item

The eagle.item API allows you to easily query the current content of the resource library or add new content to the resource library.

eagle.onPluginCreate(async (plugin) => {
    // Get the currently selected file in the Eagle app
    let items = await eagle.item.getSelected();
    let item = items[0];
    
    // Modify attributes
    item.name = 'New Name';
    item.tags = ['tag1', 'tag2'];
    
    // Save modifications
    await item.save();
});

🦄 Best Practice: To ensure data security, use the item API provided save() method for data access and modification, and avoid directly modifying the metadata.json or any files under the Eagle resource library.

Methods

get(options)

Universal search method that can get files with specified conditions.

• options Object - Query conditions

  • id string (optional) - File id

  • ids string[] (optional) - Array of file ids

  • isSelected boolean (optional) - Currently selected files

  • isUntagged boolean (optional) - Files that have not been tagged

  • isUnfiled boolean (optional) - Files that have not been categorized

  • keywords string[] (optional) - Contains keywords

  • tags string[] (optional) - Contains tags

  • folders string[] (optional) - Contains folders

  • ext string (optional) - Format

  • annotation string (optional) - Annotation

  • rating Integer (optional) - Rating, range from 0 ~ 5

  • url string (optional) - Source URL

  • shape string (optional) - Shape, options are square, portrait, panoramic-portrait, landscape, panoramic-landscape

  • fields string[] (optional) - Specify fields to return, only returning needed data to improve performance

• Returns Promise<items: Item[]> - items query result

let items = await eagle.item.get({
    ids: [],
    isSelected: true,
    isUnfiled: true,
    isUntagged: true,
    keywords: [""],
    ext: "",
    tags: [],
    folders: [],
    shape: "square",
    rating: 5,
    annotation: "",
    url: ""
});


let selected = await eagle.item.get({
    isSelected: true
});

let jpgs = await eagle.item.get({
    ext: "jpg"
});

// Get only specific fields to improve performance
let itemsWithFields = await eagle.item.get({
    tags: ["Design"],
    fields: ["id", "name", "tags", "modifiedAt"]
});

Performance Tip: Using the fields parameter can significantly improve performance, especially when handling large numbers of files and only partial information is needed.

---

getAll()

Return all files.

• Returns Promise<items: Item[]> - items all files

let items = await eagle.item.getAll();
console.log(items);

🦄 Best Practice: If the resource library has a large number of files (e.g., 20W+), avoid calling this method without restrictions to avoid reducing application performance.

---

getById(itemId)

Return the file with the specified ID.

• itemId string

• Returns Promise<item: Item> - item the file with the corresponding ID

let item = await eagle.item.getById('item_id');
console.log(item);

getByIds(itemIds)

Return the files with the specified IDs.

• itemIds string[]

• Returns Promise<items: Item[]> - items the files with the corresponding IDs

let items = await eagle.item.getByIds(['item_id_1', 'item_id_2']);
console.log(items);

---

getSelected()

Return the currently selected files in the application.

• Returns Promise<items: Item[]> - items selected files

let selected = await eagle.item.getSelected();
console.log(selected);

---

getIdsWithModifiedAt()

Quickly get IDs and last modified times for all files.

• Returns Promise<items: Object[]> - Array of objects containing id and modifiedAt

// Get all file IDs and modification times for incremental sync
let fileInfo = await eagle.item.getIdsWithModifiedAt();
console.log(fileInfo);
// Output: [{ id: "item_id_1", modifiedAt: 1234567890 }, ...]

// Example: Incremental sync use case
let lastSyncTime = getLastSyncTimestamp();
let allFiles = await eagle.item.getIdsWithModifiedAt();
let modifiedFiles = allFiles.filter(file => file.modifiedAt > lastSyncTime);

// Only fetch full data for files that have been modified
if (modifiedFiles.length > 0) {
    let modifiedIds = modifiedFiles.map(file => file.id);
    let fullData = await eagle.item.getByIds(modifiedIds);
    // Process modified files...
}

Performance Tip: This method is specifically optimized for retrieving file IDs and modification times, and is much faster than using the get() method to retrieve complete data.

---

count(options)

Returns the number of files that match the specified query conditions.

• options Object - Query conditions (same as get() method)

  • id string (optional) - File id

  • ids string[] (optional) - Array of file ids

  • isSelected boolean (optional) - Currently selected files

  • isUntagged boolean (optional) - Files that have not been tagged

  • isUnfiled boolean (optional) - Files that have not been categorized

  • keywords string[] (optional) - Contains keywords

  • tags string[] (optional) - Contains tags

  • folders string[] (optional) - Contains folders

  • ext string (optional) - Format

  • annotation string (optional) - Annotation

  • rating Integer (optional) - Rating, range from 0 ~ 5

  • url string (optional) - Source URL

  • shape string (optional) - Shape, options are square, portrait, panoramic-portrait, landscape, panoramic-landscape

• Returns Promise<count: number> - count number of files matching the query conditions

// Count all selected files
let selectedCount = await eagle.item.count({
    isSelected: true
});

// Count JPG files
let jpgCount = await eagle.item.count({
    ext: "jpg"
});

// Count files with specific tags
let taggedCount = await eagle.item.count({
    tags: ["design", "inspiration"]
});

console.log(`Selected: ${selectedCount}, JPG: ${jpgCount}, Tagged: ${taggedCount}`);

Performance Tip: The count() method is optimized for performance and is more efficient than calling get() and checking the array length when you only need the number of files.

---

countAll()

Returns the total number of files in the resource library.

• Returns Promise<count: number> - count total number of files

let totalCount = await eagle.item.countAll();
console.log(`Total files in library: ${totalCount}`);

Performance Tip: This method is highly optimized and provides a fast way to get the total file count without loading all file data into memory.

---

countSelected()

Returns the number of currently selected files in the application.

• Returns Promise<count: number> - count number of selected files

let selectedCount = await eagle.item.countSelected();
console.log(`Currently selected files: ${selectedCount}`);

// Equivalent to:
// let selectedCount = await eagle.item.count({ isSelected: true });

Performance Tip: This is a convenience method that provides a faster way to count selected files compared to using getSelected().length.

---

select(itemIds)

Select specified files

• itemIds string[] - Array of file IDs to select

• Returns Promise<result: boolean> - result whether the selection was successful

// Select a single file
await eagle.item.select(['ITEM_ID_1']);

// Select multiple files
await eagle.item.select(['ITEM_ID_1', 'ITEM_ID_2', 'ITEM_ID_3']);

// Clear selection
await eagle.item.select([]);

Note: Calling this method will replace the current selection state, rather than appending to existing selected items.

Note: The select() method requires Eagle 4.0 build12 or higher.

---

Hint: You can also directly call the open() method of the item instance to open the file.

---

Class: Item

Object type returned by Eagle API get, provides modification and save features.

🦄 Best Practice: To ensure data security, use save() method provided by the Item instance for data access and modification. Avoid directly modifying metadata.json or any files in the Eagle repository.

---

Instance methods

save()

Save all modifications

• Returns Promise<result: boolean> - result indicates whether the modification was successful

let item = await eagle.item.getById('item_id');
item.name = 'New Name';

Move the file to the trash.

• Returns Promise<result: boolean> - result Indicates whether the deletion was successful.

await item.moveToTrash();

---

replaceFile(filePath)

Replace the original file with the specified file, automatically refreshing the thumbnail without needing to call refreshThumbnail() again.

🦄 Best Practice: Directly modifying the file you want to change can be risky. Errors or exceptions during the process may cause file corruption and be irreversible. Therefore, to ensure a more robust operation, first save the new version of the file in another location on your computer. After verifying it's correct, use the replaceFile() method to replace it.

• filePath string - Path of the file to replace

• Returns Promise<result: boolean> - result indicates whether the replacement was successful

let item = await eagle.item.getById('item_id');
let result = await item.replaceFile('new_file_path');

Refreshes the file thumbnail, and updates the properties like file size, color analysis, dimensions, etc.

• Returns Promise<result: boolean> - result indicates whether the operation was successful

let item = await eagle.item.getById('item_id');
let result = await item.refreshThumbnail();

console.log(result);

---

setCustomThumbnail(thumbnailPath)

Set a custom thumbnail for the file.

• thumbnailPath string - Path of the thumbnail to set

• Returns Promise<result: boolean> - result indicates whether the replacement was successful

let item = await eagle.item.getById('item_id');
let result = await item.setCustomThumbnail('thumbnail_path');

console.log(result);

---

Display this file in the full list

• options Object (optional) - Open options

  • window boolean (optional) - Whether to open the file in a new window, defaults to false

• Returns Promise<void>

Hint: You can also directly call the eagle.item.open(itemId, options) method to open the file.

let item = await eagle.item.getById('item_id');
// Open in current window
await item.open();

// Open in new window
await item.open({ window: true });

// Equivalent to
await eagle.item.open('item_id');
await eagle.item.open('item_id', { window: true });

Note: The window parameter requires Eagle 4.0 build12 or higher.

---

select()

Select this file

• Returns Promise<result: boolean> - result whether the selection was successful

let item = await eagle.item.getById('item_id');
await item.select();

// Equivalent to
await eagle.item.select([item.id]);

Note: Calling the instance method select() will clear the current selection and select only this file. To batch select multiple files, use the static method eagle.item.select(itemIds).

Note: The select() method requires Eagle 4.0 build12 or higher.
