The Community Garden Management System is a web application designed to facilitate the management of community gardens. It allows users to reserve plots, track gardening activities, schedule maintenance tasks, and share resources. The platform includes features for user profiles, plot reservations, activity tracking, resource sharing, and community events.

To get started developing in the browser, click this button:

If you rather want to use GitHub Codespaces, click this button instead:

NOTE: After dfx deploy, when developing in GitHub Codespaces, run ./canister_urls.py and click the links that are shown there.

If you prefer running VS Code locally and not in the browser, click "Codespaces: ..." or "Gitpod" in the bottom left corner and select "Open in VS Code" in the menu that appears. If prompted, proceed by installing the recommended plugins for VS Code.

To develop fully locally, first install Docker and VS Code and start them on your machine. Next, click the following button to open the dev container locally:

1. Install nvm:

• curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash

2. Switch to node v20:

• nvm install 20
• nvm use 20

3. Install build dependencies:

sudo apt-get install podman

xcode-select --install brew install podman

4. Install dfx

• DFX_VERSION=0.16.1 sh -ci "$(curl -fsSL https://sdk.dfinity.org/install.sh)"

5. Add dfx to PATH:

• echo 'export PATH="$PATH:$HOME/bin"' >> "$HOME/.bashrc"

6. Create a project structure:

• create src dir
• create index.ts in the src dir
• create tsconfig.json in the root directory with the next content

{ "compilerOptions": { "allowSyntheticDefaultImports": true, "strictPropertyInitialization": false, "strict": true, "target": "ES2020", "moduleResolution": "node", "allowJs": true, "outDir": "HACK_BECAUSE_OF_ALLOW_JS" } }

• create dfx.json with the next content

{ "canisters": { "community_garden_management": { "type": "custom", "main": "src/index.ts", "candid": "src/index.did", "candid_gen": "http", "build": "npx azle community_garden_management", "wasm": ".azle/community_garden_management/community_garden_management.wasm", "gzip": true, "metadata": [ { "name": "candid:service", "path": "src/index.did" }, { "name": "cdk:name", "content": "azle" } ] } } }

where community_garden_management is the name of the canister.

6. Create a package.json with the next content and run npm i:

{ "name": "community_garden_management", "version": "0.1.0", "description": "Internet Computer message board application", "dependencies": { "@dfinity/agent": "^0.21.4", "@dfinity/candid": "^0.21.4", "azle": "^0.21.1", "express": "^4.18.2", "uuid": "^9.0.1" }, "engines": { "node": "^20" }, "devDependencies": { "@types/express": "^4.17.21" } }

7. Run a local replica

• dfx start --host 127.0.0.1:8000

If you make any changes to the StableBTreeMap structure like change datatypes for keys or values, changing size of the key or value, you need to restart dfx with the --clean flag. StableBTreeMap is immutable and any changes to it's configuration after it's been initialized are not supported.

• dfx start --host 127.0.0.1:8000 --clean

8. Deploy a canister

• dfx deploy Also, if you are building an HTTP-based canister and would like your canister to autoreload on file changes (DO NOT deploy to mainnet with autoreload enabled):

AZLE_AUTORELOAD=true dfx deploy

9. Stop a local replica

• dfx stop

When a canister is deployed, dfx deploy produces a link to the Candid interface in the shell output.

Candid interface provides a simple UI where you can interact with functions in the canister.

On the other hand, you can interact with the canister using dfx via CLI:

• dfx canister id <CANISTER_NAME> Example:
• dfx canister id community_garden_management Response:

bkyz2-fmaaa-aaaaa-qaaaq-cai

Now, the URL of your canister should like this:

http://bkyz2-fmaaa-aaaaa-qaaaq-cai.localhost:8000

With this URL, you can interact with the canister using an HTTP client of your choice.
