Loooooooooooong string',
c: 'Loooooooooooong string',
d: 'Loooooooooooong string',
e: 'Loooooooooooong string',
f: 'Loooooooooooong string',
g: 'Loooooooooooong string',
h: 'Loooooooooooong string',
i: 'Loooooooooooong string',
j: 'Loooooooooooong string',
}
};

const trimmed = objectTrim(obj, {
maxArrayLength: 2,
maxObjectFields: 4,
maxStringLength: 4,
maxTotalFields: 16,
});
`

Result:

`js
{
foo: {
a: [0, 1],
b: [0, 1],
c: [0, 1],
d: [0, 1],
},
bar: {
a: 'Loo…',
b: 'Loo…',
},
}
`

Or with addPlaceholders: true option:

`js
{
foo: {
a: [ 0, 1, '8 more items' ],
b: [ 0, 1, '8 more items' ],
c: [ 0, 1, '8 more items' ],
d: [ 0, 1, '8 more items' ],
'...': '3 more key(s)'
},
bar: {
a: 'Loo…',
b: 'Loo…',
'...': '8 more key(s)',
}
}
