eslint-plugin-jinja

This plugin treats Jinja template expressions and statements as valid Javascript expressions, so that ESLint can check javascript code, ignoring any Jinja expression found.

As a note, it is possible that this best effort conversion yeilds false negatives or positives because it is impossible to know the right way to insert placeholders.

Example

Plugin will convert (internally) this code:

unction() {
'use strict';

{# plain jinja variables are converted into strings
  (preferred quotes are getting from .eslintrc file) #}

var a = 'this is' + {{ some_variable }};

{# if it is already in string, it is wrapped with spaces #}

var b = 'this is {{ other_variable }}';
var c = 'and this is {{ another_one['field']}}';

{# if-else statements are converted into ( ..., ... ) expression #}

var d = {% if something %} 'this is something' {% else %} null {% endif %};

{# any other statements become comments #}

{% for i in [1, 2, 3] %}
  console.log(a, b, c, d);
{% endfor %}
();

into this:

nction() {
'use strict';

/* plain jinja variables are converted into strings
  (preferred quotes are getting from .eslintrc file) */

var a = 'this is' + '  some_variable  ';

/* if it is already in string, it is wrapped with spaces */

var b = 'this is    other_variable   ';
var c = 'and this is    another_one[ field ]  ';

/* if-else statements are converted into ( ..., ... ) expression */

var d = (/*if something */ 'this is something' ,/*else */ null /*endif */);

/* any other statements become comments */

/* for i in [1, 2, 3] */
  console.log(a, b, c, d);
/* endfor */
();
