Method to get current year?

[ecupaio]

I'm attempting to display a copyright year on my email template but I'm unsure of a method where I can get the date without using javascript. If I write a script it gets compiled to the production template instead of printing the value so I'm wondering if there's something in the configs I can just pull out and place as a variable like I did with the frontmatter in the templates.

I think that you can use a function for that.

In config.js:

current_year: function() {
    return new Date().getFullYear()
}

In your template:

<p>{{ page.current_year }}</p>

Yup that's how I do it too 👍

You can even take it a step further and remove the need for page. in the expression by defining the method as a top-level variable - https://maizzle.com/docs/environments#top-level-variables

module.exports = {
  locals: {
    current_year: function() {
      return new Date().getFullYear()
    }
  }
}

You'd then just do:

<p>{{ current_year }}</p>

noice! I'm adding page.current year to my layout file and it works. What would be the use case of a top level variable?

[michellaurent]

@ecupaio The only advantage is that you don't have to prefix the variable name with page.

[cossssmin]

Mostly if you don't want to write page. all the time, or if you somehow really need to separate data within them.

[ecupaio]

got it. thanks for the tip!

oh nice! This works. To provide the wisdom of the ancients, here's exactly what I did to achieve this:
In config.js, I added the current_year function to the module.exports object.:
config.js

module.exports = {
  build: {
    templates: {
      source: 'src/templates',
      destination: {
        path: 'build_local',
      },
      assets: {
        source: 'src/images',
        destination: 'images',
      },

    },
  },
  current_year: function() {
      return new Date().getFullYear()
  }
}

Then in my layout I added the following code:

<p>{{ page.current_year }}</p>

You can add this to your template files as well.

You don't have to do it in both config files. They are merged together.

[ecupaio]

so just inside the config file yeah?

[michellaurent]

Yes.
