Lumela! Sehloohong sena ke tla u bontša mokhoa oa ho ngola le ho tsamaisa dApp e tloaelehileng ho node ea Waves. A re shebeng lisebelisoa tse hlokahalang, mekhoa le mohlala oa tsoelo-pele.
Sekema sa nts'etsopele ea dApps le lits'ebetso tse tloaelehileng se batla se tšoana:
- Ho ngola khoutu
- Ho ngola tlhahlobo e iketsang
- Ho qala ts'ebeliso
- Teko
Lisebelisoa
1. docker ho tsamaisa node le Waves Explorer
Haeba u sa batle ho qala node, u ka tlola mohato ona. Ntle le moo, ho na le marang-rang a liteko le liteko. Empa ntle le ho sebelisa node ea hau, ts'ebetso ea tlhahlobo e ka 'na ea tsoela pele.
- U tla lula u hloka li-account tse ncha tse nang le li-tokens tsa liteko. Teko ea marang-rang ea liteko e fetisetsa WAVES tse 10 metsotsong e meng le e meng e 10.
- Karolelano ea nako ea ho thibela marang-rang ea teko ke metsotso e 1, ka node - metsotsoana e 15. Sena se bonahala haholo ha khoebo e hloka litiisetso tse ngata.
- Caching e matla e ka khoneha libakeng tsa tlhahlobo ea sechaba.
- Li ka 'na tsa se be teng ka nakoana ka lebaka la tlhokomelo.
Ho tloha joale ho ea pele ke tla nka hore u sebetsa ka node ea hau.
2. Surfboard Command Line Tool
- Khoasolla le ho kenya Node.js u sebelisa ppa, homebrew kapa exe mona: .
- Kenya Surfboard, sesebelisoa se u lumellang ho etsa liteko sebakeng se seng se le teng.
npm install -g @waves/surfboard
3. Visual Studio Code plugin
Mohato ona ke oa boikhethelo haeba ha u morati oa li-IDE 'me u khetha bahlophisi ba mongolo. Lisebelisoa tsohle tse hlokahalang ke lisebelisoa tsa line line. Haeba u sebelisa vim, ela hloko plugin .
Khoasolla le ho kenya Khoutu ea Visual Studio:
Bula Khoutu ea VS 'me u kenye plugin ea wave-ride:
Katoloso ea sebatli sa Waves Keeper:
E entsoe!
Qala node le Waves Explorer
1. Qala node:
docker run -d -p 6869:6869 wavesplatform/waves-private-node
Etsa bonnete ba hore node e qalisoa ka REST API ho :
Swagger REST API bakeng sa node
2. Qala mohlala oa Waves Explorer:
docker run -d -e API_NODE_URL=http://localhost:6869 -e NODE_LIST=http://localhost:6869 -p 3000:8080 wavesplatform/explorer
Bula sebatli 'me u ee ho . U tla bona hore na potoloho ea node ea sebaka se se nang letho e hahiloe kapele hakae.
Waves Explorer e bonts'a mohlala oa node ea lehae
Sebopeho sa RIDE le sesebelisoa sa Surfboard
Etsa buka e se nang letho 'me u tsamaise taelo ho eona
surfboard init
Taelo e qala bukana e nang le sebopeho sa morero, "hello world" lits'ebetso le liteko. Haeba u bula foldara ena ka VS Code, u tla bona:
Surfboard.config.json
- Tlas'a ./ride/ foldara u tla fumana faele e le 'ngoe wallet.ride - bukana moo khoutu ea dApp e leng teng. Re tla sekaseka dApps ka bokhuts'oane sebakeng se latelang.
- Tlas'a ./test/ foldara u tla fumana *.js faele. Liteko li bolokiloe mona.
- ./surfboard.config.json - faele ea tlhophiso bakeng sa liteko tse sebetsang.
Envs ke karolo ea bohlokoa. Tikoloho e 'ngoe le e' ngoe e hlophisitsoe ka tsela ena:
- REST API pheletso ea node e tla sebelisoa ho qala dApp le CHAIN_ID ea marang-rang.
- Polelo ea lekunutu bakeng sa ak'haonte e nang le li-tokens tse tla ba mehloli ea matšoao a hau a tlhahlobo.
Joalokaha u bona, surfboard.config.json e ts'ehetsa libaka tse ngata ka mokhoa o ikhethileng. Ntho e sa fetoheng ke tikoloho ea lehae (senotlolo sa defaultEnv ke parameter e fetohang).
Sesebelisoa sa Wallet-demo
Karolo ena ha e bue ka puo ea RIDE. Sebakeng seo, sheba ts'ebeliso eo re e sebelisang le ho e leka ho utloisisa hantle se etsahalang ho blockchain.
Ha re shebeng ts'ebeliso e bonolo ea Wallet-demo. Mang kapa mang a ka romella li-tokens atereseng ea dApp. U ka hula MAFUTA a hau feela. Mesebetsi e 'meli ea @Callable e fumaneha ka InvokeScriptTransaction:

Malebela a mang a Surfboard:
1. Ho etsa liteko tikolohong ea testnet, sebelisa:

Ho sebelisa lisebelisoa tse nang le Waves Keeper
1. Hlophisa Waves Keeper ho sebetsa:
Ho theha Waves Keeper ho sebetsa le node ea lehae
2. Kenya poleloana ea lekunutu ka li-tokens tsa marang-rang? Ho nolofatsa, sebelisa peo ea pele ea node ea hau: waves private node seed with waves tokens. Aterese: 3M4qwDomRabJKLZxuXhwfqLApQkU592nWxF.
3. U ka tsamaisa ts'ebeliso ea leqephe le le leng ntle le seva u sebelisa npm. Kapa u ee ho e teng:
