Package name in a new Flutter project

Sherin — Thu, 15 Aug 2019 08:46:50 +0000

If you are someone like me, who uses Visual Studio Code to work with Flutter, you would most likely be using Flutter CLI to create new flutter projects.

Flutter CLI, by default, would use com.example.project_name as your package name/bundle identifier. If you want to specify to change that behaviour, you can run

flutter create --org com.my_cool_org project_name

This would set the Android package name to com.my_cool_org.project_name and iOS bundle identifier to com.myCoolOrg.projectName

exports vs module.exports in Node.js

exports.id = 1; //this is ok

exports = {id: 1}; //this is not ok

module.exports = {id: 1}; //this is ok

WHY?

exports is simply a variable reference to module.exports. So we can change the properties of the exports object, but if we change the whole object, it would no longer be a reference to module.exports

You can use require.resolve() to check whether a dependency is available in your Node.js app without loading it. You can read more about it here

Building your application after pushing to Heroku

When deploying their application to Heroku, most people will run development script for their application. This will tremendously increase the loading time of your application. Instead you can build a production-ready version of your application after pushing your application to Heroku making use of heroku-postbuild script in your package.json
