Searchables

npm i @zheeno/searchables

This module allows to you to perform deep search on an array of objects for a keyword matching any entry with an indexed property.

Usage

Step 1 - Import the package into your project:

const { Searchables } = require("@zheeno/searchables");

Step 2 - Create an instance of Searchable and pass the array to be searched as the only parameter:

const data = [{...}];
const search = new Searchables(data);

Step 3 - Configure Searchable indexes:

Indexes can be configured by calling the addIndex() method. It takes in a single parameter which can be of type String or Array[String]

search.addIndex(["index_1", "index_2", ..., "index_n"]);

Step 4 - Invoke the find() method :

The find method takes in an argument of type String and returns a promise which resolves an array of matching results

search
  .find("some value") // accepts 
  .then((res) => {
    console.log("Found =>", res);
  })
  .catch((error) => console.log("Error =>", error.message));

Example 1:

This is a basic example showing a search performed on the indexes on nodes with the lowest depth in the object tree.

const { Searchables } = require("@zheeno/searchables");

const data = [
  {
    name: "Efezino",
    age: 28
  },
  {
    name: "Adeyemi",
    age: 30
  },
  {
    name: "Jeffery",
    age: 22
  },
  {
    name: "Charles",
    age: 18
  },
  {
    name: "Solomon",
    age: 30
  }
];
const search = new Searchables(data);
search.addIndex(["name", "age"]);

search
  .find("jack 30") // accepts a string seprated by whitespaces or special characters 
  .then((res) => {
    console.log("Found =>", res);
  })
  .catch((error) => console.log("Error =>", error.message));

Example 2:

This example shows how to search indexes of an object tree whose node is located at depth N.

const { Searchables } = require("@zheeno/searchables");

const data = [
  {
    name: "Efezino",
    age: 28,
    class: {
      name: "Emerald",
      level: {
        id: "wDex87sm0",
        category:{
          name: "Secondary"
        }
      }
    }
  },
  {
    name: "Adeyemi",
    age: 30,
    class: {
      name: "Pearl",
      level: {
        id: "mM2F0jHah",
        category:{
          name: "Primary"
        }
      }
    }
  },
  {
    name: "Jeffery",
    age: 22,
    class: {
      name: "Silver",
      level: {
        id: "I50SeEDem",
        category:{
          name: "Secondary"
        }
      }
    }
  },
  {
    name: "Charles",
    age: 18,
    class: {
      name: "Gold",
      level: {
        id: "cS34mMab5",
        category:{
          name: "Primary",
        }
      }
    }
  },
  {
    name: "Solomon",
    age: 30,
    class: {
      name: "Gold",
      level: {
        id: "xBjdE332m",
        category:{
          name: "Primary"
        }
      }
    }
  }
];
const search = new Searchables(data);
search.addIndex(["class.name", "class.level.id", "class.level.category.name"]);

search
  .find("xBjdE332m Silver") // accepts a string seprated by whitespaces or special characters 
  .then((res) => {
    console.log("Found =>", res);
  })
  .catch((error) => console.log("Error =>", error.message));
