Visit Key Concepts page to learn the most important QuickBlox concepts.

​
Before you begin

  1. Register a QuickBlox account. This is a matter of a few minutes and you will be able to use this account to build your apps.
  2. Configure QuickBlox SDK for your app. Check out Setup page for more details.
  3. Create a user session to be able to use QuickBlox functionality. See Authentication page to learn how to do it.

​
Create user

It’s recommended to manage user creation at your backend for production. To learn more you can refer to QuickBlox API documentation. For POCs/MVPs or during development you may want to create users on the fly, you can use create() method. Create a user using the code snippet below. Only login (or email) and password are required. Other fields are optional.
JavaScript
const createUserParams = {
  email: '[[email protected]](/cdn-cgi/l/email-protection)',
  fullName: 'Jack Sparrow',
  login: 'jack',
  password: 'jackpassword',
  phone: '404-388-5366',
  tags: ['awesome', 'quickblox']
};

QB.users
  .create(createUserParams)
  .then(function (user) {
    // user created successfully
  })
  .catch(function (e) {
    // handle as necessary
  });
Security & PrivacyIt’s recommended to disable permission to create users with application session on production apps once user creation is implemented on your backend.Email, full name, facebookId and phone number are PII, configure session permissions according to your privacy requirements.

​
Retrieve users

Get a list of users using the getUsers() method below. The code snippet below shows how to get a list of users with full_name containing John, sorted by the updated_at field in descending order, and limited to 10 users on the page.
JavaScript
// * @param {Object} result
// * @param {QBUser[]} result.users Array of users returned from API request
// * @param {number} result.page Page of results
// * @param {number} result.perPage How much items returned per page
// * @param {number} result.total Total amount of results

function processUsers(result) {
  //
}

const filter = {
  field: QB.users.USERS_FILTER.FIELD.FULL_NAME,
  type: QB.users.USERS_FILTER.TYPE.STRING,
  operator: QB.users.USERS_FILTER.OPERATOR.IN,
  value: 'John'
};

const sort = {
  ascending: false,
  field: QB.users.USERS_SORT.FIELD.LAST_REQUEST_AT,
  type: QB.users.USERS_SORT.TYPE.STRING
};

const getUsersQuery = {
  filter: filter,
  sort: sort,
  page: 1,
  perPage: 10
};

QB.users
  .getUsers(getUsersQuery)
  .then(processUsers)
  .catch(function (error) {
    // handle error
  });
The method getUsers() accepts one (optional) argument of the object type that has the following fields:
FieldRequiredDesription
filternoSpecifies filtering criteria for the field.
sortnoSpecifies sorting criteria for the field.
pagenoNumber of pages with results to be returned.
perPagenoNumber of records to return in one page.
If you want to retrieve only users updated after some specific date time, you can use operators. This is useful if you cache users somehow and do not want to obtain the whole list of your users on every app start. Thus, you can use search operators and sort operators to list users on the page so that it is easier to see specific users.

​
Search operators

You can use search operators to get more specific search results. The request below will return users filtered by IDs.
JavaScript
const occupantsIds = dialog.occupantsIds;
const filter = {
  field: QB.users.USERS_FILTER.FIELD.ID,
  type: QB.users.USERS_FILTER.TYPE.NUMBER,
  operator: QB.users.USERS_FILTER.OPERATOR.IN,
  value: occupantsIds.join() // value should be of type String
};

const getUsersQuery = {
  filter: filter
};

function processUsers(result) {}

QB.users
  .getUsers(getUsersQuery)
  .then(processUsers)
  .catch(function (e) {
    // handle error
  });
Here are the search operators that you can use to search for the exact data that you need.
Search operatorsApplicable to typesApplicable to fieldsDescription
ltnumber, string, dateid, created_at, updated_at, last_request_at, external_user_id, facebook_idLess Than operator.
genumber, string, dateid, created_at, updated_at, last_request_at, external_user_id, facebook_idGreater Than or Equal to operator.
gtnumber, string, dateid, created_at, updated_at, last_request_at, external_user_id, facebook_idGreater Than operator.

innumber, string, dateid, full_name, email, login, phone, created_at, updated_at, last_request_at, external_user_id, facebook_idIN array operator.

​
Sort operators

You can use sort operators to order the search results. The request below will return users sorted in descending order by the last date a user was requested.
JavaScript
const sort = {
  ascending: false,
  field: QB.users.USERS_SORT.FIELD.LAST_REQUEST_AT,
  type: QB.users.USERS_SORT.TYPE.STRING
};

const getUsersQuery = {
  sort: sort
};

function processUsers(result) {}

QB.users
  .getUsers(getUsersQuery)
  .then(processUsers)
  .catch(function (e) {
    // handle error
  });
Here are the sort options that you can use to order the search results:
Sort optionsApplicable to typesApplicable to fieldsDescription
ascendingAll typesid, full_name, email, login, phone, website, created_at, updated_at,last_request_at, external_user_idSort results in the ascending order by setting the ascending as true.
descendingAll typesid, full_name, email, login, phone, website, created_at, updated_at,last_request_at, external_user_idSort results in the ascending order by setting the ascending as false.
fieldString, Number, Dateid, full_name, email, login, phone, website, created_at, updated_at, last_request_at, external_user_idSort Field Value
typeString, Number, Dateid, full_name, email, login, phone, website, created_at, updated_at, last_request_at, external_user_idType of Sort Field Value

Reset user password

This feature is coming soon. Please check back later. For more updates and questions, feel free to contact our Customer Support Team.

​
Update user

Update a user profile by calling the update() method. If you want to change your password, you need to provide 2 parameters: password and newPassword. As a result, the updated user entity will be returned. You can update any other field of the user using the updateUser() method. Thus, the snippet below shows how to update a tagList and customData fields.
JavaScript
const updateUserParams = {
  customData: JSON.stringify({
    name: 'John',
    age: 31,
    city: 'New York'
  }),
  tags: ['testOne', 'tagTwo']
};

QB.users
  .update(updateUserParams)
  .then(function (updatedUser) {
    // update local user information with the data server returned
  })
  .catch(function (e) {
    // handle error
  });
The update() method accepts one argument of the object type that has the following fields:
FieldRequiredDescription
customDatanoUser custom data. Should be a String. You can convert any data types to String. For example, JSON, XML, etc.
tagsnoUser tags. An array of Strings. A tag must include alphanumeric characters only and start with a letter. There are no spaces in the tag format. For example, the “tagOne” format is correct while the “tag one” format is incorrect. The maximum number of tags is 10. If more that 10 tags are provided, an error is returned: Error: tag list should contain maximum 10 tags

​
Set user avatar

To set a user avatar, just upload a file to the QuickBlox cloud storage and connect it to the user. To upload the file to the QuickBlox cloud storage, call the upload() method and pass the fileUrl to it. The fileUrl is a path to the file in the device filesystem. Now that the file is uploaded, get the ID of the uploaded file. To connect the file to the user, set the ID of the uploaded file to the blobId field of the user and call the update() method. As a result, the user avatar gets updated.
JavaScript
const fileUrl = "path to file in device's filesystem";
const contentUploadParams = {
  url: fileUrl,
  public: false
};

QB.content
  .upload(contentUploadParams)
  .then(function (file) {
    // file uploaded successfully
    const updateUserParams = { blobId: file.id };
    return QB.users.update(updateUserParams);
  })
  .then(function (user) {
    // user updated successfully
  })
  .catch(function (error) {
    // inspect error message to check what is wrong
  });
The update() method accepts one argument of the object type that has the following fields:
FieldRequiredDescription
blobIdnoUser blob ID.

​
Get user avatar

You can also get access to the uploaded avatar of the user by calling the getPrivateURL() method. As a result, you will receive a private URL in the response. See this section to learn more about file URLs and getInfo() method.
JavaScript
const contentGetInfoParams = {
  id: user.blobId
};

// get access to the avatar that was set in user's "blobId" property
QB.content
  .getInfo(contentGetInfoParams)
  .then(function (file) {
    const contentGetPrivateUrlParams = { uid: file.uid };
    return QB.content.getPrivateUrl(contentGetPrivateUrlParams);
  })
  .then(function (imageUrl) {
    // <Image source={{ uri: imageUrl }}/>
  })
  .catch(function (error) {
    // inspect error message to check what is wrong
  });
The getPrivateUrl() method accepts one argument of the object type that has the following fields:
FieldRequiredDescription
uidyesA file unique indetifier.
