I haven’t done any programming with Ethereum so don’t know how developer friendly it is but can safely say that Hyperledger scores an F on the developer experience. Lets try to break down the developer experience on following dimensions:
- Works without any issues
- SDK provides good, exhaustive and bug-free code samples showing how to write code and exercise functionality
- Comprehensive and accurate documentation
- Tech Support: When there is an issue, there is a helpful community to provide support
A – excellent. Scores +1 on all dimensions above
B – Good. Better than other alternatives out there
C – Fair. comparable to other alternative platforms
D – Poor. there exist better alternatives out there
F – Fail. -1 on all of the above dimensions
Hyperledger proudly scores an F
- Broken out of the box: e.g., https://stackoverflow.com/questions/53506205/install-samples-binaries-and-docker-images-not-working-on-mac. Its like you ordered something from amazon and its broken out of the box. Looks like HL team spend no time testing the code works on a mac
- Buggy Samples: e.g., https://stackoverflow.com/questions/51436123/unable-to-find-neweventhub-function. Another example: https://jira.hyperledger.org/browse/FAB-13070
- Samples of limited use and help: e.g.,
- everywhere in the samples they keep on using cryptogen and then write that cryptogen should not be used in production.
- In all the samples, the private crypto keys are blatantly exposed [example] and there is no sample showing how to protect them in a prod environment.
- All the samples create a network in which all the nodes are running on the same computer. There is no sample showing how to create a real-world network spanning multiple computers
- the list goes on and on… basically there is no sample showing how to write a production quality app
- Incorrect documentation: e.g., instructions on https://github.com/hyperledger/fabric-samples/tree/release-1.3/balance-transfer/typescript say that Node.js v6.9.0 – 6.10.0 ( Node v7+ is not supported ) [posting a screenshot below in case it gets fixed later] whereas the instructions for node say that Node.js v8.4.0 or higher. Even the HL Fabric prerequisites say that If you will be developing applications for Hyperledger Fabric leveraging the Hyperledger Fabric SDK for Node.js, you will need to have version 8.9.x of Node.js installed.
In reality Node.js v6.9.0-6.10.0 will land you in trouble. This is because Promises were introduced only in version 8 of Node.
- Tech Support: virtually non-existent. You get what you pay for.
I could go on and add many more examples but above suffice.
