As we know that parse services on which 80% ratio of top mobile app development companies rely on is getting retired in the forthcoming year dated on January 28, 2017. So a backup needs to be taken of our app and its related data and services for which they are releasing database migration tool named MongoDB database during which the PARSE API will work as normal based on your newly migrated database that takes minimal amount of in-activeness.
Now let’s have a look below that gives you brief understanding about how we can migrate our app to MongoDB ...!
1) Firstly, we need to migrate our data from parse hosted app to MongoDB and after that we need to set MongoDB instance that conforms with our database specifications.
2) Once the instance is been initialized check Mongo connection string(URL) and then transfer your data to external database. Here we need to ensure that the user specified in connection string should have admin privileges as during migration process it will axiomatically set some parameters which we are not aware of.
3) Once everything is confirmed then you can finalize your transfer of UI/UX and your application will be striking to api.parse.com but will be using new instance of Mongo DB.
Setting Up Local Parse Server:
4)Now, Set up a Local parse Server where you will be using connection string created above and then follow below instructions:
Pass all these keys into constructor created in index.js page.
Checking Cloud Code:
5) Now we need to migrate your existing cloud code to run in parse server and for that we need to make a replica of cloud code into the Server of Parse in place of main.js.Once done with it make some calls to few of your cloud code to verify your code are working properly or not.
6) If one is using Parse Hosting, it can migrate all these web endpoints to Express app serving Parse Server.
Perform Application Setting:
7) Ensure all application level settings like:
Social Media Authentication
Application Testing & Compatibility Issues:
8) At this point check your application locally whether server is pointing to the same instance and all the functions are working appropriately as they need to or not. We are also required to check compatibility issues arising as many times parse server do not provide compatibility with hosted back end of parse.
Setting of Parse Server on Heroku:
9) Now deploy your parse server on heroku and check whether your client is pointing to API deployed on Heroku.
Testing & Publishing:
10) Now test your app whether it uses Heroku back end or not and then publish the new app of yours that will now formerly use Heroku as its back end.
