Getting Started

npm install @aims-api/aims-tagging-node

Authentication

In order to use the lirbary you need to obtain credentials by contacting us at [email protected]. Credentials consist of CLIENT_ID, CLIENT_SECRET, LOGIN and PASSWORD.

To access protected routes you need to authenticate in order to get a time-limited token. You need to use this token while creating a client instance.

Example with Next.js

It is common to make a proxy request from client app to the server "Next.js API route" in order to hide foreign URL.

You may store the token in a cookie or local storage (browser), but you need to retrieve it from the request object. Storing the token in cookies is recommended for security reasons. In case you decide to store it in cookies, you can set Axios interceptor to check if cookie is still valid and if not, terminate user session in order to obtain a new token.

// pages/api/authenticate.ts

import { NextApiRequest, NextApiResponse } from 'next'
import { Client as TaggingApiClient } from '@aims-api/aims-tagging-node'

export const createClient = async (req: NextApiRequest) => {
  const { clientId, clientSecret } = await getSiteConfigForRequest(req)
  const apiUserToken = getTokenFromCookie(req)

  // You can retrieve auth_token from cookies or local storage
  // Authentication endpoints (e.g. "authenticate", "register", ...)
  // do not require "apiUserToken" field
  return new TaggingApiClient({
    apiHost: 'HOST_URL', // optional
    clientId: 'YOUR_CLIENT_ID', // required
    clientSecret: 'YOUR_CLIENT_SECRET', // required
    apiUserToken: JSON.parse(req.cookies.auth_token),
  })
}

const handler = async (req: NextApiRequest, res: NextApiResponse) => {
  if (req.method === 'POST') {
    try {
      const { userEmail, userPassword } = req.body // credentials: LOGIN, PASSWORD
      // passed from the client-side code
      const aimsClient = createClient(req)
      const response = await aimsClient.endpoints.authentication.authenticate({
        userEmail,
        userPassword,
      })

      const { token, ...rest } = response // removes token from the response to hide
      // from the client-side code (optional)
      return
      res
        .setHeader(
          'Set-Cookie',
          `auth_token=${JSON.stringify(response.token)}; HttpOnly; Secure; path=/`,
        ) // sets token to cookie (optional)
        .status(200)
        .json(rest)
    } catch (error) {
      console.warn(error)
    }
  }
  return res.status(400).json('Method not allowed')
}

export default handler

Usage

When you create a client instance in your codebase, you can then easily access all the existing endpoints via IDE autocomplete, as well as the required and optional parameters.

It's recommended to create a new file for each request handler.

For calling an endpoint batch.startTagging credits are required, for each track in a batch user needs to have exactly one credit. To get information about credits availability, please call apiUser.remainingMonthlyRequests endpoint, property is named remainingMonthlyRequests.

TypeScript

You can import input and response types that are provided in every endpoint file. In order to validate response structure and prevent application from crashing, you may use Zod library.

Example

// src/types/index.ts

...

type Track = Partial<{
  id: string
  title: string
  tags: Tags | null
  filesize: number | null
  duration: number | null
  processedAt: DateTime | null
  hookUrl: string | null
  modelVersion: string
  queuedAt: DateTime | null
  batchId: string | null
}>

Routes

The library provides a set of endpoints that can be found in src/client/index.ts file by the endpoints property on line #175.

Response Structure

Responses are not validated by this library, therefore you need to parse the structure on your own, referring to provided response types. If you find any incosistency, please open an issue or contact us via email.

All endpoints excerpt userData object that contains remainingRequests property, the value is an integer (of type String) that represents the number of credits available for tagging. To access exact response data in the client-side code you need to read response.data.data.

type ResponseType = {
  data: any
  userData: {
    remainingRequests: string
  }
}

This library uses Axios under the hood to make requests, so any network error will be of type AxiosError. Please, check Axios documentation for more information.

Example of parsing an error with Zod on the client side:

// src/helpers/response.ts

import { z } from 'zod'
import { isAxiosError } from 'axios'

interface CustomError {
  status: number | null
  message: string
  field?: string
}

const errorSchema = z.object({
  status: z.number(),
  message: z.string(),
  field: z.optional(z.string()),
})

const notParsed: CustomError = {
  status: 500,
  message: 'Not able to parse error',
}

export const parseError = (error: unknown) => {
  if (isAxiosError(error) && error.response !== undefined) {
    const errorParserResponse = errorSchema.safeParse(error.response.data)
    if (!errorParserResponse.success) {
      return notParsed
    }
    return errorParserResponse.data
  }
  return notParsed
}
