Sannu! A cikin wannan labarin zan nuna muku yadda ake rubutu da gudanar da dApp na yau da kullun akan kullin Waves. Bari mu dubi kayan aikin da ake bukata, hanyoyin da misali na ci gaba.

Yadda ake Gina, Sanya da Gwajin Waves RIDE dApp

Tsarin haɓakawa na dApps da aikace-aikacen yau da kullun kusan iri ɗaya ne:

  • Lambar rubutu
  • Rubutun gwaji ta atomatik
  • Kaddamar da aikace -aikacen
  • Gwaji

Kayan aiki

1. docker don gudanar da node da Waves Explorer

Idan ba kwa son fara kumburi, zaku iya tsallake wannan matakin. Bayan haka, akwai cibiyar sadarwa na gwaji da gwaji. Amma ba tare da ƙaddamar da kumburin ku ba, tsarin gwaji na iya ja.

  • Kuna buƙatar sabbin asusu koyaushe tare da alamun gwaji. Fautar cibiyar sadarwar gwaji tana canja wurin WAVES 10 kowane minti 10.
  • Matsakaicin lokacin toshewa a cikin hanyar sadarwar gwaji shine minti 1, a cikin kumburi - 15 seconds. Wannan abin lura ne musamman lokacin da ma'amala ke buƙatar tabbatarwa da yawa.
  • Ana iya yin caching mai ƙarfi akan nodes na gwaji na jama'a.
  • Hakanan ƙila ba su samuwa na ɗan lokaci saboda kulawa.

Daga yanzu zan ɗauka cewa kuna aiki da kullin ku.

2. Kayan Aikin Layin Layin Surfboard

  • Zazzage kuma shigar da Node.js ta amfani da ppa, homebrew ko exe anan: https://nodejs.org/en/download/.
  • Shigar da Surfboard, kayan aiki wanda ke ba ku damar gudanar da gwaje-gwaje akan kullin da ke akwai.

npm install -g @waves/surfboard

3. Visual Studio Code plugin

Wannan matakin na zaɓi ne idan ba ku da masu sha'awar IDE kuma kun fi son masu gyara rubutu. Duk kayan aikin da ake buƙata sune abubuwan amfani da layin umarni. Idan kuna amfani da vim, kula da plugin ɗin vim-ride.

Kaddamar da node da Waves Explorer

1. Fara kumburi:

docker run -d -p 6869:6869 wavesplatform/waves-private-node

Tabbatar cewa an ƙaddamar da kumburi ta hanyar REST API a ciki http://localhost:6869:

Umurnin yana ƙaddamar da kundin adireshi tare da tsarin aikin, aikace-aikacen "sannu duniya" da gwaje-gwaje. Idan ka bude wannan babban fayil da lambar VS, za ka ga:

Yadda ake Gina, Sanya da Gwajin Waves RIDE dApp
Surfboard.config.json

  • A ƙarƙashin ./ride/ babban fayil za ku sami fayil guda ɗaya wallet.ride - directory inda code dApp yake. Za mu ɗan bincika dApps a cikin toshe na gaba.
  • A ƙarƙashin ./test/ babban fayil za ku sami fayil * .js. Ana adana gwaje-gwaje anan.
  • ./surfboard.config.json – fayil ɗin sanyi don gudanar da gwaje-gwaje.

Envs yanki ne mai mahimmanci. An tsara kowane yanayi kamar haka:

  • REST API na ƙarshen kumburin da za a yi amfani da shi don ƙaddamar da dApp da CHAIN_ID na hanyar sadarwa.
  • Kalmomin sirri don asusu tare da alamun da zasu zama tushen alamun gwajin ku.

Kamar yadda kake gani, surfboard.config.json yana goyan bayan mahalli da yawa ta tsohuwa. Tsohuwar ita ce muhallin gida (maɓallin tsohoEnv shine siga mai canzawa).

Aikace-aikacen walat-demo

Wannan sashe ba magana ce ga harshen RIDE ba. Maimakon haka, duba aikace-aikacen da muke turawa da gwadawa don ƙarin fahimtar abin da ke faruwa a cikin blockchain.

Mu kalli aikace-aikacen demo mai sauƙi na Wallet-demo. Kowa na iya aika alamu zuwa adireshin dApp. Zaku iya janye GUWAN naku kawai. Ana samun ayyuka @Callable guda biyu ta InvokeScriptTransaction:

  • deposit()wanda ke buƙatar biyan haɗe-haɗe a WAVES

Duk tsawon rayuwar dApp, tsarin (adireshin → adadin) za a kiyaye shi:
