AWS amplify admin queries CreateUser

Amplify does not generate AdminCreateUser by default. If you want enable AdminCreateUser query, You should do the following steps.

• Create adminQueries API using amplify. Follow this docs
• After successful creation, You can find a folder amplify\backend\function\AdminQueriesxxxx\src. We are going to edit some files inside src folder.
• Create a function called CreateUser inside your cognitoActions.js and don’t forget to export that function. Note: Don’t delete other functions

async function CreateUser(username, password, email) {
  var params = {
    UserPoolId: userPoolId /* required */,
    Username: username /* required */,

    DesiredDeliveryMediums: ["EMAIL"],
    // (optional) ForceAliasCreation: true || false,
    MessageAction: "SUPPRESS",
    TemporaryPassword: password,
    UserAttributes: [
      {
        Name: "email",
        Value: email,
      },
    ],
  };

  console.log(`Attempting to create user ${username}`);
  try {
    const result = await cognitoIdentityServiceProvider
      .adminCreateUser(params)
      .promise();
    console.log(`${username} successfully created`); // successful response
    return {
      message: `${username} successfully created`,
    };
  } catch (err) {
    console.log(err);
    throw err;
  }
}

module.exports = {
  CreateUser,
  // other functions
};

• Create an API url in app.js and import the createuser function from cognitoActions.js.

const {
  CreateUser,
  //other functions
} = require("./cognitoActions");
app.post("/createUser", async (req, res, next) => {
  if (!req.body.username) {
    const err = new Error("username is required");
    err.statusCode = 400;
    return next(err);
  }
  if (!req.body.password) {
    const err = new Error("password is required");
    err.statusCode = 400;
    return next(err);
  }
  if (!req.body.email) {
    const err = new Error("email is required");
    err.statusCode = 400;
    return next(err);
  }
  try {
    const response = await CreateUser(
      req.body.username,
      req.body.password,
      req.body.email
    );
    res.status(200).json(response);
  } catch (err) {
    next(err);
  }
});

• Add this “cognito-idp:AdminCreateUser” in Resources.lambdaexecutionpolicy.Properties.PolicyDocument.Statement[1].Action. The file you should edit,amplify\backend\function\AdminQueriesc360a2c4\AdminQueriesxxx-cloudformation-template.json
