app-for-certification

• This React app was initialized with create-near-app.
• The application for passing tests or exams and in a case, you succeed you get certificate which you could print in PDF format or mint and get your certificate with information about your results as NFT.

Quick Start

To run this project locally:

1. Prerequisites: Make sure you've installed Node.js ≥ 12
2. Install dependencies: yarn install
3. Run the local development server: yarn dev (see package.json for a full list of scripts you can run with yarn)

Exploring The Code

1. The "backend" code lives in the /contract folder. See the README there for more info.
2. The frontend code lives in the /src folder. /src/index.html is a great place to start exploring. Note that it loads in /src/index.js, where you can learn how the frontend connects to the NEAR blockchain.
3. Tests: there are different kinds of tests for the frontend and the smart contract. See contract/README for info about how it's tested. The frontend code gets tested with jest. You can run both of these at once with yarn run test.

Deploy

Every smart contract in NEAR has its own associated account. When you run yarn dev, your smart contract gets deployed to the live NEAR TestNet with a throwaway account. When you're ready to make it permanent, here's how.

Step 0: Install near-cli (optional)

near-cli is a command line interface (CLI) for interacting with the NEAR blockchain. It was installed to the local node_modules folder when you ran yarn install, but for best ergonomics you may want to install it globally:

yarn install --global near-cli

Or, if you'd rather use the locally-installed version, you can prefix all near commands with npx

Ensure that it's installed with near --version (or npx near --version)

Step 1: Create an account for the contract

Each account on NEAR can have at most one contract deployed to it. If you've already created an account such as your-name.testnet, you can deploy your contract to app-for-certification.your-name.testnet. Assuming you've already created an account on NEAR Wallet, here's how to create app-for-certification.your-name.testnet:

1. Authorize NEAR CLI, following the commands it gives you:

   near login

2. Create a subaccount (replace YOUR-NAME below with your actual account name):

   near create-account app-for-certification.YOUR-NAME.testnet --masterAccount YOUR-NAME.testnet
