ngAir 79 - ng1 to ng2 Migration with Joe Eames

#Show Notes

Intro

Joe’s background with migrations

Pluralsight course

Refactoring your ng1 app
before migrating to ng2

Component based
architecture

What are the different approaches? 3 options:

Big bang - should only do if
takes a couple weeks, less than 10k lines of code

Leave it alone - Maintain it
in Angular 1

Slowly convert - Angular 1
app that calls Angular 2 for some pieces

Can convert any Angular 2 component into Angular 1 directive

When slowly converting, important to mitigate risk by
doing smaller changesets

Performance

Angular 2 an order of
magnitude faster

Angular 1 is the slow piece

Overhead with cooridination,
but not that much

What to do if no tests in current ng1 app?

Do you need to have two http services running?

What do you think of Angular’s approach to migration
compared to Ember’s?
