Very tiny (53 lines including whitespace) library to build ArQL for queries for Arweave https://www.github.com/ArweaveTeam/arweave-js
Packaged up with https://github.com/pikapkg/pack, for web, node, typescript and even deno!
For fun, it's published on the on the arweave blockchain itself :)
npm install https://kybjhezuyftg.arweave.net/ITTPLYoxidZzAJP50FQ03QJUSkkh9iKHcmMcLZOvqtQ
- PROS: exact dependency pinning, immutable blockchain so package can't be removed or replaced with something malicious. (although npm lockfiles and exact versions will take of this too)
- CONS: not exactly easy to remember install line :D manual upgrades
This works because npm can install a .tgz file from any url, so it was just a matter of running pika build, tar'ing the pkg/ folder it produces, and uploading to arweave.
Also available on npm: npm install arql-ops
import { and, or, equals } from 'arql-ops';
const myQuery = and(
equals('from', 'awalletaddressXyz'),
equals('App-Name', 'super-app'),
or(
equals('someTag', '4'),
equals('someTag', '5'),
equals('someTag', '6')
)
);
const results = await arweave.arql(myQuery);With spread operators:
const myQuery = and(
equals('App-Name', 'my-app'),
equals('myFooTag', 'bar'),
or(
...listOfPossibleSomeTagValues.map(val => equals('someTag', val))
)
);
const results = await arweave.arql(myQuery);and() and or() will take any number of arguments and produce the correct Json of nested expressions:
const query = and(
equals('my-super-tag', '1'),
or(
equals('my-color-tag', 'red'),
equals('my-color-tag', 'blue'),
equals('my-color-tag', 'purple'),
equals('my-color-tag', 'orange'),
equals('my-color-tag', 'white'),
equals('my-color-tag', 'black'),
)
);This will produce a query that matches TXs with the tag 'my-super-tag'=1 , AND any of the color values that match 'my-color-tag'
Output Json:

"op": "equals",

"expr2": "1"
},
