shorturlsolidity's Introduction
- An implementation of a Short Url service (REST API) using Node, Express, Solidity/Web3
- Compiles contract with
solc
- Deployment is via Web3 (not using truffle)
- Make sure you're running the latest version of node -
node -v
- Install ganache-cli globally -
npm install -g ganache-cli
- Install other dependencies in package.json -
npm install
- Have testrpc running in one terminal window -
ganache-cli
- In another terminal window run -
node deployContract
- Run
node app
Endpoints - via http://localhost:3000
POST '/' - (Returns Shortened Url Key)
http://localhost:3000/- Send a JSON payload with a url property (ex.
{ "url": "www.google.com"})
- This will return a url with the Shortened Url Key (ex.
http://localhost:3000/UtFhjsP8)
GET '/:shortenedUrlKey' - (Redirects to corresponding URL)
- Send a GET request with Shortened Url Key after slash
- If using the key from the URL from the POST endpoint -
http://localhost:3000/UtFhjsP8
- Hashing an original url via sha256
- Encoding that hash to base64 and using the first 8 characters as the Shortened Url Key
- (64^8 = 281,474,976,710,656 possible combinations)
- Use recursive function to generate a new key if it already exists in storage in the contract
- Store Shortened Url Keys as
bytes8 in solidity contract and original url (undetermined length) as bytes
