Algo Builder Templates

Dapp templates for Algo Builder.

Distributed Applications (dapps) are basically decentralized applications. The templates in this repository are extremely helpful and easy to use. They are designed and implemented to provide aspiring developers a headstart in building dapps on Algorand Blockchain. The templates use algosdk, Algo Builder, Algosigner, Wallet Connect and MyAlgo Wallet

The detailed description about each template and how to properly use them can be found in the docs directory.

Usage

Each template is a single project (with 1 package.json file) comprising of:

• An algob project : used to deploy ASA's, stateless and stateful contracts. Use algob deploy to deploy your /scripts. Sample algob project can be found here, check the project README.md for more details.
• create-react-app: React js application for your frontend of web dApp. You can use the AlgoSigner global object in your app to use it's API's. Example can be found in the default template.

Deployment information (using algob deploy above) is stored in checkpoints (in /artifacts). Checkpoint information is available for user in the React application.

The templates can be easily bootstrap using the algob unbox-template command.

After successfully unboxing the template, please link the algob package in the template directory to use it for running scripts. The steps for the process can be found here.

To learn how to install and use algob, visit Algo Builder.

Quick Start

algob unbox-template <template-name> <destination-directory> --force (flag)

• if destination-directory is not passed then current directory will be used.
• if template-name is not passed, then by default template "/default" is unboxed.
• if --force is passed, then files are overwritten. If it isn't passed, then for each conflicting file, user is made to choose whether to overwrite that file or not.
• if template-name passed is not present as an existing template, the command provides an interactive way to choose from the existing templates.
• The command also asks if the user wants to install the dependencies as a part of the current process.

Available templates

• htlc: There exists a descriptive example explaining how HTLC contracts work with Algo-Builder. It can be found here. Use algob deploy to deploy scripts: which creates and fund HTLC contract account which is defined in assets/htlc.py. Withdraw from the escrow using React frontend (after yarn start).

• shop: Template with two rows to buy tickets: a) Queens Concert (5 ALGO); b) Beyonce Concert (10 ALGO). In this template we demonstrate usage of a payment widget to trigger a purchase (in this case it would be purchasing tickets for a concert). You can connect to the network using different wallets i.e either with MyAlgo Wallet, Wallet Connect or AlgoSigner. To know more about wallet integration read here

• wallet: Demonstrate how to connect to Algorand wallet in browser and interact with smart contracts via wallets.
