AEM Headless Client for JavaScript

See aem-headless-client-java for the Java variant of this client and aem-headless-client-nodejs for the server-side Node.js variant.

Installation

$ npm install @adobe/aem-headless-client-js

Usage

Create AEMHeadless client

const AEMHeadless = require('@adobe/aem-headless-client-js');

Configure SDK with Host and Auth data (if needed)

const aemHeadlessClient = new AEMHeadless({
    serviceURL: '<aem_host>',
    endpoint: '<graphql_endpoint>',
    auth: '<aem_token>' || ['<aem_user>', '<aem_pass>'],
    headers: {'<headername>': '<headervalue>', ...}
})
// Eg:
const aemHeadlessClient = new AEMHeadless({
    serviceURL: AEM_HOST_URI,
    endpoint: 'content/graphql/endpoint.gql',
    auth: [AEM_USER, AEM_PASS],
    headers: {'customerheadername': 'customerheadervalue'}
})

Use AEMHeadless client

Promise syntax:

aemHeadlessClient.runQuery(queryString)
  .then(data => console.log(data))
  .catch(e => console.error(e.toJSON()))

aemHeadlessClient.listPersistedQueries()
   .then(data => console.log(data))
   .catch(e => console.error(e.toJSON()))

aemHeadlessClient.persistQuery(queryString, 'wknd/persist-query-name')
   .then(data => console.log(data))
   .catch(e => console.error(e.toJSON()))

aemHeadlessClient.runPersistedQuery('wknd/persist-query-name')
   .then(data => console.log(data))
   .catch(e => console.error(e.toJSON()))

aemHeadlessClient.runPersistedQuery('wknd/persist-query-name-with-variables', { name: 'John Doe'})
    .then(data => console.log(data))
    .catch(e => console.error(e.toJSON()))

Within async/await:

(async () => {
    let postData
    try {
        postData = await aemHeadlessClient.runQuery(queryString)
    } catch (e) {
        console.error(e.toJSON())
    }
    
    let list
    try {
        list = await aemHeadlessClient.listPersistedQueries()
    } catch (e) {
        console.error(e.toJSON())
    }

    try {
        await aemHeadlessClient.persistQuery(queryString, 'wknd/persist-query-name')
    } catch (e) {
        console.error(e.toJSON())
    }
    
    let getData
    try {
        getData = await aemHeadlessClient.runPersistedQuery('wknd/persist-query-name')
    } catch (e) {
        console.error(e.toJSON())
    }
})()    

Pagination:

(async () => {
    const model = 'article'
    const fields = `{
        title
        _path
        authorFragment {
          firstName
          profilePicture {
            ...on ImageRef {
              _authorUrl
            }
          }
        }
      }`
    
    // Loop all pages (default Cursor based)
    const cursorQueryAll = await aemHeadlessClient.runPaginatedQuery(model, fields, { pageSize: 3 })
    for await (let value of cursorQueryAll) {
        console.log('cursorQueryAll', value)
    }
    // Manually get next page (default pageSize = 10)
    const cursorQuery = await aemHeadlessClient.runPaginatedQuery(model, fields)
    while (true) {
        const { done, value } = await cursorQuery.next();
        if (done) break
        console.log('cursorQuery', value)
    }
})()

Authorization

If auth param is a string, it's treated as a Bearer token

If auth param is an array, expected data is ['user', 'pass'] pair, and Basic Authorization will be used

If auth is not defined, Authorization header will not be set
