interface InspectOptions

Usage in Deno

import { type InspectOptions } from "node:util";

Properties

optional
showHidden: boolean | undefined

If true, object's non-enumerable symbols and properties are included in the formatted result. WeakMap and WeakSet entries are also included as well as user defined prototype properties (excluding method properties).

optional
depth:
number
| null
| undefined

Specifies the number of times to recurse while formatting object. This is useful for inspecting large objects. To recurse up to the maximum call stack size pass Infinity or null.

optional
colors: boolean | undefined

If true, the output is styled with ANSI color codes. Colors are customizable.

optional
customInspect: boolean | undefined

If false, [util.inspect.custom](depth, opts, inspect) functions are not invoked.

optional
showProxy: boolean | undefined

If true, Proxy inspection includes the target and handler objects.

optional
maxArrayLength:
number
| null
| undefined

Specifies the maximum number of Array, TypedArray, WeakMap, and WeakSet elements to include when formatting. Set to null or Infinity to show all elements. Set to 0 or negative to show no elements.

optional
maxStringLength:
number
| null
| undefined

Specifies the maximum number of characters to include when formatting. Set to null or Infinity to show all elements. Set to 0 or negative to show no characters.

optional
breakLength: number | undefined

The length at which input values are split across multiple lines. Set to Infinity to format the input as a single line (in combination with compact set to true or any number >= 1).

optional
compact:
boolean
| number
| undefined

Setting this to false causes each object key to be displayed on a new line. It will also add new lines to text that is longer than breakLength. If set to a number, the most n inner elements are united on a single line as long as all properties fit into breakLength. Short array elements are also grouped together. Note that no text will be reduced below 16 characters, no matter the breakLength size. For more information, see the example below.

optional
sorted:
boolean
| ((
a: string,
b: string,
) => number)

| undefined

If set to true or a function, all properties of an object, and Set and Map entries are sorted in the resulting string. If set to true the default sort is used. If set to a function, it is used as a compare function.

optional
getters:
"get"
| "set"
| boolean
| undefined

If set to true, getters are going to be inspected as well. If set to 'get' only getters without setter are going to be inspected. If set to 'set' only getters having a corresponding setter are going to be inspected. This might cause side effects depending on the getter function.

optional
numericSeparator: boolean | undefined

If set to true, an underscore is used to separate every three digits in all bigints and numbers.
