aoNote SDK

Installation

Use npm due to its imcompatibility with yarn.

npm i aonote

aoNote SDK goes beyond Atomic Notes, streamlining Arweave/AO development with elegant syntax enhancements and seamless message piping for an enjoyable coding experience.

import { AR, AO, Profile, Notebook, Note } from "aonote"

AR

AR handles operations on the base Arweave Storage layer as well as wallet connections.

Instantiate

const ar = new AR()

host, port, and protocol can be set to access a specific gateway rather than https://arweave.net.

const ar = new AR({ host: "localhost", port: 4000, protocol: "http" })

In case of local gateways, you can only set port and the rest will be automatically figured out.

const ar = new AR({ port: 4000 })

Set or Generate Wallet

You can initialize AR with a wallet JWK or ArConnect.

const ar = await new AR().init(jwk || arweaveWallet)

Or you can generate a new wallet. In case of ArLocal, you can mint AR at the same time.

const { jwk, addr, pub, balance } = await ar.gen("100") // mint 100 AR

Once a wallet is set in one of these 3 ways, you cannot use the instance with another wallet unless you re-initialize it with another wallet. This is to prevent executing transactions with the wrong wallet when the browser connected active address has been changed unknowingly.

You can go on without calling init or gen, in this case, AR generates a random wallet when needed, and also using different wallets will be allowed. This is useful, if you are only calling dryrun with AO, since AO requires a signature for dryrun too, but you don't want to bother the user by triggering the browser extension wallet for read only calls.

Once a wallet is set, ar.jwk and ar.addr will be available.

Token Related Methods

toAddr

Convert a jwk to the corresponding address.

const addr = await ar.toAddr(jwk)

mine

Mine pending blocks (only for arlocal).

await ar.mine()

balance | toAR | toWinston

Get the current balance of the specified address in AR. addr will be ar.addr if omitted.

const balance_AR = await ar.balance() // get own balance
const balance_Winston = ar.toWinston(balance_AR)
const balance_AR2 = ar.toAR(balance_Winston)
const balance_AR3 = await ar.balance(addr) // specify wallet address

transfer

Transfer AR token. amount is in AR, not in winston for simplicity.

const { id } = await ar.transfer(amount, to)

You can set a jwk to the 3rd parameter as a sender, otherwise the sender is ar.jwk.

const { id } = await ar.transfer(amount, to, jwk)

For most write functions, jwk can be specified as the last parameter or a field like { data, tags, jwk }.

checkWallet

checkWallet is mostly used internally, but it returns this.jwk if a wallet has been assigned with init, or else it generates a random wallet to use. The following pattern is used in many places. With this pattern, if a wallet is set with init and the jwk the user is passing is different, checkWallet produces an error to prevent the wrong wallet. If no wallet has been set with init or gen and the jwk is not passed, it generates and returns a random wallet.

some_class_method({ jwk }){
  let err = null
  ;({ err, jwk } = await ar.checkWallet({ jwk }))
  if(!err){
    // do domething with the jwk
  }
}

Storage Related Methods

post

Post a data to Arweave.

const { err, id } = await ar.post({ data, tags })

tags are not an Array but a hash map Object for brevity.

const tags = { "Content-Type": "text/markdown", Type: "blog-post" }

If you must use the same name for multiple tags, the value can be an Array.

const tags = { Name: [ "name-tag-1", "name-tag-2" ] }

tx

Get a transaction.

const tx = await ar.tx(txid)

data

Get a data.

const data = await ar.data(txid, true) // true if string

bundle

Bundle ANS-104 dataitems.

const { err, id } = await ar.bundle(dataitems)

dataitems are [ [ data, tags ], [ data, tags ], [ data, tags ] ].

const { err, id } = await ar.bundle([
  [ "this is text", { "Content-Type": "text/plain" }],
  [ "# this is markdown", { "Content-Type": "text/markdown" }],
  [ png_image, { "Content-Type": "image/png" }]
])

AO

Instantiate

You can initialize AO in the same way as AR.

const ao = await new AO().init(arweaveWallet || jwk)

If you need to pass AR settings, use ar. ao.ar will be automatically available.

const ao = await new AO({ ar: { port: 4000 }}).init(arweaveWallet || jwk)
const addr = ao.ar.addr
await ao.ar.post({ data, tags })

AO Core Functions

deploy

Spawn a process, get a Lua source, and eval the script. src is an Arweave txid of the Lua script.

const { err, res, pid } = await ao.deploy({ data, tags, src, fills })

fills replace the Lua source script from src.

local replace_me = '<REPLACE_ME>'
local replace_me_again = '<REPLACE_ME_AGAIN>'
local replace_me_with_hello_again = '<REPLACE_ME>'
const fills = { REPLACE_ME: "hello", REPLACE_ME_AGAIN: "world" }

This will end up in the following lua script.

local replace_me = 'hello'
local replace_me_again = 'world'
local replace_me_with_hello_again = 'hello'

In case you have multiple scripts, use loads and pass src and fills respectively.

await ao.deploy({ tags, loads: [ { src, fills }, { src: src2, fills: fills2 } ] })

msg

Send a message.

const { err, mid, res, out } = await ao.msg({ 
  data, action, tags, check, checkData, get
})

check determins if the message call is successful by checking through Tags in Messages in res.

const check = { "Status" : "Success" } // succeeds if Status tag is "Success"
const check2 = { "Status" : true } // succeeds if Status tag exists

checkData checks Data field instead of Tags.

const checkData = "Success"  // succeeds if Data field is "Success"
const checkData2 = true // succeeds if Data field exists

get will return specified data via out.

const get = "ID" // returns the value of "ID" tag
const get2 = { name: "Profile", json: true } // "Profile" tag with JSON.parse()
const get3 = { data: true, json: true } // returns Data field with JSON.parse()

dry

Dryrun a message without writing to Arweave.

const { err, res, out } = await ao.dry({ 
  data, action, tags, check, checkData, get
})

asgn

Assign an existing message to a process.

const { err, mid, res, out } = await ao.asgn({ pid, mid, check, checkData, get })

load

Get a Lua source script from Arweave and eval it on a process.

const { err, res, mid } = await ao.load({ src, fills, pid })

eval

Eval a Lua script on a process.

const { err, res, mid } = await ao.eval({ pid, data })

spwn

Spawn a process. module and scheduler are auto-set if omitted.

const { err, res, pid } = await ao.spwn({ module, scheduler, tags, data })

aoconnect Functions

The original aoconnect functions message | spawn | result | assign | dryrun are also available.
createDataItemSigner is available as toSigner.

const signer = ao.toSigner(jwk)
const process = await ao.spawn({ module, scheduler, signer, tags, data })
const message = await ao.message({ process, signer, tags, data })
const result = await ao.result({ process, message })

Advanced Functions

postModule

data should be wasm binary. overwrite to replace the default module set to the AO instance.

const { err, id: module } = await ao.postModule({ data, jwk, tags, overwrite })

postScheduler

This will post Scheduler-Location with the jwk address as the returning scheduler.

const { err, scheduler } = await ao.postScheduler({ url, jwk, tags, overwrite })

wait

wait untill the process becomes available after spwn. This is mostly used internally with deploy.

const { err } = await ao.wait({ pid })

Function Piping

Most functions return in the format of { err, res, out, pid, mid, id }, and these function can be chained with pipe, which makes executing multiple messages a breeze.

For example, following is how deploy uses pipe internally. The execusion will be immediately aborted if any of the functions in fns produces an error.

let fns = [
  {
    fn: "spwn",
    args: { module, scheduler, tags, data },
    then: { "args.pid": "pid" },
   },
   { fn: "wait", then: { "args.pid": "pid" } },
   { fn: "load", args: { src, fills }, then: { "args.pid": "pid" } }
]
const { err, res, out, pid } = await this.pipe({ jwk, fns })

bind

If the function comes from other instances rather than AO, use bind.

const fns = [{ fn: "post", bind: this.ar, args: { data, tags }}]

then

You can pass values between functions with then. For instance, passing the result from the previous functions to the next function's arguments is a common operation.

const fns = [
  { fn: "post", bind: ao.ar, args: { data, tags }, then: ({ id, args, out })=>{
    args.tags.TxId = id // adding TxId tag to `msg` args
	out.txid = id // `out` will be returned at last with `pipe`
  }},
  { fn: "msg", args: { pid, tags }},
]
const { out: { txid } } = await ao.pipe({ fns, jwk })

If then returns a value, pipe will immediately return with that single value. You can also use err to abort pipe with an error.

const fns = [
  { fn: "msg", args: { pid, tags }, then: ({ inp })=>{
     if(inp.done) return inp.val
  }},
  { fn: "msg", args: { pid, tags }, err: ({ inp })=>{
     if(!inp.done) return "something went wrong"
  }},
]
const val = await ao.pipe({ jwk, fns })

then has many useful parameters.

  • res : res from the previous result
  • args : args for the next function
  • out : out the final out result from the pipe sequence
  • inp : out from the previous result
  • _ : if values are assigned to the _ fields, pipe returns them as top-level fields in the end
  • pid : pid will be passed if any previous functions returns pid ( e.g. deploy )
  • mid : mid will be passed if any previous functions returns mid ( e.g. msg )
  • id : id will be passed if any previous functions returns id ( e.g. post )

then can be a simplified hashmap object.

let fns = [
  {
    fn: "msg",
    args: { tags },
    then: { "args.mid": "mid", "out.key": "inp.a", "_.val": "inp.b" },
   }, 
   { fn: "some_func", args: {} } // args.mid will be set from the previous `then`
]
const { out: { key }, val } = await ao.pipe({ jwk, fns })

cb

cb can report the current progress of pipe after every function execution.

await ao.pipe({ jwk, fns, cb: ({ i, fns, inp })=>{
  console.log(`${i} / ${fns.length} functions executed`)
}})
