Why v-text didn't support filter ?

[leupom]

What problem does this feature solve?

Why can't use v-text="doSomething() | filter('args')" ?
Maybe the pipeline operator "|" ?

What does the proposed API look like?

v-text="doSomething() | filter('args')"

Why not use getters when you can or just inline plain javascript otherwise? v-text="filter(doSomething(), 'args')"?
with:

export default {
  methods: {
    doSomething () {...},
    filter () {...}
  }
}

@nickmessing I have registered filter in Vue.filter and don't want to repeat in a new Vue()

According to docs
Vue 2.x filters can only be used inside mustache interpolations and v-bind expressions (the latter supported since 2.1.0), because filters are primarily designed for text transformation purposes. For more complex data transforms in other directives, you should use Computed properties instead

Considering that you want to pass some aditional arguments I think filters is not a good way to go.

I'd prefer:

// filters.js
export myCoolFilter (text, arg1, arg2) => `${text} ${arg1} ${arg2}`

<!-- Component.vue -->
<template>
  <div v-text="myComputed" />
</template>
<script>
  import { myCoolFilter } from './filters.js'

  export default {
    computed: {
      doSomething () {...},
      myComputed () {
        return myCoolFilter(this.doSomething, 'a', 'b')
      }
    }
  }
</script>

Filters are a pretty bad design decision IMO anywhere other than simple text processing like uppercase

You can access your filters in your component like that: this.$options.filters.myCoolFilter. So in v-text you could write: <div v-text="$options.filters.myCoolFilter(myData)"

@nirazul Thanks ^_^

@nirazul

Filters in directives were intentionally removed in Vue 2.0 after intense discussions, and sorry to say that we won't bring them back now, because the situation hasn't changed.

@LinusBorg
I'm ok with this, I think you meant @leupom ;D

[LinusBorg]

Oh, right. Thanks!

Just an example using v-bind

:text-content.prop="text | filter"
