Advanced tools
Stringify an object/array like JSON.stringify just without all the double-quotes
The stringify-object npm package is used to stringify an object into a string format that is more readable than JSON.stringify, especially for multi-line strings and functions. It provides options to customize the output, such as indentation, single quotes, and filtering of object properties.
Stringify an object with custom indentation
This feature allows you to convert an object to a string with a specified indentation for better readability. The code sample demonstrates how to use a two-space indentation.
const stringifyObject = require('stringify-object');
const obj = {foo: 'bar', 'arr': [1, 2, 3]};
console.log(stringifyObject(obj, {
indent: ' '
}));
Stringify an object using single quotes
This feature allows you to stringify an object using single quotes instead of double quotes for string values. The code sample shows how to enable this option.
const stringifyObject = require('stringify-object');
const obj = {foo: 'bar'};
console.log(stringifyObject(obj, {
singleQuotes: true
}));
Filter properties during stringification
This feature allows you to filter out properties from the resulting string based on a custom function. The code sample demonstrates excluding the 'baz' property from the stringified output.
const stringifyObject = require('stringify-object');
const obj = {foo: 'bar', baz: 'qux'};
console.log(stringifyObject(obj, {
filter: (obj, prop, value) => prop !== 'baz'
}));
This package offers a way to stringify JSON data in a pretty (indented) yet compact (no unnecessary whitespace) form. It is similar to stringify-object but focuses on compactness and does not handle functions or undefined values.
Developed by Facebook as part of the Jest testing framework, pretty-format allows serialization of JavaScript objects into a string with pretty printing. It supports plugins and can handle React elements, which makes it more versatile than stringify-object for certain use cases.
Flatted is a package that can stringify and parse objects with circular references, which JSON.stringify cannot handle. It is similar to stringify-object in that it provides a way to represent objects as strings, but it is specifically designed to work with circular data structures.
Stringify an object/array like JSON.stringify just without all the double-quotes.
Useful for when you want to get the string representation of an object in a formatted way.
It also handles circular references and lets you specify quote type.
$ npm install --save stringify-object
var obj = {
foo: 'bar',
'arr': [1, 2, 3],
nested: { hello: "world" }
};
var pretty = stringifyObject(obj, {
indent: ' ',
singleQuotes: false
});
console.log(pretty);
/*
{
foo: "bar",
arr: [
1,
2,
3
],
nested: {
hello: "world"
}
}
*/
Circular references will be replaced with "[Circular]"
.
Required
Type: object
, array
Type: string
Default: '\t'
Choose the indentation you prefer.
Type: boolean
Default: true
Set to false to get double-quoted strings.
Type: function
Expected to return a boolean of whether to keep the object.
Type: number
Default: undefined
When set, will inline values up to inlineCharacterLimit
length for the sake
of more terse output.
For example, given the example at the top of the README:
var obj = {
foo: 'bar',
'arr': [1, 2, 3],
nested: { hello: "world" }
};
var pretty = stringifyObject(obj, {
indent: ' ',
singleQuotes: false,
inlineCharacterLimit: 12
});
console.log(pretty);
/*
{
foo: "bar",
arr: [1, 2, 3],
nested: {
hello: "world"
}
}
*/
As you can see, arr
was printed as a one-liner because its string was shorter
than 12 characters.
