How to Use Uuid in TypeScript Nodejs App
This tutorial provides a deep dive with guidelines about the npm package uuid
in TypeScript Nodejs App used with the developers’ best and most popular methods.
This will guide us about the usage of uuid
in the TypeScript Nodejs App with coding and give the main reason for installing the package into the project.
First, let’s see the npm package uuid
and its use among the developer community.
Purpose and Usage of UUID
UUID, which stands for Universal Unique Identifier, is a unique value that is practically useful in jobs like the migration of data on the databases with other uses like identifying information that needs to be unique within a network or system.
The uniqueness and low probability of repeated UUID make them useful as identifiers for physical hardware within an organization and associative keys in databases.
UUID is an excellent way to hide sequential database IDs. The npm
package manager offers a package called uuid
to use in the project for performing the above tasks in the app.
Now let’s set up the TypeScript Nodejs project with the uuid
package.
Install and Implement the uuid
Package in TypeScript Nodejs
First, enter the following command to initialize the package.json
in the project.
npm i -y
Output:
After initializing the package.json
in the project, enter the following command for setting up TypeScript in the project:
npm i typescript --save-dev
Then, add the following lines to the tsconfig.json
file:
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"strict": true,
"outDir": "dist",
"sourceMap": true
}
}
After configuring TypeScript to the project, add the uuid
package to the project by running the following command:
npm install uuid
These steps will set the project up with the uuid
package dependency.
To use the uuid
in the TypeScript project, import the v4
constant in the file as UUID from which we can produce the Universal Unique Identifier.
import { v4 as uuid } from 'uuid';
const id: string = uuid();
console.log(id)
Output:
