Providers

Providers are the blockchain connectors. A provider is instantiated internally based on the network name provided on initialization.
Available Providers
LocalProvider
JungleProvider
Jungle3Provider
BosProvider
WorbliProvider
KylinProvider
MainProvider
CustomProvider
const eoslime = require('eoslime').init('jungle') -> JungleProvider
Properties
network
{
    name: 'network name',
    url: 'node endpoint',
    chainId: 'chain id'
}
defaultAccount
The default/main account from which the blockchain transactions are executed
eos
eosjs instance that serves as a bridge with the blockchain
​
Functions
reset
Reset the provider to another one
If you reset the provider, the whole eoslime and all of it's objects will change entirely the old provider with the new one
const eoslimeInstance = eoslime.init();
​
const localProvider = eoslimeInstance.Provider;
assert(JSON.stringify(localProvider.network) == JSON.stringify(Networks.local));
​
const localAccount = await eoslimeInstance.Account.createRandom();
assert(JSON.stringify(localAccount.provider.network) == JSON.stringify(Networks.local));
​
const jungleProvider = new eoslimeInstance.Provider('jungle');
eoslimeInstance.Provider.reset(jungleProvider);
​
assert(JSON.stringify(localAccount.provider.network) == JSON.stringify(Networks.jungle));
assert(JSON.stringify(eoslimeInstance.Provider.network) == JSON.stringify(Networks.jungle));
getABI(contractName)
Returns contract ABI in JSON format
const abiJSON = await Provider.getABI('contract name');
getRawWASM(contractName)
Returns raw WASM useful for deploying another contract directly
const rawWASM = await Provider.getRawWASM('contract name');
Query Chain Style
In order to be easier for developers to read from a table we have implemented query chain like table search.
Provider.select('table').from('contract name')
.equal()
.range()
.limit()
.index()
.find();
Every query should ends with find() in order to be executed.
select(tableName)
