Framework for serverless Decentralized Applications using Ethereum, IPFS and other platforms

What is Embark

Embark is a framework that allows you to easily develop and deploy Decentralized Applications (DApps).

A Decentralized Application is a serverless html5 application that uses one or more decentralized technologies.

Embark currently integrates with EVM blockchains (Ethereum), Decentralized Storages (IPFS), and Decentralized communication platforms (Whisper and Orbit). Swarm is supported for deployment.

With Embark you can:

Blockchain (Ethereum)

• Automatically deploy contracts and make them available in your JS code. Embark watches for changes, and if you update a contract, Embark will automatically redeploy the contracts (if needed) and the dapp.
• Contracts are available in JS with Promises.
• Do Test Driven Development with Contracts using Javascript.
• Keep track of deployed contracts; deploy only when truly needed.
• Manage different chains (e.g testnet, private net, livenet)
• Easily manage complex systems of interdependent contracts.

Decentralized Storage (IPFS, Swarm)

• Easily Store & Retrieve Data on the DApp through EmbarkJS. Including uploading and retrieving files.
• Deploy the full application to IPFS or Swarm.
• Import and deploy contracts hosted on Swarm.

Decentralized Communication (Whisper, Orbit)

• Easily send/receive messages through channels in P2P through Whisper or Orbit.

Web Technologies

• Integrate with any web technology including React, Foundation, etc..
• Use any build pipeline or tool you wish, including grunt, gulp and webpack.

$ npm -g install embark

embark's Issues

Serpent support

Suggestion: make minimalAmount configurable

Embark is really nice tool, but it should be more configurable. Having minimalAmount of Wei configurable would be a nice improvement :)

embark deploy should verify if contract actually exists independent of chain.json

When running embark deploy with an outdated chains.json on a fresh blockchain; embark reports that the contract already exists, while it doesn't exist on the chain. I suggest that embark at least verifies that the contract already exists on the chain (using web3.eth.getCode).

deploy: false config not respected

Clone SafeMarket and check out 7a7012827dc4bb686ba75284a48fe4358c8b7901

https://github.com/SafeMarket/dapp/tree/7a7012827dc4bb686ba75284a48fe4358c8b7901

then run embark blockchain and embark run. Multiple contracts that shouldn't deploy will deploy.

dapp chain server / monitor

A dapp developer might like a server which does stuff like this:

• records all events from a set of contracts into an off-chain db, possibly interpreting event sequences to derive additional state (read-only stuff you want to show in the GUI)
• serves the dapp GUI
• acts as a web3 provider for the dev cycle

discuss

run geth with --vmdebug

this should be useful when developing / debugging; as it exposes OOG errors, etc.

The console: true setting in blockchain.yml doesn't open the console (but mines non-stop instead)

do embark demo
cd embark_demo

edit config/blockchain.yml and set console: true

watch your client in the terminal mining non-stop, but never showing the console

pendingTransaction is not a function?

After doing embark / embark demo / embark blockchain:

js error: TypeError: 'pendingTransactions' is not a function [function() {
  var miner_var;

  if (admin.miner === undefined) {
    miner_var = miner;
  }
  else {
    miner_var = admin.miner;
  }

  var minimalAmount = (web3.eth.getBalance(web3.eth.coinbase) >= 1500000000000000000);
  var pendingTransactions = function() {
    if (web3.eth.pendingTransactions === undefined) {
      return txpool.status.pending || txpool.status.queued;
    }
    else {
      return web3.eth.pendingTransactions().length > 0;
    }
  }

  if(!web3.eth.mining && (!minimalAmount || pendingTransactions())) {
    if (!minimalAmount) { console.log("=== minimal ether amount not reached yet") }
    if (pendingTransactions()) { console.log("=== there are pending transactions") }
    console.log("=== start mining");
    miner_var.start();
  }
  else if (web3.eth.mining && minimalAmount && !pendingTransactions()) {
    if (minimalAmount) { console.log("=== minimal ether amount reached") }
    if (!pendingTransactions()) { console.log("=== no pending transactions") }
    console.log("=== stop mining");
    miner_var.stop();
  }
}]

Suggestion: configure which contracts should be deployed.

It would be nice to choose which contracts should be deployed in certain environment

eg.

contracts:
  - hello.sol/Hello
  - hello.sol/World
  - my_contract.sol/Contract
  - all.sol/*

By default all contracts should be deployed (same as now).

configuration option to not deploy a specific contract in contracts.yml

How can I prevent the class contract which is instantiated multiple times from being deployed
as well?

Solution: add a deploy: false field
as a very ugly workaround you could specify address: 0x0 for that contract

[Docs] Be clear what the relationship is with geth & other clients

The docs don't make it clear:

• whether or not it's safe to use embark with a running geth instance, whether that's wise, etc.
• whether or not a running geth instance is required
• whether or not embark works with arbitrary ethereum clients
• whether or not embark runs its own ethereum client/node
• whether or not embark shares any data with any existing ethereum clients

Additionally, the "Deploying to the testnet" documentation does not, at all, talk about:

• whether a running ethereum client is needed, and if so, which one
• what to do if your existing ethereum client is on the main net
• whether or not embark has its own built-in ethereum client that it uses, and if so, where it stores its data

Fatal error: Port 35729 is already in use by another process.

(with embark 0.4.3)

Changing a contract file while running embark run throws a livereload error. changing a js or html file doesn't give any problems.

I tried removing /tmp/* but it didn't help. I do not know if this issue is caused by embark. Maybe geth cli changed.

node-sleep

Hi, "npm install embark-framework -g" doesn't work under my clean Ubuntu 14.04, because node-sleep^2.0.0 is included. Can you include ^3.0.0, so that this error message is avoided in future:

sudo npm install embark-framework -g

Thank you,

ability to unlock multiple accounts

on geth you can unlock multiple accounts by specifying them as space separated value to the --unlock argument. the `config/password/ file should then contain one password per line.

for development purposes it would be useful to be able to automate this on embark blockchain, allowing you to switch between different accounts on non-trivial dapps.

embark spec requires jasmine

(with embark 0.4.3)

$ embark spec
/bin/sh: jasmine: command not found

Workaround, manually install jasmine globally:

npm install -g jasmine

add config option to specify geth cmd

embark deploy TypeError: Cannot read property 'length' of undefined

With embark 0.8.0 and meteor, it occasionally throws:

Running embark deploy a 2nd time works fine.

"watch" task never sees transactions

Using embark / embark demo / embark blockchain / embark run
Then I go in a browser and set the value. I see the transaction hit the blockchain log. But embark run never sees it...? Also if I reload the browser window and click "Get Value", it's empty.

embark deploy creates empty abi.js if contract is unchanged and already deployed

With embark 0.8.1 and using a newly generated embark_demo project:

web3 should not be initialized inside lib modules

If we want modules in lib/ to be reusable and composable, they can't each set their own web3 provider.
They should accept an initalized web3. Actually, we need a web3 wrapper which is lazily and intelligently initialized, acts as a mock, etc, uses promises, etc.

Trouble when compiling contracts, clarification of contracts.yml

I've been attempting to compile multiple contracts together using embark run, and I keep getting the same warning/error, even though when run together via the command line compiler, they compile perfectly, leading me to believe that this is something to do with embark and not necessarily the solidity files:

    Running "deploy_contracts" task
    primary account address is : 0xbc2e8acaef6b3c63a4b34773b8a21e66a39bee9f
    address is : 0xbc2e8acaef6b3c63a4b34773b8a21e66a39bee9f
    Warning: solc error: exit status 1 Use --force to continue.

since then I've tried fiddling with the contracts.yml, but I haven't been able to figure this out just yet. So I'm asking moreso for a clarification here. Do I need to declare all of my contracts in the .yml config file? Do I need to specify arguments if they contain them? What might be causing this error? Does embark currently support multiple contracts being compiled together on the same platform? Let me know. Thank you again.

I would expect the mining to stop after the first Account funded message, waiting for new transactions before resuming (as it used to be the case in embark 0.8.6). Instead it keeps on mining.

Suggestion: Framework contracts

Imagine if this framework included a set of simple contracts to be deployed with your DApp that interact with the registrar and perhaps include an infoHash of the deployed app, to enable p2p fetching and hosting of the DApp.

I suppose, this might be application specific in most cases, but theres definitely room to be more framework than utility, which I feel it is at the moment (albeit a very useful one).

chains.json doesn't work nice with version control

embark version 0.8.0 now requires the chains.json file to be present in the project root directory. Minimally it contains {}, but will be updated over time to track contract deployments.

Now I don't want this file to be under version control (which would trigger unwanted commits / merge conflicts), so I would put it in .gitignore, but unfortunately embark deploy doesn't generate the file if it is missing (with the minimum {} default content), instead giving the error:

Running "deploy_contracts:development" (deploy_contracts) task
Warning: error reading ./chains.json Use --force to continue.

I can add manual installation instructions for developers, to generate the file, but ideally the file should be generated by default and/or reside outside of the project root directory.

Configure gruntfile to issue minified versions only on deploy/dynamic dapp capabilities

This is a simple thing to get done. Unfortunately, I am not big on .coffee scripts and have opted instead to convert them into .js scripts so if I make a PR, perhaps translation is necessary for a merge?

I think that when developing, a minified version is a handicap, not a benefit, as they are obviously impossible to read, so my suggestion would be to make the pre installed Gruntfile only deploy a minified version if the deploy command is actually called. For testing purposes, it should take the files as they are and push them into the generated dapp folder.

My second proposal is to automatically apply the express server with a view engine capable of dynamic dapps. This too is simple to do and I can get a PR request to you on that soon.

Any thoughts?

Ctrl+C on Ubuntu 14.04 LTS doesn't kill geth, geth takes massive amounts of CPU

@iurimatias I've already made this issue clear via Gitter, but I want to see if there would be other people willing to help tackle this.

This happens after I try to end the session following a embark blockchain command. It kills geth in the shell, however, geth is not dead and lives. PIDs show that it takes up to 50% of CPU resources. Prior to this, the automatic miner works just as you would expect. It's kind of an annoyance having to go into the task manager and seek out and kill geth, so any and all help in solving this is greatly appreciated. Much thanks guys.

Convert to promises or something async

It doesn't work for me. I'm running Ubuntu 14.10, embark 0.7.0, geth 0.9.39
This seems like a really bad way to implement it (but then, I was told it was a hack, so, eh..)

lib/deploy.js

      while ((receipt = web3.eth.getTransactionReceipt(transactionHash)) === null) {
          sleep.sleep(1);
      }

Sometimes I get "CONNECTION ERROR" (and sometimes it just quietly returned back to my shell without doing anything), I think web3 just trying over and over again to do JSON-RPC to geth. I tried to convert this into a way to use the callbacks on the .new() call to a contract that tell you the address, but then everything else broke. (Such as when it goes to write the ABI, it wasn't waiting for the transaction to finish being deployed, it was depending on this loop to repeat.)

I'm not sure what the best way to fix all of this is, unfortunately I'm not a JS expert. :-(

Good luck converting it to promises/async stuff.

use bunyan for logging

especially if you tackle #28

Contract dependencies

Currently (as far as I understand), embark assumes that each solidity file in the contracts folder is completely independent and self contained. This will be false for anything but the simplest code bases. Would it be possible to support the import keywords? I.e. If a contract solidity file imports another file, then concatenate the two files before sending them to the compiler.

Additionally, a bigger project will contain a lot of helper contracts that are used as interfaces or base contracts inherited from. These should not be deployed. Even if I don't specify these contracts in the contract.yaml file, embark still deploys them, which is imho undesired behavior.

instance variable not defined in onDeploy

with embark 0.8.6, with the following contracts.yml:

development:
  MinHeap:
    args:
  BidsHeap:
    instanceOf: MinHeap
    gas_limit: 600000
  AsksHeap:

    gas_limit: 600000
  Market:
   args:
    onDeploy:
      - Market.initialize($BidsHeap, $AsksHeap)

I get the exception upon deployment:

I would expect that $BidsHeap would point to the address of the BidsHeap instance of the MinHeap contract.

block timestamp wrong on development chain

error handling when solc is not found

When solc is not present on the system, embark run fail with the following error:

Warning: Cannot call method 'slice' of undefined Use --force to continue.

build pipeline features

Parent issue for figuring out high-level build process for contract systems.

• Solidity preprocessing: there are a few compelling use cases for c-style preprocessor macros. You could actually just use gcc for this.
• Singleton contract awareness: The deploy process should be aware of contracts which are only deployed once within a blockchain. These can be categorized "external apps" (eg namereg) and "factory contracts"
• sufficiently expressive declarative build format: is a contract dependency graph enough?
• Better testing: Use the evm as one possible test environment for contract tests. Maybe js-based tests should be restricted to frontend integration testing

using 'className' in Deploy.deployedContracts is not reliable

Because of this line deploy will fail everytime when:

• one contract is deployed twice (via config/contracts.yml)
• two contracts (in different files) have the same contract name

The solution is to make Deploy.deployedContracts an object where:

• key is transactionHash
• value is an object with fields:
  • class
  • file (for logs readability)
  • address

eg:

{
  "0x230366eb93a55766d8c73188aaf7869b8c343a6ee0e8de43fc9d888ef4b83070":
  {
    "class": "SimpleContract",
    "file": "simple_contract.sol",
    "address": "0x096c0cda9103c9641f2b94fa28ed8827426c445a"
  }
}

make deploy timeout configurable per environment

refactor all sync and callback code uses to promises

I think everything in lib/ should use promises. Objections?
