@gql-conquest/query-selector
Query your HTML using GraphQL. Replaces document.querySelector.
Installation
npm install @gql-conquest/query-selector
Ensure you have graphql
installed as a peer dependency:
npm install graphql
You will also need graphql-tag
to tag your query:
npm install graphql-tag
Usage
querySelector
Pass the tagged gql query and the root element.
Fetch all p
tags from a root element.
import querySelector from '@gql-conquest/query-selector'
import gql from 'graphql-tag'
const root = document.querySelector('#root')
const result = querySelector(gql`
{
p: all(s: "p")
}`, root)
Fetch all spans and italics under headings under section and all spans under section.
const result = querySelector(gql`
{
section: one(s: "section") {
headings: all(s: "h1, h2, h3, h4, h5, h6") {
spans: one(s: "span")
italics: one(s: "i")
}
spans: all(s: "span")
}
}`, root)
// one span from each heading
assert.deepStrictEqual(result.headings.spans, [<span></span>, <span></span>])
NOTE: Nesting all
fields will cause unwanted behavior. Do not do the following.
This will most likely lead to problems as spans
is an all
field nested under headings
, which is also an all
field:
const result = querySelector(gql`
{
section: one(s: "section") {
headings: all(s: "h1, h2, h3, h4, h5, h6") {
spans: all(s: "span")
italics: one(s: "i")
}
spans: all(s: "span")
}
}`, root)
