Clone this repository 13 | 14 | ``` 15 | git clone git@github.com:pguso/angular-hardhat-starter-dapp.git 16 | ``` 17 | 18 | 2. Install dependencies 19 | 20 | ``` 21 | npm install 22 | ``` 23 | 24 | 3. Install Metamask (if you not already did) https://metamask.io/download/ 25 | 4. Configure Polygon in Metamask https://docs.matic.today/docs/develop/metamask/config-polygon-on-metamask/ (switch to the Mumbai-Testnet Tab) 26 | 5. Rename .env.dist to .env and paste your Metamask private key into PRIVATE_KEY 27 | 6. Upload the contract to the Polygon Mumbai Testnet, make sure you have enough MATIC in Metamask (you can get test MATIC from here https://faucet.polygon.technology/) 28 | 29 | ``` 30 | npm run deploy:testnet 31 | ``` 32 | 33 | 7. Paste the contract address, you get on the command line, into src/environments/environment.ts 34 | 35 | ```typescript 36 | export const environment = { 37 | // ... 38 | contractAddress: '0x04215C89a6af0f7ed9103c48BaF6A8e19f119470', 39 | // ... 40 | }; 41 | ``` 42 | 43 | 8. Run angular application and test the app under http://localhost:4200 44 | 45 | ``` 46 | ng serve 47 | ``` 48 | 49 | ## This template has three pages 50 | 51 | ### The Homepage 52 | 53 | A list of all uploaded images. 54 | 55 | ### The authors page 56 | 57 | Only images are shown on this page that are uploaded by the selected account in Metamask. 58 | 59 | ### The upload form 60 | 61 | Here anybody who is connected via Metamask can upload an image with title and description. The image and the image metadata get uploaded to IPFS. 62 | 63 | ## Hardhat config 64 | 65 | The default config hardhat.config.js is configured for the Polygon Network. Here you find examples for other Blockchains. 66 | 67 | ### Binance Smart Chain 68 | 69 | ```javascript 70 | require('@nomiclabs/hardhat-waffle') 71 | require('dotenv').config() 72 | 73 | const privateKey = process.env.PRIVATE_KEY 74 | 75 | module.exports = { 76 | networks: { 77 | hardhat: { 78 | chainId: 1337, 79 | }, 80 | testnet: { 81 | url: 'https://data-seed-prebsc-1-s1.binance.org:8545', 82 | chainId: 97, 83 | gasPrice: 20000000000, 84 | accounts: [privateKey], 85 | }, 86 | mainnet: { 87 | url: 'https://bsc-dataseed.binance.org/', 88 | chainId: 56, 89 | gasPrice: 20000000000, 90 | accounts: [privateKey], 91 | }, 92 | }, 93 | solidity: '0.8.4', 94 | } 95 | ``` 96 | -------------------------------------------------------------------------------- /angular.json: -------------------------------------------------------------------------------- 1 | { 2 | "$schema": "./node_modules/@angular/cli/lib/config/schema.json", 3 | "version": 1, 4 | "newProjectRoot": "projects", 5 | "projects": { 6 | "angular-dapp": { 7 | "projectType": "application", 8 | "schematics": { 9 | "@schematics/angular:component": { 10 | "style": "scss" 11 | }, 12 | "@schematics/angular:application": { 13 | "strict": true 14 | } 15 | }, 16 | "root": "", 17 | "sourceRoot": "src", 18 | "prefix": "app", 19 | "architect": { 20 | "build": { 21 | "builder": "@angular-devkit/build-angular:browser", 22 | "options": { 23 | "outputPath": "dist/angular-dapp", 24 | "index": "src/index.html", 25 | "main": "src/main.ts", 26 | "polyfills": "src/polyfills.ts", 27 | "tsConfig": "tsconfig.app.json", 28 | "inlineStyleLanguage": "scss", 29 | "assets": [ 30 | "src/favicon.ico", 31 | "src/assets" 32 | ], 33 | "styles": [ 34 | "./node_modules/@angular/material/prebuilt-themes/deeppurple-amber.css", 35 | "src/styles.scss" 36 | ], 37 | "scripts": [] 38 | }, 39 | "configurations": { 40 | "production": { 41 | "budgets": [ 42 | { 43 | "type": "initial", 44 | "maximumWarning": "500kb", 45 | "maximumError": "1mb" 46 | }, 47 | { 48 | "type": "anyComponentStyle", 49 | "maximumWarning": "2kb", 50 | "maximumError": "4kb" 51 | } 52 | ], 53 | "fileReplacements": [ 54 | { 55 | "replace": "src/environments/environment.ts", 56 | "with": "src/environments/environment.prod.ts" 57 | } 58 | ], 59 | "outputHashing": "all" 60 | }, 61 | "development": { 62 | "buildOptimizer": false, 63 | "optimization": false, 64 | "vendorChunk": true, 65 | "extractLicenses": false, 66 | "sourceMap": true, 67 | "namedChunks": true 68 | } 69 | }, 70 | "defaultConfiguration": "production" 71 | }, 72 | "serve": { 73 | "builder": "@angular-devkit/build-angular:dev-server", 74 | "configurations": { 75 | "production": { 76 | "browserTarget": "angular-dapp:build:production" 77 | }, 78 | "development": { 79 | "browserTarget": "angular-dapp:build:development" 80 | } 81 | }, 82 | "defaultConfiguration": "development" 83 | }, 84 | "extract-i18n": { 85 | "builder": "@angular-devkit/build-angular:extract-i18n", 86 | "options": { 87 | "browserTarget": "angular-dapp:build" 88 | } 89 | }, 90 | "test": { 91 | "builder": "@angular-devkit/build-angular:karma", 92 | "options": { 93 | "main": "src/test.ts", 94 | "polyfills": "src/polyfills.ts", 95 | "tsConfig": "tsconfig.spec.json", 96 | "karmaConfig": "karma.conf.js", 97 | "inlineStyleLanguage": "scss", 98 | "assets": [ 99 | "src/favicon.ico", 100 | "src/assets" 101 | ], 102 | "styles": [ 103 | "./node_modules/@angular/material/prebuilt-themes/deeppurple-amber.css", 104 | "src/styles.scss" 105 | ], 106 | "scripts": [] 107 | } 108 | } 109 | } 110 | } 111 | }, 112 | "defaultProject": "angular-dapp" 113 | } 114 | -------------------------------------------------------------------------------- /contracts/Gallery.sol: -------------------------------------------------------------------------------- 1 | // SPDX-License-Identifier: MIT 2 | pragma solidity >=0.7.0 <0.9.0;
