retrieve schema from Segment dashboard

gistfile1.txt

/*
When logged into Segment dashboard and looking at event schema for source, open dev tools and go to Apollo Dev Tools (chrome extension). 

In GraphiQL run this query:
query getSourceData($workspaceSlug: String!, $sourceSlug: String!) {
  me {
    isAdmin
    id
    __typename
  }
  workspace(slug: $workspaceSlug) {

    source(slug: $sourceSlug) {
      id
      warehouseSchema{
        collection
        properties{
          key
          enabled
          
        }
      }
     
    }
  }
}

where variables = 
{
  "workspaceSlug": "your-workspace-slug",
  "sourceSlug": "the-source-name" // eg 'javascript'
}


From the results, store data.workspace.source.warehouseSchema in a variable in the Chrome Console

Then run this (where d is the var you kept the data in)
*/

copy(
  d
    .map(r => r.properties.map(p => [r.collection, p.key]))
    .reduce((prev, acc) => [...(prev || []), ...acc], [])
    .map(a => a.join("\t"))
    .join("\n")
);

// copies a TSV format where event name is first col and prop name is second
