An index is a basic unit for organizing and storing video data consisting of video embeddings and metadata. Indexes facilitate information retrieval and processing. The Resources.Index class provides methods to manage your indexes.

Properties

Name	Type	Description
`video`	`VideoResource`	Use this property to manage the videos uploaded to this index.

Methods

Create an index

Description: This method creates a new index based on the provided parameters.

Function signature and example:

async create(
  { name, models, addons }: CreateIndexParams,
  options: RequestOptions = {},
): Promise<Models.Index>

const createdIndex = await client.index.create({
  name: '<YOUR_INDEX_NAME>',
  models: [
    {
      name: 'marengo2.7',
      options: ['visual', 'audio'],
    },
  ],
  addons: ['thumbnail'],
});
console.log(`ID: ${createdIndex.id}`);
console.log(`Name: ${createdIndex.name}`);
console.log("Models:");
createdIndex.models.forEach((model, index) => {
  console.log(`  Model ${index + 1}:`);
  console.log(`    Name: ${model.name}`);
  console.log(`    Options: ${JSON.stringify(model.options)}`);
});
console.log(`Video count: ${createdIndex.videoCount}`);
console.log(`Total turation: ${createdIndex.totalDuration} seconds`);
console.log(`Created at: ${createdIndex.createdAt}`);
if (createdIndex.updatedAt) {
  console.log(`Updated at: ${createdIndex.updatedAt}`);
}

Parameters

Name	Type	Required	Description
`params`	`CreateIndexParams`	Yes	Parameters for creating the index.
`options`	`RequestOptions`	No	Additional options for the request. Defaults to `{}`.

The CreateIndexParams interface has the following properties:

List indexes with direct pagination

Description: The list method retrieves a paginated list of indexes based on the provided parameters. Choose this method mainly when the total number of items is manageable, or you must fetch a single page of results. By default, the platform returns your indexes sorted by creation date, with the newest at the top of the list.

Function signature and example:

async list(
  { id, name, createdAt, updatedAt, ...restParams }: ListIndexParams = {},
  options: RequestOptions = {},
): Promise<Models.Index[]>

const listParams = {
  id: '<YOUR_INDEX_ID>',
  name: '<YOUR_INDEX_NAME>',
  modelOptions: ['audio', 'visual'],
  modelFamily: 'marengo',
  page: 1,
  pageLimit: 5,
  sortBy: 'updated_at',
  sortOption: 'asc'
};

const indexes = await client.index.list(listParams);
indexes.forEach(index => {
  console.log(`ID: ${index.id}`);
  console.log(`  Name: ${index.name}`);
  console.log("  Models:");
  index.models.forEach((model, index) => {
    console.log(`    Model ${index + 1}:`);
    console.log(`      Name: ${model.name}`);
    console.log(`      Options: ${JSON.stringify(model.options)}`);
  });
  console.log(`  Video count: ${index.videoCount}`);
  console.log(`  Total duration: ${index.totalDuration} seconds`);
  console.log(`  Created at: ${index.createdAt}`);
  if (index.updatedAt) {
    console.log(`  Updated at: ${index.updatedAt}`);
  }
});

Parameters

Name	Type	Required	Description
`params`	`ListIndexParams`	No	Parameters for retrieving the list of indexes. Defaults to `{}`.
`options`	`RequestOptions`	No	Additional options for the request. Defaults to `{}`.

The ListIndexParams interface extends the PageOptions interface and defines the parameters for listing indexes:

`modelOptions`	`string[]`	No	Filter by model options.
`modelFamily`	`'marengo' \	'pegasus'`	No
`createdAt`	string \	Record`<string, string>`	No
`updatedAt`	string \	Record`<string, string>`	No

Name	Type	Required	Description
`page`	`number`	No	Page number for pagination. Defaults to 1.
`pageLimit`	`number`	No	Number of items per page. Defaults to 10.
`sortBy`	`'createdAt' \	'updatedAt'`	No
`sortOption`	`'asc' \	'desc'`	No

Return value: Returns a Promise that resolves to an array of Models.Index instances.

List indexes with iterative pagination

Description: This method iterates through a paginated list of indexes based on the provided parameters. Choose this method mainly when your application must retrieve a large number of items. By default, the platform returns your indexes sorted by creation date, with the newest at the top of the list.

Function signature and example:

  async listPagination(
    { id, name, createdAt, updatedAt, ...restParams }: ListIndexParams = {},
    options: RequestOptions = {},
  ): Promise<Models.IndexListWithPagination>

function printIndexPage(indexPage) {
  indexPage.forEach(index => {
    console.log(`ID: ${index.id}`);
    console.log(`  Name: ${index.name}`);
    console.log("  Models:");
    index.models.forEach((model, index) => {
      console.log(`    Model ${index + 1}:`);
      console.log(`      Name: ${model.name}`);
      console.log(`      Options: ${JSON.stringify(model.options)}`);
    });
    console.log(`  Video count: ${index.videoCount}`);
    console.log(`  Total duration: ${index.totalDuration} seconds`);
    console.log(`  Created at: ${index.createdAt}`);
    if (index.updatedAt) {
      console.log(`  Updated at: ${index.updatedAt}`);
    }
  });
}

const listParams = {
  id: '66e9358a808d95368f6f7a7c',
  name: 'sdk-ref-index-create-01',
  modelOptions: ['audio', 'visual'],
  modelFamily: 'marengo',
  page: 1,
  pageLimit: 5,
  sortBy: 'updated_at',
  sortOption: 'asc'
};

// Fetch the initial page of results
const indexPaginator = await client.index.listPagination(listParams);

// Print the first page of results
printIndexPage(indexPaginator.data);

// Iterate through subsequent pages
while (true) {
  const nextIndexPage = await indexPaginator.next();
  if (!nextIndexPage) {
    console.log('No more pages of index results available');
    break;
  }
  printIndexPage(nextIndexPage);
}
