Exposes immutable useful functions from Lodash to jsonLogic
Unsupported GraphQL keys: ==
, ===
, !=
, !==
, >
, >=
, <
, <=
, !!
, !
, %
, +
, *
, -
, /
Use any of _eq
, _gt
, _gte
, _lt
, _lte
etc from Lodash methods
# Yarn
$ yarn add json-logic-js-graphql
# NPM
$ npm install json-logic-js-graphql --save
import { jsonLogic } from 'json-logic-js-graphql'
const rules = {
_eq: [{ var: 'foo' }, { var: 'bar' }],
}
const data = { foo: 'bar', bar: 'bar' }
jsonLogic.apply(rules, data)
jsonLogic's equal operator is "==="
so it can't be used as a GraphQL key.
We expose the eq
lodash method as _eq
to jsonLogic.
mutation {
updateResource(
id: "609ce9dbec9fb60004087784"
logic: { _eq: [{ var: "foo" }, "bar"] }
) {
id
}
}
All Lodash methods exposed with the
_
namespace to avoid overwriting the default jsonLogic's functionality
_gteDate
, _gtDate
, _lteDate
, _ltDate
, _eqDate
, _getDate
example:
const rules = {
_gteDate: [
[{ var: 'from' }, { var: 'to' }],
[364, 'days'],
],
}
const data = { from: '2020-10-01', to: '2021-10-01' }
jsonLogic.apply(rules, data)
