Node.js map returning result between quotes and brackets in Slack window

I am building a Slack app that has a slash command for displaying data from the database using pg-promise module like this:

select: () =>
    rep.map(sql.select, null, row => {
        return 'User ' + row.username + ' is ' + row.status;
    }),

Like this, an array of rows is returned, but the result is always like:

["User username1 is status1", "User username2 is status2", ...]

I need it to be displayed in a list, without these quotes and brackets.

User username1 is status1
User username2 is status2
...

I've tried to replace using regex, but it doesn't work.

Solution

  • If your intent is simply to display the resulting strings:

    var os = require('os');

rep.map(sql.select, null, row => {
    return 'User ' + row.username + ' is ' + row.status;
})
    .then(data=> {
        console.log(data.join(os.EOL));
    });

    Database.map resolves with a new array of returned values, the same as your regular Array.map
