The rationale of this change is to improve the inter-operability with web
components that might make use of the `<template>` tag.
DEPRECATION
The template tags and template attribute are deprecated:
<template ngFor [ngFor]=items let-item><li>...</li></template>
<li template="ngFor: let item of items">...</li>
should be rewritten as:
<ng-template ngFor [ngFor]=items let-item><li>...</li></ng-template>
Note that they still be supported in 4.x with a deprecartion warning in
development mode.
MIGRATION
- `template` tags (or elements with a `template` attribute) should be rewritten
as a `ng-template` tag,
- `ng-content` selectors should be updated to referto a `ng-template` where they
use to refer to a template: `<ng-content selector="template[attr]">` should be
rewritten as `<ng-content selector="ng-template[attr]">`
- if you consume a component relying on your templates being actual `template`
elements (that is they include a `<ng-content selector="template[attr]">`). You
should still migrate to `ng-template` and make use of `ngProjectAs` to override
the way `ng-content` sees the template:
`<ng-template projectAs="template[attr]">`
- while `template` elements are deprecated in 4.x they continue to work.
API Examples
This folder contains small example apps that get in-lined into our API docs. Each example contains tests for application behavior (as opposed to testing Angular's behavior) just like an Angular application developer would write.
Running the examples
# # execute the following command only when framework code changes
./build.sh
# run when test change
./modules/@angular/examples/build.sh
# start server
$(npm bin)/gulp serve-examples
navigate to http://localhost:8001
Running the tests
# run only when framework code changes
./build.sh
# run to compile tests and run them
./modules/@angular/examples/test.sh
NOTE: sometimes the http server does not exit properly and it retains the 8001 port.
in such a case you can use lsof -i:8001 to see which process it is and then use kill
to remove it. (Or in single command: lsof -i:8001 -t | xargs kill)
