that's what we did:
```python
from superset import manifest_processor
from superset.extensions import UIManifestProcessor
def extend_ui_manifest():
"""
Makes our custom JS files to be executed on every HTML page.
In order to add JS file, go to `/static/assets/dist/manifest.json`
and add path to JS file within the `/static` folder, e.g:
>>> {
>>> "js": [
>>> "welcome/walkme.js",
>>> "hello.js",
>>> ]
>>> }
"""
with open(os.path.join(SIMPLESET_STATIC_DIR, "assets", "dist",
"manifest.json")) as fp:
manifest = json.load(fp)
parse_manifest_json = UIManifestProcessor.parse_manifest_json
def custom_parse_manifest_json(self):
parse_manifest_json(self)
entrypoints = self.manifest.setdefault("theme", {"js": []})["js"]
for js_path in manifest["js"]:
# /static handled by our custom static view
entrypoints.append(os.path.join("/static", js_path))
UIManifestProcessor.parse_manifest_json = custom_parse_manifest_json
manifest_processor.parse_manifest_json()
```
But in order for this to work, you also need to patch superset static, e.g:
```python
def flask_app_mutator(app):
def superset_static(self, filename): # vendored from flask and modified
to support our static files
if not self.has_static_folder and not
self.config.get("SUPERSET_STATIC"):
raise RuntimeError("No static folder for this object")
# Ensure get_send_file_max_age is called in all cases.
# Here, we ensure get_send_file_max_age is called for Blueprints.
cache_timeout = self.get_send_file_max_age(filename)
for static_folder in filter(None,
(self.config.get("SUPERSET_STATIC"), self.static_folder)):
with contextlib.suppress(NotFound):
return send_from_directory(
static_folder, filename, cache_timeout=cache_timeout
)
raise NotFound
extend_ui_manifest()
app.view_functions["static"] = MethodType(superset_static, app) # hack
```
And then you simply edit that manifest from our static folder:
```json
{
"js": [
"walkme.js",
"a/b/c/hello.js"
]
}
```
Above JS files will be loaded along with `base.html`
