NCBI-written audit to test for meta with name="ncbi_app"

ncbi_app-audit.js

"use strict";

const Audit = require("lighthouse").Audit;


class NCBIAppAudit extends Audit {
  static get meta() {
    return {
      id: "ncbi_app-audit",
      title: 'meta name="ncbi_app" is set',
      failureTitle: 'No meta name="ncbi_app" is set',
      description:
        '<meta name="ncbi_app" must be set to properly ping to applog',

      // The name of the custom gatherer class that provides input to this audit.
      requiredArtifacts: ["NCBIAppMeta"]
    };
  }

  static audit(artifacts) {
    const ret = artifacts.NCBIAppMeta;
    const score = ret.name && ret.content;
    return {
      rawValue: score,
      score: Number(score)
    };
  }
}

module.exports = NCBIAppAudit;

so here it might look like const score = ret.content && ret.content.length > 3
