海外TECH	DEV Community	Building Full Stack Permanent Applications with Arweave, Smartweave, and Next.js	https://dev.to/dabit3/building-full-stack-applications-with-arweave-and-nextjs-28hg	Building Full Stack Permanent Applications with Arweave Smartweave and Next jsThe code for this tutorial can be found hereIn this tutorial you ll learn how to build full stack dapps on Arweave with Smarweave Warp and Next js Smartweave TLDRCode smart contracts in JS TS or RustExecute arbitrary amounts of compute without additional feesNever have to worry about gas optimizationsNo state bloatCan directly process rich content large filesWarp offers enhancements speed caching sdks The application we ll be building is a full stack blog meaning that you will have an open public and composable back end that can be transferred and reused anywhere not only in this app Unlike most blockchain applications working with large or arbitrary amounts of data Smartweave enables all of the state for this app to be stored directly on chain I think this is a good example as it s not too basic as to be boring but not too complex as to be confusing It shows how to do most of the basic things you ll need and want to understand in order to build more complex and sophisticated applications going forward About ArweaveArweave is a web protocol that allows developers to permanently store files like images videos and pdfs as well as single page web applications Arweave introduced the idea of the permaweb a permanent global community owned web that anyone can contribute to or get paid to maintain SmartweaveArweave also introduced SmartWeave a smart contract protocol that allows developers to build permanent applications on top of Arweave When you publish a Smartweave contract the program s source code and its initial state is stored in an Arweave transaction When a user writes an update to a SmartWeave program they write their inputs as a new Arweave transaction To calculate the state of the contract a SmartWeave client uses the contract source code to execute the history of inputs sequentially Invalid transactions are ignored In doing so SmartWeave pushes the responsibility of validating transactions onto the users WarpWarp is a protocol built on top of Arweave meant to facilitate a better DX UX for Smartweave application development Warp consists of main layers The Core Protocol layer is the implementation of the original SmartWeave protocol and is responsible for communication with the SmartWeave smart contracts deployed on ArweaveThe Caching layer is build on top of the Core Protocol layer and allows caching results of each of the Core Protocol modules separately This allows you to quickly retrieve data from contracts with a large number of state updates but also offers instant transactions and contracts availability and finality Extensions layer a CLI Debugging tools different logging implementations so called dry runs i e actions that allow to quickly verify the result of given contract interaction without writing anything on Arweave Getting startedNow that we know a little bit about the underlying technology let s start building PrerequisitesTo be successful in this tutorial you should have Node js or greater installed on your machine I recommend using either nvm or fnm to manage Node js versions Creating and configuring the projectTo get started let s first create the Next js application configure it and install the dependencies npx create next app full stack arweaveChange into the new directory and install the following dependencies npm install warp contracts react markdown uuid Configuring the Next js appOpen package json and add the following configuration type module Then update next config js to use ES Modules to export the nextConfig replace module exports nextConfig with this export default nextConfigThis will enable the Next js app to use ES Modules Next add the following to the gitignore file wallet jsontestwallet jsontransactionid jsNever push wallet information to any public place like GitHub In this tutorial we ll only be working with testnet but we ll have the code available for you to push to mainnet Just in case we re adding wallet json to gitignore Warp ContractsNext let s create and test out the smart contracts About Smartweave contractsSmartweave contracts work like this An initial state for the application is defined as a JSON object Some basic initial state might look something like this for a counter application that increments and decrements a number counter The logic of a Smartweave contract is written in a function named handle This function defines different actions that can be called on the contract which manipulate the state Actions are similar to functions in a normal smart contract or program Each action will update the state in some way A basic handler for a counter that uses the above state might look something like this export function handle state action if action input function increment state counter if action input function decrement state counter return state In this handler there are two actions increment or decrement The logic here is pretty straightforward To update the state of the contract we can call writeInteraction from the Warp SDK Here s a basic example of how this might look when calling this function on the server import WarpFactory from warp contracts const transactionId BAEIfkKvlPXLksENloAmpzrMezSPhwaujTNli import wallet from wallet json let warp WarpFactory forLocal const contract warp contract transactionId connect wallet await contract writeInteraction function decrement Then we can read the state at any time const contract warp contract transactionId connect const cachedValue await contract readState Writing the contractNow that we have a basic understanding of how contracts work let s start writing some code In the root of the project create a new folder named warp In this folder create a new file named contract js warp contract js export function handle state action address of the caller is available in action caller if action input function initialize state author action caller if action input function createPost amp amp action caller state author const posts state posts posts action input post id action input post state posts posts if action input function updatePost amp amp action caller state author const posts state posts const postToUpdate action input post posts postToUpdate id postToUpdate state posts posts if action input function deletePost amp amp action caller state author const posts state posts delete posts action input post id state posts posts return state This is the contract for our blogging app We have functions to create update and delete a post CRUD We also have an initialize function which adds a basic authorization rule that only allows the blog owner to call any of these functions by setting the contract deployer as the owner Next create a file in the warp directory named state json and add the following JSON posts author null Here we have an initial state of posts set to an empty object and author set to null We re done with our contract now let s write the code to deploy update and read the state of the contract Deploy update and readNext create a new file named configureWarpServer js in the warp directory import WarpFactory from warp contracts import fs from fs environment can be local testnet mainnet custom const environment process env WARPENV testnet let warpif environment testnet warp WarpFactory forTestnet else if environment mainnet warp WarpFactory forMainnet else throw Error environment not set properly async function configureWallet try if environment testnet for testing generate a temporary wallet try return JSON parse fs readFileSync testwallet json utf catch err const jwk await warp testing generateWallet fs writeFileSync testwallet json JSON stringify jwk return jwk else if environment mainnet for mainnet retrieve a local wallet return JSON parse fs readFileSync wallet json utf else throw Error Wallet not configured properly catch err throw Error Wallet not configured properly err export configureWallet warp In this file we re configuring warp server based on whether we re in a testing or mainnet production environment We then have a function that configures the wallet we ll be using to deploy the contract If we re testing we can just spin up a test wallet automatically using generateWallet If we re in production we have the option of importing a wallet locally Now that we have the ability to configure a wallet and a Warp server let s create the function for deploying the contracts Deploying the contractCreate a new file named deploy js in the warp directory with the following code import fs from fs import configureWallet warp from configureWarpServer js async function deploy const wallet await configureWallet const state fs readFileSync state json utf const contractsource fs readFileSync contract js utf const contractTxId await warp createContract deploy wallet initState state src contractsource fs writeFileSync transactionid js export const transactionId contractTxId const contract warp contract contractTxId connect wallet await contract writeInteraction function initialize const cachedValue await contract readState console log Contract state cachedValue console log contractTxId contractTxId deploy The deploy function will deploy the contract to Arweave and write the transaction id to the local file system Reading the stateNext let s create a file named read js with the following code import warp from configureWarpServer js import transactionId from transactionid js async function read const contract warp contract transactionId connect const cachedValue await contract readState console log Contract state JSON stringify cachedValue read Writing an updateThe last function we ll write is for creating a new post In the warp directory create a new file named createPost js with the following code import warp configureWallet from configureWarpServer js import transactionId from transactionid js import v as uuid from uuid async function createPost let wallet await configureWallet const contract warp contract transactionId connect wallet await contract writeInteraction function createPost post title Hi from first post content This is my first post id uuid createPost Testing it outNow we can test everything out To deploy the contract run the following command from the warp directory node deployThis should deploy the contract to testnet Once the contract has been deployed you can use the Sonar block explorer to view the contract and the current state of it The contract transaction ID will be available in transactionid js Be sure to switch to testnet to view the contract from this deployment Next let s read the current state node readThe returned state of the contract should look something like this state posts author YzqAM VDCqFZEkiZBY bSxHohFSvjOCWnY validity CmMGSlrGNvvCCfldtiUzaZnQ bFWYoEhNCVe true errorMessages Now let s create a post node createPostNow when we read the updated state we should see the new post in the updated state node read Building out the web appNow that we understand how to deploy and test out a Smartweave contract with Warp let s build out a front end application that will interact with it and use it Since the application we re building is a blog we ll need to create two basic views A view to see the posts created by the user A view to allow users to create posts We ll also need a file to hold a function we ll be using to configure warp for the client similar to how we configured warp for the server previously Create a new file named configureWarpClient js in the root of the app and add the following code import WarpFactory from warp contracts import transactionId from transactionid import wallet from testwallet environment can be local testnet mainnet custom const environment process env NEXT PUBLIC WARPENV testnet let warplet contractasync function getContract if environment testnet warp WarpFactory forTestnet contract warp contract transactionId connect wallet else if environment mainnet warp WarpFactory forMainnet contract warp contract transactionId connect else throw new Error Environment configured improperly return contract export getContract Creating a postNext in the pages directory create a new file named create post js and add the following code import useState from react import getContract from configureWarpClient import v as uuid from uuid import useRouter from next router export default function createPostComponent const post updatePost useState title content const router useRouter async function createPost
