I was tooling around with cradle(https://github.com/cloudhead/cradle) and wanted to create a database if it didn’t exist. Sounds easy enough right, easy peasy ? I thought so too but could not get the code in the documentation to work.
db.exists(function (err, exists) { if (err) { console.log('error', err); } else if (exists) { console.log('the force is with you.'); } else { console.log('database does not exists.'); db.create(); /* populate design documents */ } });
Because I am a noob at node and functional programming in general I neglected to see that the create function should take a callback function as an argument. Reading through the source code led me to create the following mess of code to create a database if it doesnt exist.
db.exists(function (err, exists) { if (err) { console.log('error', err); } else if (exists) { console.log('the force is with you.'); } else { console.log('database does not exists.'); db.create(function(error,response){ if(error) { console.log('error', error) } else { console.log('response', response); } }); /* populate design documents */ } });
So all in all just a couple of wasted hours :)
Thanks go to:
tagio.net, for whom the code was written.
