# octopus-file-browser
|
|
|
|
A responsive, framework-free file browser inspired by Gitea. It ships as an accessible Web Component with Material Icon Theme icons and no runtime dependencies.
|
|
|
|
|
|
|
|
## Install
|
|
|
|
```sh
|
|
npm install octopus-file-browser
|
|
```
|
|
|
|
## Use
|
|
|
|
```html
|
|
<octopus-file-browser empty-label="No files"></octopus-file-browser>
|
|
|
|
<script type="module">
|
|
import 'octopus-file-browser';
|
|
|
|
const browser = document.querySelector('octopus-file-browser');
|
|
|
|
async function open(path) {
|
|
const response = await fetch(`/api/ls?path=${encodeURIComponent('/' + path.join('/'))}`);
|
|
const entries = await response.json();
|
|
browser.path = path;
|
|
browser.entries = entries;
|
|
}
|
|
|
|
browser.addEventListener('octopus:navigate', ({ detail }) => open(detail.path));
|
|
browser.addEventListener('octopus:open', ({ detail }) => console.log(detail.path, detail.entry));
|
|
|
|
open([]);
|
|
</script>
|
|
```
|
|
|
|
Importing the package registers `<octopus-file-browser>`. The browser displays one directory at a time: your app sets `path` and that directory's `entries`. Selecting a directory or `..` emits `octopus:navigate` with the requested path, and your app loads that directory and sets both again. Selecting a file emits `octopus:open`.
|
|
|
|
## Entry data
|
|
|
|
| Field | Type | Description |
|
|
| --- | --- | --- |
|
|
| `name` | `string` | Displayed filename. |
|
|
| `type` | `"file" \| "directory"` | Entry kind. |
|
|
| `size` | `number` | File size in bytes. |
|
|
| `modified` | `Date \| string \| number` | Modified time. |
|
|
| `icon` | `string` | Optional custom icon URL. |
|
|
|
|
Directories are sorted before files. Names use natural, case-insensitive sorting.
|
|
|
|
## API
|
|
|
|
| API | Description |
|
|
| --- | --- |
|
|
| `browser.entries` | Gets or replaces the current directory's entries. |
|
|
| `browser.path` | Gets or sets the current directory path, for example `['home', 'ubuntu']`. `..` is shown when it is not empty. |
|
|
| `browser.contextMenu` | Gets or sets the context menu items. Empty by default. |
|
|
| `empty-label` | Attribute controlling the empty-directory message. |
|
|
| `octopus:open` | Event with `{ entry, path }` when a file is selected. |
|
|
| `octopus:navigate` | Event with `{ path }` when a directory or `..` is selected. The browser does not change until your app sets `path` and `entries`. |
|
|
|
|
The package also exports `OctopusFileBrowser`, `createOctopusFileBrowser`, `sortEntries`, `formatFileSize`, `formatRelativeDate`, `isRecent`, and `fileKindLabel`. Type declarations are included.
|
|
|
|
## Context menu
|
|
|
|
The context menu is off until you set items. Right-click, the Menu key, or a touch long press on a file or directory opens it.
|
|
|
|
```js
|
|
browser.contextMenu = [
|
|
{ label: 'Copy path', action: (entry, path) => navigator.clipboard.writeText('/' + path.join('/')) },
|
|
{ label: 'New folder…', when: (entry) => entry.type === 'directory', action: (entry, path) => createFolder(path) },
|
|
{ label: 'Download', when: (entry) => entry.type === 'file', action: (entry, path) => download(path) },
|
|
{ label: 'Validate JSON', when: (entry) => entry.name.endsWith('.json'), action: (entry, path) => validate(path) },
|
|
{ label: 'Delete', danger: true, action: (entry, path) => remove(path) },
|
|
];
|
|
```
|
|
|
|
| Field | Type | Description |
|
|
| --- | --- | --- |
|
|
| `label` | `string` | Menu item text. |
|
|
| `action` | `(entry, path) => void` | Called when the item is selected. |
|
|
| `when` | `(entry, path) => boolean` | Optional. Shows the item only for entries it returns `true` for. Items without `when` show for every entry. |
|
|
| `danger` | `boolean` | Optional. Styles the item as destructive. |
|
|
|
|
Items appear in the order given. When no item matches an entry, the native context menu is shown instead.
|
|
|
|
