Simple usage example

Checking if a product has been marked.

  //first you need to get a {@link DeveryRegistry} instance
  let deveryRegistryClient = new DeveryRegistry();

  //passing true as param will add the account as marker
  deveryRegistryClient.check("0x627306090abaB3A6e1400e9345bC60c78a8BEf57").then(item => {
       console.log('product brand',item.brandAccount);

  })

  //or with the async syntax

  async function(){
           //passing false as param will remove the account as marker
           let item = await deveryRegistryClient.check("0x627306090abaB3A6e1400e9345bC60c78a8BEf57")
           console.log('product brand',item.brandAccount);

Access to the ethereum network

Devery.js will try to automatically get the web3 object instance present in your context(page, app,etc). If this is not possible then it will fallback to a read only provider poiting to the main network. As the fallback does not contain a signer you will not be able to perform read operations.
