TypeError: array.every is not a function

When running npm t i get the “TypeError: array.every is not a function” error. My code is very similar to yours.

var expect = require('chai').expect;
var dogBreedNames = require('./index');

describe('Dog breeds?', function () {

    describe('all', function () {

        it('should be a array of strings', function () {
            expect(dogBreedNames.all).to.satisfy(isArrayOfStrings);
            function isArrayOfStrings(array) {
                return array.every(function(item){
                    return typeof item === 'string'
                });
            }
        });

    });

});

and the index.js is the following:

var uniqueRandomArray = require('unique-random-array');
var dogBreedNames = require('./dogs.json');

var getRandomItem = uniqueRandomArray(dogBreedNames);

module.exports = {
    all: dogBreedNames,
    random: uniqueRandomArray(dogBreedNames)
};

function random(number) {
  if (number === undefined) {
    return getRandomItem();
  } else {
    var randomItems = [];
    for (var i = 0; i < number; i++) {
      randomItems.push(getRandomItem());
    }
    return randomItems;
  }
}

Solved it, there was the white space in travis.yml file for the script code, and I also needed to change the script attribute from -npm run test:single to

• npm run test-single

thanks, you were right. My json file for dogs was not in a array format. Thats what that happens if you stay up late 😃 I would like to take this opportunity to thank you. The course on egghead.io http://egghead.io/ is probably the best tutorial I have seen on front-end process.

Installing semantic-release globally didn’t put it local node_modules folder and update package.json file as devDependencie. I needed also to do a sudo npm install -D semantic-release

When I am at lesson 15 https://egghead.io/lessons/javascript-how-to-write-a-javascript-library-automatically-releasing-with-travisci#/tab-transcript and do git push I got a error message for the travis build. I don’t if it has to do with the error pointing to Build failures due to new sudo-enabled Precise and Trusty images https://www.traviscistatus.com/incidents/11hp8bhkrkn7 or that my build#1 in travis is generating an error in the travis.yml file itself. This is how the error looks like:

<>ERROR: An error occured while trying to parse your .travis.yml file. <> <>Please make sure that the file is valid YAML. <> <>http://lint.travis-ci.org http://lint.travis-ci.org/ can check your .travis.yml. <> <>The log message was: Build config file had a parse error: did not find expected ‘-’ indicator while parsing a block collection at line 13 column 3. and this is how my travis.yml looks like:

sudo: false language: node_js cache: directories: - node_modules notifications: email: false node_js:

• ‘4’ before_install:
• npm i -g npm@^2.0.0 before_script:
• npm prune script:
• npm run test:single after_success:
• npm run semantic-release branches: except:

- /^v\d+\.\d+\.\d+$/

Do you know what the issue could be about?

brgds Sohail once again, a really wonderful tutorial 😃

Ah, my guess is that dogBreedNames.all is not an array. Try adding some console.logs in there to get an idea of what you’re actually calling every on.

Thanks, I have been looking at that code 😃
