This summary is from Lin Guopeng.

Compile

When he build the Kuai, the error sizzele error comes out. To solve this problem, he added the dom to the tsconfig.json in cli package.

Deploy the Node

There is something wrong in Mac.

kuai node start
<jemalloc>: MADV_DONTNEED does not work (memset will be used instead)
<jemalloc>: (This is the expected behaviour if you are running under QEMU)

node:internal/process/promises:288
            triggerUncaughtException(err, true /* fromPromise */);
            ^
AxiosError: socket hang up
    at connResetException (node:internal/errors:720:14)
    at Socket.socketOnEnd (node:_http_client:525:23)
    at Socket.emit (node:events:529:35)
    at endReadableNT (node:internal/streams/readable:1368:12)
    at process.processTicksAndRejections (node:internal/process/task_queues:82:21) {
  code: 'ECONNRESET',
...

1. kuai node start --port 8200 the port is useless in this command.
2. Users don't know the private key of the Node, and they should to enter into the container to find the private key from the config file of ckb.
3. When the node starts, there is no omnilock script in config. Should users to add the config to predefined.config of lumos in the devnet?

Deploy the Contract

1. The version of capsule in capsule.toml is 0.9.0 which is generated in running kuai init. So maybe it is necessary to tell users to upgrade the capsule to the version 0.9.0.

cargo install ckb-capsule --git https://github.com/nervosnetwork/capsule.git --tag v0.9.0

2. The ckb-cli should be installed before deploying the contract, and the private key should be imported to the ckb-cli.

ckb-cli account import  --privkey-path  ac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80.json

lock_arg: 0x5bffb3764d38d9f46c1cd2c888cc4d9ca3a9ed0d

3. It is not easy for most fresh users to build the contract.json by the transaction hash which is returned from the transcation of contract deployment.

{
  "kuai-mvp-contract": {
    "depType": "code",
    "outPoint": {
      "txHash": "0x005a153ec6a35adbc8d82544ae11d8c6f8c0601fc9059f8a872e01f638fc9f62",

The MVP

1. the npm run dev could exist caused by the timeout of calling ckb.

npm run dev

2. Unit test should be added to the MVP project.
3. It is not timely for model to update the chainData when call the api /meta/:address.
4. Is it necessary to explain how does the model update the data?
5. It is convenient for users to learn how to write unit tests by adding a valid address of /load:address` in mvp unit tests.
6. Users may need to learn the moleculec which is used in the MVP contract.
7. The MVP contract may use the moleculec, but I did not see any serializing and deserializing in the project. Is it a json string?

Something more in kuai/models

1. Comments should be added into the Store class to explain the meanings of the parameters.

2. kuai/packages/models/src/store/store.ts

   Lines 52 to 74 in 879251f

   	protected states: Record<OutPointString, GetStorageStruct<StructSchema>> = {}
