DeveryRegistry

This method gives an estimation of how much gas will be used for the method DeveryRegistry.addBrand the params that you pass to this method shall be exactly the same ones that you would pass to DeveryRegistry.addBrand. the return of this method will be the total gas used to call DeveryRegistry.addBrand with the given parameters. It's important to note that a call to this method will only be successful if the call to DeveryRegistry.addBrand would be a valid call

Creates a new app in the blockchain, each account can have only one account so if your account already have an app you must call updateApp to change its details. This is a write method so you will need to provide some gas to run it, plus keep in mind that your environment need to have access to an signer so make sure that your user have access to metamask or other web3 object.

Usage example:

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


deveryRegistryClient.addApp("Logistics co. app","0x627306090abaB3A6e1400e9345bC60c78a8BEf57",5).then(transaction => {
     console.log('transaction address',transaction.hash);
     //... other stuff
}).catch(err => {
     if(err.message.indexOf('User denied')) {
         console.log('The user denied the transaction');
         //...
     }

     // handle other exceptions here

})


// or with the async syntax

async function foo() {
     try{
         let transaction = await deveryRegistryClient.addApp("Logistics co. app","0x627306090abaB3A6e1400e9345bC60c78a8BEf57",5);

Listener to AppAdded events, this event triggers whenever a new devery app is created in the blockchain. Please note, that AppAddedEventListeners do not stack, this means that whenever you set one you are removing the last one. If you want to remove an AppAddedEventListener, just call this function passing undefined as param.

Usage example:

// first you need to get a DeveryRegistry instance
let deveryRegistryClient = new DeveryRegistry();
// now you can use it


DeveryRegistryClient.setAppAddedEventListener((appAccount,appName,feeAccount,fee,active) => {
     // whenever an app created we will log it to the console
     console.log(`new app created ${appAccount} - ${appName} ...`);
})

// if you want to remove the listener you can simply pass undefined as parameter

DeveryRegistryClient.setAppAddedEventListener(undefined);

// or that is equivalent to the above call

DeveryRegistryClient.setAppAddedEventListener();

The returned promise if resolved will return a ProductData you can click here to check its fields

Returns an array of product addresses from the productAccounts array contained in the smart contract. If you try to access a page that does not exist you will get a promise that resolves to an empty array as result. The parameters page and pagesize are optional.

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

deveryRegistryClient.productAccountsPaginated(0,20).then(addressArr => {
    for(let address of addressArr) {
         console.log(address);
    }
})

// or with the async syntax

async function foo() {
     // here we don't pass any param to productAccountsPaginated
     // because its parameters are optional
     let addressArr = await deveryRegistryClient.productAccountsPaginated();
     for(let address of addressArr) {
         console.log(address);
     }

     //... do more stuff
}

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

deveryRegistryClient.productAccountsArray(4).then(address => {
    deveryClient.getProduct(address).then(product => {
         console.log(product.productDescription);

Returns the total count of product accounts registered on the smart contract. This method is particularly useful to be used in conjunction with productAccountsArray because you can verify the array upper bounds.

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

deveryRegistryClient.productAccountsLength().then(totalProducts => {
    for(let i = 0;i< totalProducts;i++) {
         deveryRegistryClient.productAccountsArray(i).then(address => {
             deveryRegistryClient.getProduct(address).then(product => {
                 console.log(product.productDescription);
                  //... do more stuff
             })
          })
     }
})

// optionally you can use the async syntax if you prefer
const totalProducts = await deveryRegistryClient.productAccountsLength();
for(let i = 0; i < totalProducts; i++) {
    const address = await deveryRegistryClient.productAccountsArray(i);
    const product = await deveryRegistryClient.getProduct(address);
    console.log(product.productDescription);
    //... do more stuff

Listener to productAdded events. This event triggers whenever a new product is created in the blockchain. Please note that ProductAddedEventListeners do not stack, this means that whenever you set one you are removing the last one. If you want to remove a ProductAddedEventListener, just call this function passing undefined as param.

Usage example:

// first you need to get a DeveryRegistry instance
let deveryRegistryClient = new DeveryRegistry();
// now you can use it


deveryRegistryClient.setProductAddedEventListener((productAccount,brandAccount,appAccount,description,active) => {
     // whenever a product created we will log it to the console
     console.log(`a product has been added ${productAccount} - ${brandAccount} ...`);
})

// if you want to remove the listener you can simply pass undefined as parameter
deveryRegistryClient.setProductAddedEventListener(undefined);

// or that is equivalent to the above call
deveryRegistryClient.setProductAddedEventListener();

Listener to productUpdated events. This event triggers whenever a product is updated in the blockchain. Please note that ProductUpdatedEventListeners do not stack, this means that whenever you set one you are removing the last one. If you want to remove a ProductUpdatedEventListener, just call this function passing undefined as param.

Usage example:

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

}).catch(err => {
     if(err.message.indexOf('User denied')) {
         console.log('The user denied the transaction');
         //...
     }

     // handle other exceptions here

})

Creates a new Product in the blockchain and automatically mark it. Calling addProduct and mark separately will have the same result, this is just a wrapper that does both calls on your behalf, that means that once you call this method you will see 2 transactions (1 for add product and 1 for mark). This is a write method so you will need to provide some gas to run it, plus keep in mind that your environment need to have access to an signer so make sure that your user have access to metamask or other web3 object.

Usage example:

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


deveryRegistryClient.AddProductAndMark('0x627306090abaB3A6e1400e9345bC60c78a8BEf57','My nice product','batch 001',2018,'Unknown place').then(transaction => {
     console.log('transaction address',transaction.hash);
     //... other stuff
}).catch(err => {
     if(err.message.indexOf('User denied')) {
         console.log('The user denied the transaction');
         //...
     }

     // handle other exceptions here

})
