This package provides a common system for string templating across the Budibase Builder, client and server.
|
||||
The templating is provided through the use of [Handlebars](https://handlebarsjs.com/) an extension of Mustache
|
||||
which is capable of carrying out logic. We have also extended the base Handlebars functionality through the use
|
||||
of a set of helpers provided through the [handlebars-helpers](https://github.com/helpers/handlebars-helpers) package.

|

|
||||
We have not implemented all the helpers provided by the helpers package as some of them provide functionality
|
||||
we felt would not be beneficial. The following collections of helpers have been implemented:
|
||||
1. [Math](https://github.com/helpers/handlebars-helpers/tree/master#math) - a set of useful helpers for

1. [Math](https://github.com/budibase/handlebars-helpers/tree/master#math) - a set of useful helpers for

carrying out logic pertaining to numbers e.g. `avg`, `add`, `abs` and so on.

2. [Array](https://github.com/budibase/handlebars-helpers/tree/master#array) - some very specific helpers
|
||||
for use with arrays, useful for example in automations. Helpers like `first`, `last`, `after` and `join`
|
||||
can be useful for getting particular portions of arrays or turning them into strings.

3. [Number](https://github.com/budibase/handlebars-helpers/tree/master#number) - unlike the math helpers these

4. [URL](https://github.com/budibase/handlebars-helpers/tree/master#url) - very specific helpers for dealing with URLs,
|
||||
such as `encodeURI`, `escape`, `stripQueryString` and `stripProtocol`. These are primarily useful
|
||||
for building up particular URLs to hit as say part of an automation.
|
||||
5. [String](https://github.com/helpers/handlebars-helpers/tree/master#string) - these helpers are useful for building
|
||||
5. [String](https://github.com/budibase/handlebars-helpers/tree/master#string) - these helpers are useful for building
|
||||
strings and preparing them for display, e.g. `append`, `camelcase`, `capitalize` and `ellipsis`.
|

6. [Comparison](https://github.com/budibase/handlebars-helpers/tree/master#comparison) - these helpers are mainly for
|
||||
building strings when particular conditions are met, for example `and`, `or`, `gt`, `lt`, `not` and so on. This is a very
|
||||
extensive set of helpers but is mostly as would be expected from a set of logical operators.
|
||||
7. [Date](https://github.com/helpers/helper-date) - last but certainly not least is a moment based date helper, which can
|
||||
7. [Object](https://github.com/budibase/handlebars-helpers/tree/master#object) - useful operator for parsing objects, as well
|
||||
as converting them to JSON strings.
|
||||
8. [Regex](https://github.com/budibase/handlebars-helpers/tree/master#regex) - allows performing regex tests on strings that
|
||||
can be used in conditional statements.
|
||||
9. [Date](https://github.com/helpers/helper-date) - last but certainly not least is a moment based date helper, which can
|
||||
format ISO/timestamp based dates into something human-readable. An example of this would be `{{date dateProperty "DD-MM-YYYY"}}`.
