Photo storage example
View this sample's code on GitHub
The example shows how to store photos on BIG in an asset canister with the @dfinity/assets package. The photo
storage app is deployed as a frontend in an asset canister which is also used for photo upload.
This example project can be cloned, installed, and deployed locally, for learning and testing purposes. The instructions are based on running the example on either macOS or Linux, but when using WSL2 on Windows, the instructions will be the same.
Prerequisites
This example requires an installation of:
Install
Clone the example dapp project:
git clone https://github.com/dfinity/examples
cd examples/hosting/photo-storage
React build
The React frontend is built by running:
npm install
npm run build
Deployment
The local replica is started by running:
dfx start --clean --background
When the local replica is up and running, run this command to deploy the canisters:
dfx deploy
Authorization
To authorize an identity to upload files, it must be authorized first:
dfx canister call photo-storage authorize '(principal "535yc-uxytb-gfk7h-tny7p-vjkoe-i4krp-3qmcl-uqfgr-cpgej-yqtjq-rqe")'
Before deployment on BIG, the hardcoded identity (defined in src/App.js) should be replaced by an authentication
method such as Internet Identity.
Example photos
The example cat stock photos are from Pexels.
