mattbasta/jinja2js

A project to let you compile Jinja2 templates to JavaScript.

Jinja2JS

WARNING! This project is completely unmaintained. Contributions will still be accepted, but it is unlikely that this project will be developed actively in the future. Consider using Mozilla's Nunjucks instead.

Usage

python compile_to_js.py /path/to/jinja2/template

The above command will yield a JavaScript function which, when executed with a JSON blob containing values that correspond to the values requested by the template as the first argument, will yield a rendered version of the template.

Adding the --attributes flag to the command will return a list of values which the template expects to be provided in the JSON. This list may be more useful if piped through | sort | uniq.

Unsupported Jinja Features

As of the latest version, the following features are unimplemented or not supported:

• Template inheritance (the content of each declared block is returned).
• Imports
• Includes
• Filters and filter blocks
• for loops
• Macros
• Call blocks
• Client-side inline dicts, tuples, and lists.
• Slice steps in client side code.
• Tests

Considerations

• Content that it output outside of a block is placed in the __default__ block.
