for loop in javascript - promise - .eslintrc for "for of"

the vast majority of cases map, forEach, find etc. can be used.

async function printFiles () {
  const files = await getFilePaths();

  await Promise.all(files.map(async (file) => {
    const contents = await fs.readFile(file, 'utf8')
    console.log(contents)
  }));
}

const inventory = [
  {name: 'apples', quantity: 2},
  {name: 'bananas', quantity: 0},
  {name: 'cherries', quantity: 5}
];

const result = inventory.find( ({ name }) => name === 'cherries' );

function getFirstMatching(array) {

    for (let item of array) {
        const result = heavyTransform(item);
        if (result) {
            return result;
        }
    }
}

Specifically this shuts down the whole no-restricted-syntax. If you want to cherry-pick, here is the current definition:

    'no-restricted-syntax': [ 
      'error', 
      { 
        selector: 'ForInStatement', 
        message: 'for..in loops iterate over the entire prototype chain, which is virtually never what you want. Use Object.{keys,values,entries}, and iterate over the resulting array.', 
      }, 
      /*
      { 
        selector: 'ForOfStatement', 
        message: 'iterators/generators require regenerator-runtime, which is too heavyweight for this guide to allow them. Separately, loops should be avoided in favor of array iterations.', 
      },
      */ 
      { 
        selector: 'LabeledStatement', 
        message: 'Labels are a form of GOTO; using them makes code confusing and hard to maintain and understand.', 
      }, 
      { 
        selector: 'WithStatement', 
        message: '`with` is disallowed in strict mode because it makes code impossible to predict and optimize.', 
      }, 
    ],

setup git account on mac with ssh - push to remote denied with other login

http://burnedpixel.com/blog/setting-up-git-and-github-on-your-mac/#generatenewkey “ SSH uses public-key cryptography to authenticate the remote computer and allow it to authenticate the user, if necessary. There are several ways to use SSH; one is to use automatically generated public-private key pairs to simply encrypt a network connection, and then use password authentication to log on.” An SSH key basically lets your computer uniquely identify itself when it connects to servers. If Github is aware of the key your computer is using, you won’t have to enter your Github username/password every time you connect. Check for pre-existing SSH keys on your computer Let’s see if your computer has one or more keys already installed: 1 2 # Point the terminal to the directory that would contain SSH keys for your user account. $ cd ~/.ssh If you get the response “No such file or directory”, skip to Generate a new SSH Key . Otherwise, you’ll need to backup...

fs.writeFile - permission issue on GCP (Google Cloud Run)

error on this: fs . writeFile ( fileName , pdfBytes , err => { if ( err ) { console . log ( err . message ) reject ( err . message ) } else resolve ( fileName ) }) #1 It looks like when deployed into Cloud Run it also requires the extra permission "Service Account Token Creator" to run getSignedUrl . Locally for some reason this role is not required. #2 Only the directory /tmp is writable in Cloud Run. So, change the default write location to write into this directory. However, you have to be aware of 2 things: Cloud Run is stateless, that means when a new instance is created, the container start from scratch, with an empty /tmp directory /tmp directory is an in-memory file system. The maximum allowed memory on Cloud Run is 2Gb, your app memory footprint included. In addition of your file and Airflow, not sure that you will have a lot of space. A final remark. Cloud Run is active only when it...
