Hi Guys

Flow JS Testing functions are very useful to load and organize transactions / script / contracts  
Also to switch from dev / test / prod env, thanks to the addressMap

#### FUNCTIONS

- [getTemplate(file, addressMap, byAddress)](https://docs.onflow.org/flow-js-testing/templates/#gettemplatefile-addressmap-byaddress)
- [getContractCode(name, addressMap)](https://docs.onflow.org/flow-js-testing/templates/#getcontractcodename-addressmap)
- [getTransactionCode(name, addressMap)](https://docs.onflow.org/flow-js-testing/templates/#gettransactioncodename-addressmap)
- [getScriptCode(name, addressMap)](https://docs.onflow.org/flow-js-testing/templates/#getscriptcodename-addressmap)

Would be so nice to get them in FCL

Kind Regards
