Ember-template-helper-import NPM

ember-template-helper-import

forked from https://github.com/crashco/ember-template-component-import and changed to allow helper imports This is to be used alongside https://github.com/crashco/ember-template-component-import

This addon allows you to use import-style syntax to create local bindings to a helper within a template file.

More concise helpers invocation while making it explicit where it comes from
No hyphens needed!
Relative imports!
Currently only tested with simple helpers

Installation

ember install ember-template-helper-import

Usage

Use the same kind of import syntax you are familiar with from Javascript:

{{import myHelper from 'ui/helper'}}

{{myHelper 'a'}}

{{import helper as ashelper from "ui/helpers" }}
{{import a as ahelper from "ui/helpers" }}
{{import "* as helpers" from "u/helpersi" }}
{{import "a, b" from "ui/helpers" }}
{{import "a as x, b as y" from "ui/helpers" }}
{{import "a as z, helper" from "ui/helpers" }}

The helper is looked up from the given string using a direct lookup pattern. I set the resolveHelper in the resolver. All this addon does is taking that {{import ...}} statement and replacing all helper invocations with {{ember-template-helper-import/helpers/invoke-helper 'myHelper' ...}}.

Our helper then looks up the actual helper and calls compute with the other arguments

Motivation

ember-template-component-import already gives us import for components, but I really miss the helper imports. So I went ahead and added this functionality :)

But what about Module Unification?

Once Module Unification lands fully, this addon will be largely obsolete. MU provides all these benefits and more.

So on the one hand, your templates will start to look something kinda like MU a little sooner, which is nice.

But be warned - any official tooling to codemod templates into a new MU world likely won't support this addon. So weigh the pros and cons carefully before widely adopting this addon.
