// Percy manual build finalization for Circle 2.0 and other parallel CI workflows.

//
// STEP 0: make sure you are running percy-client >= 2.2.0.
//

//
// STEP 1: opt in to manual parallel handling by setting PERCY_PARALLEL_TOTAL=-1
//         in your environment. Note that it is -1, not 1.
//

//
// STEP 2: create a file named `percy-finalize.js` containing:
//

process.env['PERCY_PARALLEL_TOTAL'] = '-1';

let Environment = require('percy-client/dist/environment');
let PercyClient = require('percy-client');
var environment = new Environment(process.env);

if (!environment.parallelNonce || !environment.parallelTotalShards) {
  console.warn('[percy][ERROR] PERCY_PARALLEL_NONCE and PERCY_PARALLEL_TOTAL must be set.')
}

let percyClient = new PercyClient({token: process.env.PERCY_TOKEN});
let currentBuildPromise = percyClient.createBuild();
currentBuildPromise.then((currentBuild) => {
  console.log(`[percy] Finalizing all parallel shards for build: ${currentBuild.body.data.id}`);
  percyClient.finalizeBuild(currentBuild.body.data.id, {allShards: true});
});
