Here is FixMyStreet's Cypress workflow https://github.com/mysociety/fixmystreet/blob/master/.github/workflows/cypress.yml with the master script that sets up server etc at https://github.com/mysociety/fixmystreet/blob/master/bin/browser-tests (that has features such as working inside/outside Vagrant, and can do JS code coverage) and then the tests are at https://github.com/mysociety/fixmystreet/tree/master/.cypress/cypress/integration","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",776635426,

That would save you 9 bytes. But OTOH you need `""use strict"";` to use arrow functions etc, and that's 13 bytes.
Your latest 250-byte one, with use strict, gzips to 199 bytes. The following might be 292 bytes, but compresses to 204, basically the same, and works in any browser (well, IE9+) at all:
`var datasette=datasette||{};datasette.plugins=function(){var d={};return{register:function(b,c,e){d[b]||(d[b]=[]);d[b].push([c,e])},call:function(b,c){c=c||{};var e=[];(d[b]||[]).forEach(function(a){a=a[0].apply(a[0],a[1].map(function(a){return c[a]}));void 0!==a&&e.push(a)});return e}}}();`
Source for that is below; I replaced the [fn,parameters] because closure-compiler includes a polyfill for that, and I ran `closure-compiler --language_out ECMASCRIPT3`:
```js
var datasette = datasette || {};
datasette.plugins = (() => {
var registry = {};
return {
register: (hook, fn, parameters) => {
if (!registry[hook]) {
registry[hook] = [];
}
registry[hook].push([fn, parameters]);
},
call: (hook, args) => {
args = args || {};
var results = [];
(registry[hook] || []).forEach((data) => {
/* Call with the correct arguments */
var result = data[0].apply(data[0], data[1].map(parameter => args[parameter]));
if (result !== undefined) {
results.push(result);
}
});
return results;
}
};
})();

```js
var datasette = datasette || {};
datasette.plugins = (() => {
var registry = {};
return {
register: (hook, fn) => {
registry[hook] = registry[hook] || [];
registry[hook].push(fn);

`var datasette=datasette||{};datasette.plugins=function(){var b={};return{register:function(a,c){b[a]=b[a]||[];b[a].push(c)},call:function(a,c){return(b[a]||[]).map(function(a){return a(c||{})})}}}();`
Called the same, definitions tiny bit different:
```js
datasette.plugins.register('numbers', ({a, b}) => a + b)
datasette.plugins.register('numbers', o => o.a * o.b)
datasette.plugins.call('numbers', {a: 4, b: 6})
