Local Playground Setup

we can skip step 7 can import files one by one into playground

1. clone composer: git clone https://github.com/hyperledger/composer
2. bootstrap dependencies: lerna bootstrap
3. init submodules of composer-playground package: git submodule && git submodule update
4. start up composer-playground-api package: node composer/packages/composer-playground-api/cli.js
5. build composer-playground: env PLAYGROUND_API=http://localhost:15699 npm run build (we can change playground api address via process environment variable)
6. start up composer-playground: node composer/packages/composer-playground/cli.js
7. package the examples: composer archive create -a dist/{name}-network.bna --sourceType dir --sourceName .
8. import the bna file into playground

Hyperledger Fabric Deployment

ensure that identity pub/priv keys used in composer profile credentials and fabric (orderer/peer/client)'s admincerts are identical

1. use configtxgen to generate a channel genesis file: configtxgen -profile {GenesisProfile} -outputCreateChannelTx composerchannel.tx -channelID composerchannel
2. create channel composerchannel with orderer
3. peer {composer-peer} join channel composerchannel
4. deploy network archive: composer network deploy -a {networkArchive.bna} -p {connectionProfile} -i {adminId} -s {adminSecret} -o endorsementPolicyFile={endorsementPolicy.json}
5. generate rest api: composer-rest-server -p hlfv1 -i {adminId} -s {adminSecret} -N never -S false -w true -t false -n {businessNetwork}
6. generate angular2 app: yo hyperledger-composer (install yoeman generator by npm -g i generator-hyperledger-composer)
