Practicing React Component classes, states, props, and AWS Polly. 16 | - This project is far from perfect. I decided to practice some basic ideas about accessibility by implementing full control via keyboard/mouse. 17 | - This project is also a practice implementation for the AWS service [Amazon Polly](https://aws.amazon.com/polly/) 18 | 19 | 20 | ## How to use it. 21 | 22 | ### Normal operation 23 | 24 | - You can use the calculator by clicking on the buttons or touch screen device as a standard calculator. 25 | - You can key the numbers and operations using the keyboard. 26 | #### Special Keys: 27 | - ```Enter``` => '=' 28 | - ```delete/backspace``` => 'AC' 29 | - ```_``` => '+/-' 30 | - ``` / ``` => Division symbol 31 | - ``` * or x ``` => Multiplication Symbol 32 | 33 | ### Activate Text to Speech functionality: 34 | - Touch/Click: Speech function is activated clicking/touching the button `Speech`. 35 | - Keyboard: Typing the key 's' (lower case) 36 | - On activation, you will hear a voice with an activation message en English (default language). 37 | - A Icon ![](./src/assets/icons/speech.svg) will appear on display to indicate the Text to Speech activation. 38 | 39 | ### Change text to speech-language : Spanish / English 40 | - Touch/Click: on buttons `En` or `Sp` for language toggling. 41 | - Keyboard: Typing the key 'l' (lower case) for language toggling. 42 | - On Toggling, you will hear a voice on the selected language. The proper Icons will appear on Display. 43 | 44 | ### Push To Talk functionality: PTT 45 | - Touch/Click: on PTT button for PTT function activation. 46 | - Keyboard: Typing the key 'p' (lower case) for the push to talk function. 47 | - On activation, this function will read out loud the Display contents. 48 | - A similar effect can be achieved by using the '=' sign. 49 | 50 | ## Built With 51 | 52 | - React.js, Webpack, Babel 53 | - HTML5/CSS3, Javascript ES6 54 | - ESlint, Stylelint 55 | - VSCode 56 | - AWS Polly 57 | 58 | 59 | ## Getting Started 60 | 61 | 62 | This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app). 63 | 64 | 65 | To get a local copy up and running, follow these simple example steps. 66 | 67 | ### Prerequisites 68 | 69 | ### Amazon Polly Setup 70 | 71 | - Create a ```.env``` file in the root of the project and include your own AWS Amazon Polly credentials. YOu can use as reference the file included in the repo ```.env.example``` 72 | 73 | ``` 74 | REACT_APP_AWS_ACCESS_KEY_ID = '' 75 | REACT_APP_AWS_SECRET_ACCESS_KEY = '' 76 | ``` 77 | 78 | ## Install 79 | 80 | ### `yarn start` 81 | 82 | Runs the app in the development mode.
83 | Open [http://localhost:3000](http://localhost:3000) to view it in the browser. 84 | 85 | The page will reload if you make edits.
86 | You will also see any lint errors in the console. 87 | 88 | ### `yarn build` 89 | 90 | Builds the app for production to the `build` folder.
91 | It correctly bundles React in production mode and optimizes the build for the best performance. 92 | 93 | The build is minified and the filenames include the hashes.
94 | Your app is ready to be deployed! 95 | 96 | See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information. 97 | 98 | 99 | ## Authors 100 | 101 | 👤 ***Carlos Anriquez*** 102 | 103 | - Github: [@canriquez](https://github.com/canriquez) 104 | - Twitter: [@cranriquez](https://twitter.com/cranriquez) 105 | - Linkedin: [linkedin](https://www.linkedin.com/in/carlosanriquez/) 106 | - Portfolio: [carlosanriquez.com](https://www.carlosanriquez.com) 107 | 108 | 109 | ## 🤝 Contributing 110 | 111 | Contributions, issues, and feature requests are welcome! 112 | 113 | Feel free to check the [issues page](https://github.com/canriquez/react-calculator/issues). 114 | 115 | ## Show your support 116 | 117 | Give a ⭐️ if you like this project! 118 | 119 | ## Acknowledgments 120 | 121 | - My Family 122 | - The Beagles! 123 | ## 📝 License 124 | 125 | This project is [MIT](./LICENSE) licensed. 126 | -------------------------------------------------------------------------------- /app_screenshot.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/canriquez/react-calculator/7c5ab5e789fa89feae086792aa18843c8cf962f5/app_screenshot.png -------------------------------------------------------------------------------- /package.json: -------------------------------------------------------------------------------- 1 | { 2 | "name": "react-calculator", 3 | "version": "0.1.0", 4 | "private": true, 5 | "scripts": { 6 | "start": "react-scripts start", 7 | "build": "react-scripts build", 8 | "test": "react-scripts test", 9 | "eject": "react-scripts eject" 10 | }, 11 | "eslintConfig": { 12 | "extends": "react-app" 13 | }, 14 | "browserslist": { 15 | "production": [ 16 | ">0.2%", 17 | "not dead", 18 | "not op_mini all" 19 | ], 20 | "development": [ 21 | "last 1 chrome version", 22 | "last 1 firefox version", 23 | "last 1 safari version" 24 | ] 25 | }, 26 | "devDependencies": { 27 | "eslint": "^6.8.0", 28 | "eslint-config-airbnb": "^18.1.0", 29 | "eslint-plugin-import": "^2.20.2", 30 | "eslint-plugin-jsx-a11y": "^6.2.3", 31 | "eslint-plugin-react": "^7.20.6", 32 | "eslint-plugin-react-hooks": "^2.5.1", 33 | "stylelint": "^13.3.3", 34 | "stylelint-config-standard": "^20.0.0", 35 | "stylelint-csstree-validator": "^1.8.0", 36 | "stylelint-scss": "^3.17.2" 37 | }, 38 | "dependencies": { 39 | "@testing-library/jest-dom": "^4.2.4", 40 | "@testing-library/react": "^9.3.2", 41 | "@testing-library/user-event": "^7.1.2", 42 | "aws-sdk": "^2.745.0", 43 | "big.js": "^5.2.2", 44 | "prop-types": "^15.7.2", 45 | "react": "^16.13.1", 46 | "react-dom": "^16.13.1", 47 | "react-gtm-module": "^2.0.10", 48 | "react-scripts": "3.4.3" 49 | } 50 | } 51 | -------------------------------------------------------------------------------- /public/favicon.ico: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/canriquez/react-calculator/7c5ab5e789fa89feae086792aa18843c8cf962f5/public/favicon.ico -------------------------------------------------------------------------------- /public/index.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 12 | 13 | 17 | 18 | 27 | React App 28 | 29 | 30 | 31 |
