Blog with a View: Update

Apparently, Hashnode has updated its GraphQL API - so much so that the view in my old post - Blog with a View - is no longer accurate. It will still run, but it won’t return any data.

Fortunately, the fix is pretty simple. Use this view instead of the one mentioned in the post, and it should still work:

create or replace view blog_v
as
with json as
  (
  select
    apex_web_service.make_rest_request
      (
       p_url=> 'https://gql.hashnode.com'
      ,p_http_method => 'POST'
      ,p_body => '{ "query" : "query Publication '
      || '          { publication(host: \"spendolini.blog\") '
      || '            { id title posts(first: 10) '
      || '              { edges '
      || '                { node '
      || '                  { id title subtitle url slug brief publishedAt reactionCount responseCount content { markdown } coverImage { url } '
      || '                  } '
      || '                } totalDocuments '
      || '              } '
      || '            } '
      || '          }" '
      || '        }'
      ) as val
  from
    dual
  )
select
   t.id
  ,to_timestamp(t.date_added, 'YYYY-MM-DD"T"HH24:MI:SS.FF"Z"') as date_added
  ,t.slug
  ,'https://spendolini.blog/' || t.slug as url
  ,t.title
  ,t.brief
  ,t.cover_image
  ,t.popularity
  ,t.total_reactions
  ,t.content
from
  json,
  json_table
    (
      json.val
     ,'$.data.publication.posts.edges.node[*]'
    columns
      (
       id              varchar2(1000) path '$.id'
      ,slug            varchar2(1000) path '$.slug'
      ,title           varchar2(1000) path '$.title'
      ,brief           varchar2(1000) path '$.brief'
      ,cover_image     varchar2(1000) path '$.coverImage.url'
      ,date_added      varchar2(1000) path '$.publishedAt'
      ,popularity      number         path '$.popularity'
      ,total_reactions number         path '$.reactionCount'
      ,content         clob           path '$.content.markdown'
      )
    ) as t;

There’s also a new GraphQL Playground for Hashnode’s APIs that’s worth checking out.
