EXT

Welcome to your new EXT project and to the Internet Computer development community. By default, creating a new project adds this README and some template files to your project directory. You can edit these template files to customize your project and to include your own code to speed up the development cycle.

To get started, you might want to explore the project directory structure and the default configuration file. Working with this project in your development environment will not affect any production deployment or identity tokens.

To learn more before you start working with EXT, see the following documentation available online:

• Quick Start
• SDK Developer Tools
• Motoko Programming Language Guide
• Motoko Language Quick Reference

If you want to start working on your project right away, you might want to try the following commands:

cd EXT/
dfx help
dfx canister --help

Running the project locally

If you want to test your project locally, you can use the following commands:

# Starts the replica, running in the background
dfx start --background

# Deploys your canisters to the replica and generates your candid interface
dfx deploy

Once the job completes, your application will be available at http://localhost:4943?canisterId={asset_canister_id}.

If you have made changes to your backend canister, you can generate a new candid interface with

npm run generate

at any time. This is recommended before starting the frontend development server, and will be run automatically any time you run dfx deploy.

If you are making frontend changes, you can start a development server with

npm start

Which will start a server at http://localhost:8080, proxying API requests to the replica at port 4943.

Note on frontend environment variables

If you are hosting frontend code somewhere without using DFX, you may need to make one of the following adjustments to ensure your project does not fetch the root key in production:

• setDFX_NETWORK to ic if you are using Webpack
• use your own preferred method to replace process.env.DFX_NETWORK in the autogenerated declarations
  • Setting canisters -> {asset_canister_id} -> declarations -> env_override to a string in dfx.json will replace process.env.DFX_NETWORK with the string in the autogenerated declarations
• Write your own createActor constructor

EXT NFT_STANDARD MOTOKO Canister Installation and Local Deployment

This guide will walk you through the installation and local deployment of an EXT NFT_STANDARD MOTOKO Canister. Please follow the steps carefully to ensure successful deployment and operation.

Prerequisites

• Ensure you have dfx (DFINITY's SDK) installed on your system. You can download it from DFINITY's official site.
• A working knowledge of the command line.
• An Internet Computer identity principal. You can create one using dfx.

Steps

1. Start the Local Internet Computer

First, start the local Internet Computer in the background:

dfx start --background

2. Deploy the Canister

Deploy the canister using the specified ID:

dfx deploy --specified-id bkyz2-fmaaa-aaaaa-qaaaq-cai EXT_backend

During the deployment, you will be asked for the principal of the minter. Use your own principal, which can be obtained using the following command:

dfx identity use anonymous
dfx identity get-principal
dfx identity use `previous-identity`

Copy and paste the principal you get when prompted.

3. Mint an NFT

After the canister is deployed, you can mint an NFT using the following command:

dfx canister call EXT_backend mintNFT '(to :principal  '<principal of user to send the nft>', metadata : "{\22name\22:\22Minimalistic Villas#0\22,\22mimeType\22:\22image\22,\22url\22:\22https://cf-assets.yuku.app/BatchMint/Minimalistic/0.png\22,\22thumb\22:\22https://cf-assets.yuku.app/BatchMint/Minimalistic/0_thumb.png\22,\22description\22:\22This is the NFT from Minimalistic Villas collection\22,\22attributes\22:[{\22trait_type\22:\22Common\22,\22value\22:\22Common\22}]}")'

Example

1. Get your principal:

dfx identity get-principal

2. Replace <principal of user to send the nft> with the principal you want to have the NFT.

3. Run the command to mint the NFT.

Notes

• Make sure your principal is correctly copied and pasted.
• The metadata in the minting command can be customized to match your NFT's attributes.

Troubleshooting

• If you encounter any issues with dfx start, ensure no other instance of the Internet Computer is running.
• Verify your principal by running dfx identity get-principal again if you encounter authentication errors.
