Display Handlebars.js context in a template

Question

Is there a variable passed into every handlebar.js template that contains all the context content that is accessible by the template?

e.g. I'm creating a template, but I don't know all the context content accessible by the template. I want to be able to type into the template {{ debug }} and handlebars.js will spit out all the context content into the HTML

You mean like [this](http://thinkvitamin.com/code/handlebars-js-part-3-tips-and-tricks/)? — MilkyWayJoe, Jun 27 '12 at 17:17
No big deal, it's not really an *answer*. I'm glad it helps. — MilkyWayJoe, Jun 27 '12 at 17:32
The solution in the link does not return the data, does anyone have a reliable way to view access context data within a template? — jdcravens, Mar 25 '13 at 21:18

You can use the following code to iterate through this object:

{{#each this}}
  {{@key}}: {{this}}
{{/each}}

or a similar piece of code iterating through @root object:

{{#each @root}}
  {{@key}}: {{this}}
{{/each}}

Handlebars has built-in helper log.

You just need to set logging level to DEBUG.

Handlebars.logger.level = 0;

Then use helper:

{{log this}}

EDIT: Sorry, this will not write context to HTML, helper uses console.log. For outputting to HTML you need to write custom helper that will use for example JSON.stringify.

Though this question is somewhat old, someone might find this usefull. You can just dump the handlebars current context into plain text with;

{{{.}}}

I tried this and all i see is an "object object" how to do this within a template – DJ22T May 04 '16 at 15:33
did you try with 'triple-stash' `{{{` ? because then handlebars will not try to escape values and try to convert toString(). – Govinnage Rasika Perera May 04 '16 at 16:32
Copied and pasted my friend :) although I got a different approach – DJ22T May 04 '16 at 17:48

for me to see the object I needed to register a helper in my app.js: `hbs.registerHelper('json', (object) => JSON.stringify(object));` then in my view `{{{json .}}}` – Michael Mueller Mar 24 '20 at 12:40
