Aloha! Ma kēia ʻatikala e hōʻike wau iā ʻoe pehea e kākau ai a holo i kahi dApp maʻamau ma kahi node Waves. E nānā kākou i nā mea hana pono, nā ʻano hana a me kahi laʻana o ka hoʻomohala ʻana.
ʻO ka papahana hoʻomohala no nā dApps a me nā noi maʻamau ua aneane like:
- Kākau helu
- Ke kākau ʻana i ka hoʻāʻo ʻakomi
- Ke hoʻouka nei i ka noi
- Hoʻāʻo
Nā Mea Hana
1. docker e holo i ka node a me Waves Explorer
Inā ʻaʻole ʻoe makemake e hoʻomaka i kahi node, hiki iā ʻoe ke lele i kēia kaʻina. Ma hope o nā mea a pau, aia kahi pūnaewele ho'āʻo a hoʻokolohua. Akā me ka ʻole o ka hoʻohana ʻana i kāu node ponoʻī, hiki ke hoʻomau i ke kaʻina hoʻāʻo.
- Pono mau ʻoe i nā moʻokāki hou me nā hōʻailona hoʻāʻo. Hoʻololi ka hoʻāʻo ʻana o ka ʻoihana pūnaewele i 10 WAVES i kēlā me kēia 10 mau minuke.
- ʻO ka awelika manawa poloka ma ka pūnaewele hoʻāʻo he 1 minuke, ma ka node - 15 kekona. ʻIke nui ʻia kēia i ka wā e koi ai ke kālepa i nā hōʻoia he nui.
- Hiki ke ho'opa'a 'ia ma nā node ho'ā'o lehulehu.
- Loaʻa ʻole paha lākou no kekahi manawa ma muli o ka mālama ʻana.
Mai kēia manawa e manaʻo wau e hana ana ʻoe me kāu node ponoʻī.
2. Mea Paahana Papa Heenalu
- Hoʻoiho a hoʻouka iā Node.js me ka hoʻohana ʻana i ka ppa, homebrew a i ʻole exe ma aneʻi: .
- E hoʻouka i ka Surfboard, kahi mea hana e hiki ai iā ʻoe ke holo i nā hoʻokolohua ma kahi node e kū nei.
npm install -g @waves/surfboard
3. Pākuʻi Visual Studio Code
He koho kēia ʻanuʻu inā ʻaʻole ʻoe he punahele o IDE a makemake i nā mea hoʻoponopono kikokikona. ʻO nā mea hana pono a pau he mau laina kauoha. Inā ʻoe e hoʻohana i ka vim, e hoʻolohe i ka plugin .
Hoʻoiho a hoʻokomo i ka Visual Studio Code:
E wehe i ka VS Code a hoʻokomo i ka plugin waves-ride:
ʻO ka hoʻonui pūnaewele Waves Keeper:
Hanaʻia!
E hoʻomaka i ka node a me Waves Explorer
1. E hoʻomaka i ka node:
docker run -d -p 6869:6869 wavesplatform/waves-private-node
E hōʻoia i ka hoʻomaka ʻana o ka node ma o ka REST API ma :
Swagger REST API no ka node
2. E hoʻomaka i kahi laʻana o Waves Explorer:
docker run -d -e API_NODE_URL=http://localhost:6869 -e NODE_LIST=http://localhost:6869 -p 3000:8080 wavesplatform/explorer
E wehe i kahi polokalamu kele a hele i . E ʻike ʻoe i ka wikiwiki o ke kūkulu ʻia ʻana o kahi kaapuni node kūloko.
Hōʻike ʻo Waves Explorer i kahi laʻana node kūloko
Hoʻolālā RIDE a me ka mea hana papa heʻe nalu
E hana i kahi papa kuhikuhi hakahaka a holo i ke kauoha i loko
surfboard init
Hoʻomaka ke kauoha i kahi papa kuhikuhi me ka hoʻolālā papahana, nā noi a me nā hoʻāʻo "hello world". Inā wehe ʻoe i kēia waihona me VS Code, e ʻike ʻoe:
Surfboard.config.json
- Ma lalo o ka waihona ./ride/ e ʻike ʻoe i kahi faila wallet.ride - ka papa kuhikuhi kahi i loaʻa ai ka code dApp. E nānā pōkole mākou i nā dApps i ka poloka aʻe.
- Ma lalo o ka waihona ./test/ e ʻike ʻoe i kahi faila *.js. Mālama ʻia nā hoʻāʻo ma ʻaneʻi.
- ./surfboard.config.json – faila hoʻonohonoho no ka holo ʻana i nā hoʻokolohua.
He ʻāpana koʻikoʻi ʻo Envs. Hoʻonohonoho ʻia kēlā me kēia kaiapuni e like me kēia:
- REST API hope o ka node e hoʻohana ʻia e hoʻomaka i ka dApp a me CHAIN_ID o ka pūnaewele.
- ʻO kahi ʻōlelo huna no kahi moʻokāki me nā hōʻailona e lilo i kumu o kāu mau hōʻailona hōʻike.
E like me kāu e ʻike ai, kākoʻo ʻo surfboard.config.json i nā kaiapuni he nui. ʻO ka paʻamau ka kaiapuni kūloko (ʻo ke kī defaultEnv kahi hoʻololi hoʻololi).
Palapala hoʻopalekana-demo
ʻAʻole kēia ʻāpana i ka ʻōlelo RIDE. Akā, e nānā i ka noi a mākou e kau ai a hoʻāʻo e hoʻomaopopo maikaʻi i ka mea e hana nei i ka blockchain.
E nānā kākou i kahi noi Wallet-demo maʻalahi. Hiki i kekahi ke hoʻouna i nā hōʻailona i kahi helu dApp. Hiki iā ʻoe ke unuhi wale i kāu WAVES. Loaʻa nā hana ʻelua @Callable ma o InvokeScriptTransaction:

Ma ke ola holoʻokoʻa o dApp, e mālama ʻia ke ʻano (ka helu helu → ka nui):

Kākoʻo ka VSCode plugin i ka hoʻopili mau ʻana i ka wā e hoʻoponopono ai i kahi faila. No laila, hiki iā ʻoe ke nānā mau i nā hewa ma ka pā PROBLEMS.
Inā makemake ʻoe e hoʻohana i kahi hoʻoponopono kikokikona ʻē aʻe i ka wā e hōʻuluʻulu ai i ka faila, e hoʻohana
surfboard compile ride/wallet.ride
E hoʻopuka kēia i kahi pūʻulu o base64 i hōʻuluʻulu ʻia RIDE code.
Hōʻoia i ka palapala no 'wallet.ride'
E nana kakou . Hoʻohana ʻia e kā JavaScript's Mocha framework. Aia kahi hana "Ma mua" a ʻekolu mau ho'āʻo:
- "Ma mua" e hoʻolilo i nā moʻolelo he nui ma o MassTransferTransaction, e hōʻuluʻulu i ka palapala a kau i ka blockchain.
- "Hiki ke waiho" e hoʻouna i kahi InvokeScriptTransaction i ka pūnaewele, e hoʻāla ana i ka waihona () hana no kēlā me kēia o nā moʻolelo ʻelua.
- "ʻAʻole hiki ke hoʻihoʻi hou aku ma mua o ka waiho ʻia" ʻaʻole hiki i kekahi ke ʻaihue i nā hōʻailona o nā poʻe ʻē aʻe.
- "Hiki ke waiho" i nā hōʻoia e hana pololei ʻia nā withdrawals.
Holo i nā hoʻāʻo mai ka Surfboard a hoʻopaʻa i nā hopena ma Waves Explorer
To run the test, run
surfboard test
Inā loaʻa iā ʻoe nā palapala he nui (no ka laʻana, pono ʻoe i kahi palapala hoʻoili ʻokoʻa), hiki iā ʻoe ke holo
surfboard test my-scenario.js
E hōʻiliʻili ka papa heʻe nalu i nā faila hoʻāʻo ma ka waihona ./test/ a holo i ka palapala ma ka node i hoʻonohonoho ʻia ma surfboard.config.json. Ma hope o kekahi mau kekona e ʻike ʻoe i kahi mea penei:

Hooray! Ua hala nā ho'āʻo. I kēia manawa, e nānā kāua i ka mea e hoʻohana ai i ka Waves Explorer: e nānā i nā poloka a i ʻole e hoʻopili i kekahi o nā ʻōlelo ma luna i ka ʻimi (no ka laʻana, ka mea pili. wallet#. Ma laila ʻoe e ʻike ai i ka mōʻaukala kālepa, ke kūlana dApp, decompiled binary file.
Waves Explorer. He palapala noi i kau ʻia.
ʻO kekahi mau ʻōlelo aʻoaʻo papa heʻe nalu:
1. No ka hoʻāʻo ʻana i ka puni testnet, e hoʻohana:
surfboard test --env=testnet
2. Inā makemake ʻoe e ʻike i nā mana JSON o nā kālepa a pehea e hana ʻia ai e ka node, e holo i ka hoʻāʻo me -v (ʻo ia hoʻi 'verbose'):
surfboard test -v
Ke hoʻohana nei i nā polokalamu me Waves Keeper
1. Hoʻonohonoho i ka Waves Keeper e hana:
Hoʻonohonoho i ka Waves Keeper e hana me kahi node kūloko
2. Hoʻokomo i ka ʻōlelo huna me nā hōʻailona no ka pūnaewele? No ka maʻalahi, e hoʻohana i ka hua mua o kāu node: waves private node seed with waves tokens. Helu helu: 3M4qwDomRabJKLZxuXhwfqLApQkU592nWxF.
3. Hiki iā ʻoe ke holo i kahi palapala ʻaoʻao ʻaoʻao ʻole me ka hoʻohana ʻana i ka npm. A i ʻole e hele i ka mea i loaʻa:
4. E hoʻokomo i ka helu ʻeke kālā mai ka hoʻāʻo ʻana (i kaha ʻia ma luna) i loko o ka pahu kikokikona dApp address
5. E hoʻokomo i kahi kālā liʻiliʻi ma ke kahua "Deposit" a kaomi i ke pihi:
Noi ʻo Waves Keeper i ka ʻae e kau inoa i kahi InvokeScriptTransaction me ka uku o 10 WAVES.
6. E hōʻoia i ke kālepa:
Hana ʻia ke kālepa a hoʻolaha ʻia i ka pūnaewele. I kēia manawa hiki iā ʻoe ke ʻike i kāna ID
7. E nānā i ke kālepa me ka Waves Explorer. E hookomo i ka ID ma ke kahua huli
Nā hopena a me nā ʻike hou aku
Ua nānā mākou i nā mea hana no ka hoʻomohala ʻana, ka hoʻāʻo ʻana, ka lawe ʻana a me ka hoʻohana ʻana i nā dApps maʻalahi ma ka Waves Platform:
- ʻōlelo RIDE
- VS Code Lunahooponopono
- Waves Explorer
- Papa heʻe nalu
- Kahu Nalu
Nā loulou no ka poʻe makemake e hoʻomau i ke aʻo ʻana i ka RIDE:
E hoʻomau i ka luʻu ʻana i ke kumuhana RIDE a hana i kāu dApp mua!
