Hello Team,
How to make a custom helper for templates?

[Julien-R44]

Hello, looks at this : https://docs.adonisjs.com/guides/views/data-flow#globals

You have to define your helpers in an preloaded file so :

node ace make:prldfile ViewHelpers

And select "during HTTP server"

Your .adonisrc.json should contains this now :

{
  "preloads": [
    "./start/routes",
    "./start/kernel",
    {
      "file": "./start/ViewHelpers",
      "environment": [
        "web"
      ]
    }
  ],

Now you can define your helper in start/ViewHelpers :

import View from '@ioc:Adonis/Core/View'

View.global('nl2br', function (text) {
  return text.replace(/([^>\r\n]?)(\r\n|\n\r|\r|\n)/g, '$1<br />$2')
})

In your template :

<p> {{{ nl2br(post.description) }}} </p>
