bokeh.resources¶

The resources module provides the Resources class for easily configuring how BokehJS code and CSS resources should be located, loaded, and embedded in Bokeh documents.

Additionally, functions for retrieving Subresource Integrity hashes for Bokeh JavaScript files are provided here.

Some pre-configured Resources objects are made available as attributes.

CDN¶: load minified BokehJS from CDN

INLINE¶: provide minified BokehJS from library static directory

class CSSResources(mode=None, version=None, root_dir=None, minified=None, legacy=None, log_level=None, root_url=None, path_versioner=None, components=None, base_dir=None)[source]¶

The CSSResources class encapsulates information relating to loading or embedding Bokeh client-side CSS.

Parameters

mode (str) –
how should Bokeh CSS be included in output

See below for descriptions of available modes
version (str, optional) –
what version of Bokeh CSS to load

Only valid with the 'cdn' mode
root_dir (str, optional) –
root directory for loading BokehJS resources

Only valid with 'relative' and 'relative-dev' modes
minified (bool, optional) – whether CSS should be minified or not (default: True)
root_url (str, optional) –
URL and port of Bokeh Server to load resources from

Only valid with 'server' and 'server-dev' modes

The following mode values are available for configuring a Resource object:

'inline' configure to provide entire BokehJS code and CSS inline
'cdn' configure to load Bokeh CSS from https://cdn.bokeh.org
'server' configure to load from a Bokeh Server
'server-dev' same as server but supports non-minified CSS
'relative' configure to load relative to the given directory
'relative-dev' same as relative but supports non-minified CSS
'absolute' configure to load from the installed Bokeh library static directory
'absolute-dev' same as absolute but supports non-minified CSS

Once configured, a Resource object exposes the following public attributes:

css_raw¶: any raw CSS that needs to be places inside <style> tags

css_files¶: URLs of any CSS files that need to be loaded by <link> tags

messages¶: any informational messages concerning this configuration

These attributes are often useful as template parameters when embedding Bokeh plots.

class JSResources(mode=None, version=None, root_dir=None, minified=None, legacy=None, log_level=None, root_url=None, path_versioner=None, components=None, base_dir=None)[source]¶

The Resources class encapsulates information relating to loading or embedding Bokeh Javascript.

Parameters

mode (str) –

See below for descriptions of available modes
version (str, optional) –
what version of Bokeh JS to load

Only valid with the 'cdn' mode
root_dir (str, optional) –
root directory for loading Bokeh JS assets

Only valid with 'relative' and 'relative-dev' modes
minified (bool, optional) – whether JavaScript should be minified or not (default: True)
root_url (str, optional) –
URL and port of Bokeh Server to load resources from (default: None)

If None, absolute URLs based on the default server configuration will be generated.

root_url can also be the empty string, in which case relative URLs, e.g., “static/js/bokeh.min.js”, are generated.

get_all_sri_hashes()[source]¶

Report SRI script hashes for all versions of BokehJS.

Bokeh provides Subresource Integrity hashes for all JavaScript files that are published to CDN for full releases. This function returns a dictionary that maps version strings to sub-dictionaries that JavaScipt filenames to their hashes.

Returns: dict

Example

The returned dict will map version strings to sub-dictionaries for each version:

{
    '1.4.0': {
        'bokeh-1.4.0.js': 'vn/jmieHiN+ST+GOXzRU9AFfxsBp8gaJ/wvrzTQGpIKMsdIcyn6U1TYtvzjYztkN',
        'bokeh-1.4.0.min.js': 'mdMpUZqu5U0cV1pLU9Ap/3jthtPth7yWSJTu1ayRgk95qqjLewIkjntQDQDQA5cZ',
        ...
    }
    '1.3.4': {
        ...
    }
    ...
}

get_sri_hashes_for_version(version)[source]¶

Report SRI script hashes for a specific version of BokehJS.

Bokeh provides Subresource Integrity hashes for all JavaScript files that are published to CDN for full releases. This function returns a dictionary that maps JavaScript filenames to their hashes, for a single version of Bokeh.

Parameters: version (str) – The Bokeh version to return SRI hashes for. Hashes are only provided for full releases, e.g “1.4.0”, and not for “dev” builds or release candidates.
Returns: dict
Raises: KeyError – if the specified version does not exist

Example

The returned dict for a single version will map filenames for that version to their SRI hashes:

{
    'bokeh-1.4.0.js': 'vn/jmieHiN+ST+GOXzRU9AFfxsBp8gaJ/wvrzTQGpIKMsdIcyn6U1TYtvzjYztkN',
    'bokeh-1.4.0.min.js': 'mdMpUZqu5U0cV1pLU9Ap/3jthtPth7yWSJTu1ayRgk95qqjLewIkjntQDQDQA5cZ',
    'bokeh-api-1.4.0.js': 'Y3kNQHt7YjwAfKNIzkiQukIOeEGKzUU3mbSrraUl1KVfrlwQ3ZAMI1Xrw5o3Yg5V',
    'bokeh-api-1.4.0.min.js': '4oAJrx+zOFjxu9XLFp84gefY8oIEr75nyVh2/SLnyzzg9wR+mXXEi+xyy/HzfBLM',

    'bokeh-widgets-1.4.0.js': 'scpWAebHEUz99AtveN4uJmVTHOKDmKWnzyYKdIhpXjrlvOwhIwEWUrvbIHqA0ke5',
    'bokeh-widgets-1.4.0.min.js': 'xR3dSxvH5hoa9txuPVrD63jB1LpXhzFoo0ho62qWRSYZVdyZHGOchrJX57RwZz8l'
}

verify_sri_hashes()[source]¶

Verify the SRI hashes in a full release package.

This function compares the computed SRI hashes for the BokehJS files in a full release package to the values in the SRI manifest file. Returns None if all hashes match, otherwise an exception will be raised.

Note

This function can only be called on full release (e.g “1.2.3”) packages.

Returns

None

Raises

ValueError – If called outside a full release package
RuntimeError – If there are missing, extra, or mismatched files
