Plugin behavior is coordinated by the Datasette `manager`. Every page has 1 `manager`. There are 2 ways to add your plugin to the `manager`. 1. Read `window.__DATASETTE__` if the manager was already loaded. ```js const manager = window.__DATASETTE__; ``` 2. Wait for the `datasette_init` event to fire if your code was loaded before the manager is ready. ```js document.addEventListener(""datasette_init"", function (evt) { const { detail: manager } = evt; // register plugin here }); ``` 3. Add plugin to the manager by calling `manager.registerPlugin` in a JS file. Each plugin will supply 1 or more hooks with - unique name (`YOUR_PLUGIN_NAME`) - a numeric version (starting at `0.1`), - configuration value, the details vary by hook. (In this example, `getColumnActions` takes a function) ```js manager.registerPlugin(""YOUR_PLUGIN_NAME"", { version: 0.1, makeColumnActions: (columnMeta) => { return [ { label: ""Copy name to clipboard"", // evt = native click event onClick: (evt) => copyToClipboard(columnMeta.column), } ]; }, }); ``` There are 2 plugin hooks available to `manager.registerPlugin`: - `makeColumnActions` - Add items to the cog menu for headers on datasette table pages - `makeAboveTablePanelConfigs` - Add items to ""tabbed"" panel above the `` on pages that use the Datasette table template. While there are additional properties on the `manager`, but it's not advised to depend on them directly as the shape is subject to change. 4. To make your JS file available as a Datasette plugin from the Python side, you can add a python file resembling [this](https://github.com/simonw/datasette/pull/2052/files#diff-c5ecf3d22075a60d04a4e95da2e15c612cf1bc84e38d777b67ba60dbd156e293) to your plugins directory. Note that you could host your JS file anywhere, it doesn't have to be served from the Datasette statics folder. I welcome ideas for more hooks, or feedback on the current design! ## Examples See the [example plugins file](https://github.com/simonw/datasette/blob/2d92b9328022d86505261bcdac419b6ed9cb2236/datasette/static/table-example-plugins.js) for additional examples. ## Hooks API Guide ### `makeAboveTablePanelConfigs` Provide a function with a list of panel objects. Each panel object should contain 1. A unique string `id` 2. A string `label` for the tab 3. A `render` function. The first argument is reference to an HTML [Element](https://developer.mozilla.org/en-US/docs/Web/API/Element). Example: ```js manager.registerPlugin(""panel-plugin-graphs"", { version: 0.1, makeAboveTablePanelConfigs: () => { return [ { id: 'first-panel', label: ""My new panel"", render: node => { const description = document.createElement('p'); description.innerText = 'Hello world'; node.appendChild(description); } } ]; }, }); ``` ### `makeColumnActions` Provide a function that returns a list of action objects. Each action object has 1. A string `label` for the menu dropdown label 2. An onClick `render` function. Example: ```js manager.registerPlugin(""column-name-plugin"", { version: 0.1, getColumnActions: (columnMeta) => { // Info about selected column. const { columnName, columnNotNull, columnType, isPk } = columnMeta; return [ { label: ""Copy name to clipboard"", onClick: (evt) => copyToClipboard(column), } ]; }, }); ``` The getColumnActions callback has access to an object with metadata about the clicked column. These fields include: - columnName: string (name of the column) - columnNotNull: boolean - columnType: sqlite datatype enum (text, number, etc) - isPk: Whether this is the primary key: boolean You can use this column metadata to customize the action config objects (for example, handling different summaries for text vs number columns).

Really appreciate you scaffolding this initial set of types + I think it would be a welcome addition to maintain a set of types.d.ts files. I'm entertaining the idea of writing the actual source code in Typescript as long as the compiled output is readable b/c it can be tricky to keep the types and plain JS files in sync. Curious if you have encountered projects that are good at preventing drift. > Maybe they should have more ""action-y"" names This is a great observation. I'm inclined towards something like `make*` or `build*` since to me `add*` make me think the thing the method is attached to is being mutated, but I agree that any of these may be clearer than the current `get*` setup. I'll go through and update these. > Maybe we can make it easier to do pure-js datasette plugins? I really like this idea! It'll be easier to get contributors if they don't have to touch the python side at _all_. > And then do the PERMITTED_VIEWS filtering in JS rather than Python. One cost of doing this is that pages that won't use the JS would still have to load the unused code (given that I'm not sending up anything complex like lazy loading).

I've been slammed with work/personal stuff so haven't been able to actually prototype anything with this. :( tl;dr: I think this would be useful immediately as is. It might also be nice if the plugins could return `Promise`s. The long version: I read the design notes and example plugin. I think I'd be able to use this in [datasette-ui-extras](https://github.com/cldellow/datasette-ui-extras) for my lazy-facets feature. The lazy-facets feature tries to provide a snappier user experience. It does this by altering how suggested facets work. First, at page render time: (A) it lies to Datasette and claims that no columns support facets, this avoids the lengthy delays/timeouts that can happen if the dataset is large. (B) there's a python plugin that implements the [extra_body_script](https://docs.datasette.io/en/stable/plugin_hooks.html#extra-body-script-template-database-table-columns-view-name-request-datasette) hook, to write out the list of column names for future use by JavaScript Second, at page load time: there is some JavaScript that: (C) makes AJAX requests to suggest facets for each column - it makes 1 request per column, using the data from (B) (D) wires up the column menus to add Facet-by-this options for each facet With the currently proposed plugin scheme, I think (D) could be moved into the plugin. I'd do the ajax requests, then register the plugin. If the plugin scheme also supported promises, I think (B) and (C) could also be moved into the plugin. Does that make sense?

I kindof like the idea of having an ""unstable"" opt-in process to enable JS plugins, to give us time to try it out with a wide variety of plugins until we feel its ready. I'm also curious to see how ""plugins for a plugin' would work, like #1542. For example, if the leaflet plugin showed default markers, but also included its own hook for other plugins to add more markers/styling.

I've pushed both suggested changes onto this branch. > Not sure how difficult it'll be to inject it server-side If we are OK with having a build system, it would free me up to do do many things! We could make datasette-manager.js a server-side rendered file as a ""template"" instead of having it as a static JS file, but I'm not sure it's worth the extra jump in complexity / loss of syntax highlighting in the JS file. In the short-term, I could see an intermediary solution where a unit test in the preferred language was able to read both `version.py` and `datasette-manager.js`, and make sure that the strings versions are in sync. (This assumes that we want the manager and datasette's versions to be synced, and not decoupled). Since the version is not changing very often, a ""manual sync"" might be good enough. > In terms of how to integrate this into Datasette, a few options I can see working: This sounds good to me. I'm not sure how to add a settings flag, but will be interested to see the PR that adds support for it. > I'm also curious to see how ""plugins for a plugin' would work I'm comfortable to wait until we have a realistic usecase for this.
