![]() ![]() The password generation will be random.Īdd the following to the helper file. The helper file will consist of all functions that will be used to create the passwords.Ī user will have the option to create passwords with a combination of uppercase letters, lowercase letters, numbers, and special characters. Inside the utils folder, create a file called Helper.js. The app should look like the image below. Open the App component and replace its content with the following. The main component is then added to App.js. The header and display components need to be added to Main.js. The display component will consist of a password display and buttons to copy and reload a new password.Īdd a function to Display.js. The header component contains the text to be displayed on the page. In the components folder, add the following files and folders.Ĭopy and paste the code below into the Header.js file.Ĭreate strong passwords with Password GeneratorĪdd CSS style Header.css file. The components folder contains all the required components. Ĭreate two new folders called components and utils inside the src directory. import 'bootstrap/dist/css/' Īdd the following to the head section of index.html inside the public folder. Open a terminal inside the project and run: yarn add bootstrapĪdd the following to index.css. You can open the project with an IDE of your choice. This is the directory that contains the entry component ( App.js) and where other components will be created. npx create-react-app password-generatorĬreate-react-app creates a src directory. Open a command prompt or terminal, navigate to the directory where you want to add your project, and type the following. I’ll assume you have Node.js installed on your computer. We’ll create the following components.īefore we start, we need to create a React application. It’ll also have an indicator to help gauge the strength of the user’s chosen password.Īs part of the tutorial, you’ll learn how to create reusable components in React. The app will enable users to create strong passwords with various combinations of characters, including uppercase and lowercase letters, symbols, and numbers. In this guide, we’ll walk through how to create a password generator app with React. Build a password generator app in React with reusable components To help me keep track of this series of posts I’ve created a list on Medium: Dev Advent Calendar - The advent diary of an amateur programmer.Uzochukwu Eddie Odozi Follow Web and mobile app developer. So I add a characters variable and start typing random letters in the password:įinally I create a helper function to mix the array: But passing all available characters as an argument. By combining these three pieces I can be sure that I have a character for each set selected in the password:įor the remaining characters I reuse the randomChar() function. I need to decide which character sets to use. It remains to understand how to scroll through the various properties of an object. I create a helper function to pick a random letter from a string. In this way I can, in the future, increase or decrease the available properties: To manage the character sets, however, I use a separate object. Then I’ll mix the array with all the characters and turn it into a string with the () method. I think a good method would be to create each character independently and save it into an array. To do this I had to decide how the password will be generated. The next step is to make sure there is at least one character of each type selected. I use the same variable to verify that the required length is correct: Just check its length to understand if there are properties or not: This method returns an array with the names of the various properties of an object. To do this I use the Object.keys() method. I need to verify that the options argument is not empty. There must be a character for each option property. The generatePassword function returns a string of random characters. ![]() ![]() Likewise, it is not necessary to pass all properties to the function. To simplify, problem tests always consider every property in the options object to be true. options instead is an object containing 4 properties: Length is a number: it is the length of the password. We need to generate different passwords using different character sets. The puzzle: Keeping Secrets Safe □ĭay 11 of the Dev Advent Calendar □: Today’s problem is about creating passwords. Of different length and difficulty depending on the level of safety. But this time, instead of keys, we will use passwords. Then the elf in charge of the keys always uses the same one.
