How to use node modules (like MomentJS) in EJS views?

Question

To use MomentJS in views/custom.ejs, what is the correct way (if any)?

1. Server side

   routes/index etc we can easily use require(\'moment\');

Answer 1

var moment = require('moment');
app.locals.moment = require('moment');

Use in the view:

<%= moment(myDateValue).fromNow() %>

Now you can simply use moment in your EJS files.

Answer 2

You can create the function and attach it to the app.locals. and use it in the ejs template on the server side.

In your routes file you do

../routes/page.js

var ejs = require('ejs')
  , moment = require('moment');

app.locals.fromNow = function(date){
  return moment(date).fromNow();
}

../views/page.ejs

<span class="created_at"><%= fromNow(item.created_at) %></span>

Just remember to have moment added to to your package.json file

Answer 3

I wrote a helpers to return moment for using on ejs view and layouts.

./helpers/utils/get-moment.js

const moment = require('moment');

module.exports = {
    friendlyName: 'formatMoney',
    description: 'format money number.',
    inputs: {},
    sync: true,
    exits: {},
    fn: function (inputs, exits) {
        return exits.success(moment);
    }
};

Then using:

const moment = sails.helpers.utils.getMoment();

Answer 4

As of Node v12.8.3, it seems that you can pass require directly to EJS templates, i.e. this works:

const ejs = require('ejs')
let renderedHTML = ejs.render(`<% const moment = require('moment') %>`, { require })
