object-grep

object-grep

A javascript tool for searching inside objects inspired by linux grep

installation

npm i object-grep

or

yarn add object-grep

arguments

targetObject: [object | array | function | string] - a target object where all keys and property contents will be recursively checked for matching searchExpr

searchExpr: [string | regexp] - expression for checking for compliance

depth limit?: [number] - the number of levels to check. objectGrep works synchronously, which can cause the browser to freeze if the object being checked is very large. The default value is 100

usage

const obj = {
    foo: {
        bar: {
            baz: {
                foo: {
                    bar: {
                        baz: 'zab'
                    }
                }
            }    
        }
    },
    oof: {
        rab: {
            zab: ['foo', 'bar', 'baz', 'zab', 'rab', 'oof']
        }
    }
}

objectGrep(obj, 'baz') // => {keys: ['foo.bar.baz', 'foo.bar.baz.foo.bar.baz'], values: ['oof.rab.zab.2']}

// or regexp

objectGrep(obj, /b.z/) // => {keys: ['foo.bar.baz', 'foo.bar.baz.foo.bar.baz'], values: ['oof.rab.zab.2']}

// or with depth limit

objectGrep(obj, /b.z/, 4) // => {keys: ['foo.bar.baz'], values: ['oof.rab.zab.2']}

inject

It can be added to the object prototype

objectGrep.inject()

const obj = { a: { b : { c: 'd' } } }

obj.grep('b') // => {keys: ['a.b']}

chrome extension

You can also install a browser extension and use object-grep on any site without any extra effort
