ArDB

The best way to interact with the weave, without having to write any GQL and trying to remember param names!

ArDB is well typed and with the basic functions anyone will need to run and execute any request.

Plus, coming soon, we are planing to release an easy way to add or update data to Arwaeve right from ArDB!

Let's get coding!

First you'll need to add ardb to your project:

yarn add ardb

Import it into your project file:

import ArDB from 'ardb';
const ardb = new ArDB(arweaveInstance, logLevel? = LOG.ARWEAVE); // logLevel is optional and respects Arweave's logging by default.

Initialisation

// arweave is Arweave Client instance
const ardb = new ArDB(arweave);

And now we are ready to play with it!

Examples:

// Get a single transaction
const tx = await ardb.search('transaction').id('A235HBk5p4nEWfjBEGsAo56kYsmq7mCCyc5UZq5sgjY').findOne();

// Get an array of transactions, in this case it will be of length 1 since
// we asked to find only 1.
const txs = await ardb.search('transactions').appName('SmartWeaveAction').findOne();

// This is the same as doing:
const txs = await ardb.search('transactions').tag('App-Name', 'SmartWeaveAction').limit(1).find();

// Search for multiple transactions
const txs = await ardb.search('transactions').from('BPr7vrFduuQqqVMu_tftxsScTKUq9ke0rx4q5C9ieQU').find();

// You can then keep going and searching for more by doing:
const newTxs = await ardb.next();

// Or you could get everything at once by doing:
const txs = await ardb.search('blocks').id('BkJ_h-GGIwfek-cJd-RaJrOXezAc0PmklItzzCLIF_aSk36FEjpOBuBDS27D2K_T').findAll();

API

search(type: 'transaction' | 'transactions' | 'block' | 'blocks' = 'transactions')

• Every time we want to do a new request, que have to call search() before any other method.
• Default is transactions.

id(id: string)
ids(ids: string[])

• Get transactions and blocks by ids.
• If the search is of type block or transaction, and you set ids(['TXID']), the first ID in the array will be selected as the search value.

appName(name: string)

• Search by the default App-Name tag and set it's value to name.
• Same as using: tag('App-Name', name) or find({tags: [{name: 'App-Name', values: [name]}]}) but much shorter.

type(type: string)

• Search by the default Content-Type tag and set it's value to type.

tags(tags: {name: string, values: string|string[]})

• Search by custom tags, example: tags([{name: 'app', values: ['myval']}, {name: 'date', values: ['yesterday', 'today']}]).

tag(name: string, values: string|string[])

• Do a search with a single tag, example: tag('app', 'myval') or tag('date', ['yesterday', 'today']).

from(owners: string|string[])

• Search by using the deployer's wallet address. Can be either a string or an array of owners (string).

to(recipients: string|string[])

• Search by using one (string), or a list (array of strings), of recipients.

min(min: number)
max(max: number)

• Find transactions within a given block height range.

only(fields: string|string[])

• Only return the specified return fields from your GQL query.

exclude(fields: string|string[])

• Excludes the specified return fields from your GQL query.

limit(limit: number)

• Limit the search to the limit. Default is 10.
• Note: Arweave's GQL doesn't return a list bigger than 100 items at once.

sort(sort: 'HEIGHT_DESC' | 'HEIGHT_ASC')

• Sort the results by either desc or asc based on the block height.
• Default is HEIGHT_DESC.

cursor(cursor: string)

• If you need to retrieve transactions or blocks at a certain cursor, you can use the cursor() method to set it before doing the request.

Finding

After we complete our request with the previous methods, we can go ahead and find the items.

findOne(options: GlobalOptions = {})

• Returns one item. For transactions and blocks it set the limit to 1 automatically, even if a limit() is set.

  find(options: GlobalOptions = {})

• Returns an array of items based on their limit(), if not set, limit is at the default 10.

  findAll(options: GlobalOptions = {})

• Returns all the items, no mather the limit.

  next()

• Returns the next batch of items. If used after find() it returns one item. Else, it returns an array of items.

  run(query: string)

• Manually run a GQL query string.

  runAll(query: string)

• Manually run and return all from a GQL query string.

  Type declarations

  
  export interface IBlock {
  id?: string;
