issues

Motivation

• I have a directory of sqlite databases
• I'd like to use immutable mode when opening them for better performance docs

• Currently using this flag throws the following error

  IsADirectoryError: [Errno 21] Is a directory: '/name-of-directory'

Proposal

Immutable flag works for both single files and directories

datasette -i /folder-of-sqlite-files

Motivation

• The build system for my new plugin has two output JS files, one for browsers that support ES modules, one for browsers that don't. At present, I'm only passing one of them into Datasette.
• I'd like to specify the non-es-module script as a fallback for older browsers. I don't want to load it by default, because browsers will only need one, and it's heavy, so for now I'm only supporting modern browsers.

To be able to support legacy browsers without slowing down users with modern browsers, I would like to be able to set additional HTML attributes on the tag fallback script, nomodule and defer. My injected scripts should look something like this:

```html

<script type="module" src="/index.my-es-module-bundle.js"></script> <script src="/index.my-legacy-fallback-bundle.js" nomodule="" defer></script>

```

Proposal

To achieve this, I propose additional optional properties to the API accepted by the extra_js_urls hook and custom JS field the metadata.json described here.

Under this API, I'd write something like this to get the above HTML rendered in Datasette.

json { "extra_js_urls": [ { "url": "/index.my-es-module-bundle.js", "module": true, }, { "url": "/index.my-legacy-fallback-bundle.js", "nomodule": "", "defer": true } ] }

Resources

• MDN on the script tag
• There may be other properties that could be added that are potentially valuable, like async or referrerpolicy, but I don't have an immediate need for those.

I'm trying to make a small plugin that depends on static assets, by following the guide here. I made a plugins/ directory with datasette_nteract_data_explorer.py.

I am trying to follow the example of datasette_vega, and serving static assets. I created a statics/ directory within plugins/ to serve my JS and CSS.

https://github.com/simonw/datasette-vega/blob/00de059ab1ef77394ba9f9547abfacf966c479c4/datasette_vega/init.py#L13

Unfortunately, datasette doesn't seem to be able to find my assets.

Input:

bash datasette ~/Library/Safari/History.db --plugins-dir=plugins/

Output:

I suspect this issue might go away if I move away from "one-off" plugin mode, but it's been a while since I created a new python package so I'm not sure how much work there is to go between "one off" and "packaged for PyPI". I'd like to try to avoid needing to repackage a new tar.gz file and or reinstall my library repeatedly when developing new python code.

1. Is there a way to serve a static assets when using the plugins/ directory method instead of installing plugins as a new python package?
2. If not, is there a way I can work on developing a plugin without creating and repackaging tar.gz files after every change, or is that the recommended path?

Thanks for your help!
