I have created a sample application using dotnet core, I have also implemented web-pack for bundling angular.
My problem is the bundled file is really big, around 6MB.
Here is my polyfills.ts file
import 'ie-shim'; // Internet Explorer 9 support.
import 'core-js/es6/symbol';
import 'core-js/es6/object';
import 'core-js/es6/function';
import 'core-js/es6/parse-int';
import 'core-js/es6/parse-float';
import 'core-js/es6/number';
import 'core-js/es6/math';
import 'core-js/es6/string';
import 'core-js/es6/date';
import 'core-js/es6/array';
import 'core-js/es6/regexp';
import 'core-js/es6/map';
import 'core-js/es6/set';
import 'core-js/es6/weak-map';
import 'core-js/es6/weak-set';
import 'core-js/es6/typed';
import 'core-js/es6/reflect';
import 'core-js/es7/reflect';
import 'ts-helpers';
Here my is network status
How can I reduce the file size of the bundled file?
<my-app>Loading AppComponent content here ...</my-app> This text is showing before the component is visible, how can I speed up it?
If you are using the webpack, you need to use the command parameter p for production.
webpack -p --progress

This is my project structure. I am trying to access settings.py file from lookups.py
I am importing using following code,
import os
import sys
import django
sys.path.append('/path/to/django/project')
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'manageemployee.settings')
django.setup()
from manageemployee.apps.employee.hrmmongodb import DBMixin
from manageemployee.settings import EVENT_STORE_DICT
But I am getting the following error,
ModuleNotFoundError: No module named 'manageemployee'
It's better to use settings by importing the object django.conf.settings wherever it was needed instead of the settings file itself as you are trying,
Example:
from django.conf import settings
if settings.DEBUG:
# Do Something
So in your use case:
from django.conf import settings
EVENT_STORE_DICT = settings.EVENT_STORE_DICT
# Do Something
Note that django.conf.settings isn’t a module – it’s an object. So
importing individual settings is not possible:
from django.conf.settings import DEBUG # This won't work.
You can also find the detailed information in the Docs
My bot.py 's code is :
import discord
from discord.ext import commands
import random
from discord.ext.commands import bot
import asyncio
import requests
import os
client = commands.Bot(command_prefix = "!")
.. Command's and stuff..
bot.run(str(os.environ.get('DISCORD_TOKEN')))
My requirements.txt consists of :
discord.py
requests
My Procfile consists of :
worker: python3 bot.py
I followed all steps to deploy through git and it successfully got deployed but still it's not online.
You bot doesn't go online because of your os.environ. It doesn't have any get method since it's a Mapping object. Here's how you use it:
bot.run(os.environ['DISCORD_TOKEN'])
PS: you have some unecessary imports, like from discord.ext.commands import bot. You should only import what you need (eg. from os import environ instead of import os).
I am trying to create a very simple Katalon test case that opens Firefox, goes to given URL and clicks a button to download a file. I have set up Desired Capabilities according to the Katalon documentation (https://github.com/katalon-studio/docs/blob/master/pages/katalon-studio/docs/introduction-to-desired-capabilities.md) but with no luck. When I try to download a file prompt shows up and file is not downloaded. How can I disable the prompt and download the file immediately instead?
Software versions, source code and screenshots below.
Windows 10, Katalon Studio 7.2.1, Mozilla Firefox 72.0.2, Selenium 3.141.59
import static com.kms.katalon.core.checkpoint.CheckpointFactory.findCheckpoint
import static com.kms.katalon.core.testcase.TestCaseFactory.findTestCase

import internal.GlobalVariable as GlobalVariable
import org.openqa.selenium.Keys as Keys
WebUI.openBrowser('https://file-examples.com/index.php/text-files-and-archives-download/')
WebUI.click(findTestObject('downloadCsvFileButton'))
For Chrome the default setup of Desired Capabilities in Project Settings works fine, but for Firefox I had to do some workaround to make it work.
So, I found this topic https://forum.katalon.com/t/opening-firefox-with-a-specific-non-anonymous-profile/12012/15 and #kazurayam 's reply helped me to create a script that initializes WebDriver which I call before each test case:
import org.openqa.selenium.WebDriver
import org.openqa.selenium.firefox.FirefoxDriver
import org.openqa.selenium.firefox.FirefoxOptions
import org.openqa.selenium.firefox.FirefoxProfile
import org.openqa.selenium.firefox.ProfilesIni
import static com.kms.katalon.core.testobject.ObjectRepository.findTestObject
import com.kms.katalon.core.webui.driver.DriverFactory
import com.kms.katalon.core.webui.driver.WebUIDriverType
import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI
import internal.GlobalVariable as GlobalVariable
WebUIDriverType executedBrowser = DriverFactory.getExecutedBrowser()
switch(executedBrowser) {
case WebUIDriverType.FIREFOX_DRIVER: // "Firefox"
System.setProperty('webdriver.gecko.driver', DriverFactory.getGeckoDriverPath())
FirefoxOptions options = new FirefoxOptions()
options.addPreference('marionette', true)
options.addPreference('browser.download.folderList', 2)
options.addPreference('browser.helperApps.alwaysAsk.force', false)
options.addPreference('browser.download.manager.showWhenStarting', false)
options.addPreference('browser.download.dir', GlobalVariable.downloadPath)
options.addPreference('browser.download.downloadDir', GlobalVariable.downloadPath)
options.addPreference('browser.download.defaultFolder', GlobalVariable.downloadPath)
options.addPreference('browser.helperApps.neverAsk.saveToDisk', 'application/download, application/octet-stream, text/csv')
WebDriver driver = new FirefoxDriver(options);
// let Katalon Studio to use the WebDriver created here
DriverFactory.changeWebDriver(driver)
break
default:
WebUI.openBrowser('')
}
Note to others, if you want to download different file types you have to specify all the required the MIME types in ‘browser.helperApps.neverAsk.saveToDisk’ preference. A list of MIME types can be found here:
https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Complete_list_of_MIME_types
Additionally, if the file is PDF you have to add one more preference:
options.addPreference('pdfjs.disabled', true)
As suggested I installed using
npm install #reactivex/rxjs#5.0.0-beta.11
I can import almost everything this way:
import { Observable, Subscriber } from '#reactivex/rxjs';
but not WebSocketSubject. I've tried:
import { WebSocketSubject } from '#reactivex/rxjs';
import { WebSocketSubject } from '#reactivex/rxjs/observable/dom';
... and many other variations.
dom is not a file, but a folder, so there will nothing to import :)
Try this one:
import { WebSocketSubject } from '#reactivex/rxjs/src/observable/dom/WebSocketSubject';
The import will give you the TypeScript source file, but I would recommend installing rxjs#5.0.0-beta.11 rather than #reactivex/rxjs so you can do this:
import { WebSocketSubject } from 'rxjs/observable/dom/WebSocketSubject';
The above import will give you the .js file, not the .ts file. Autocompletion and all the good TypeScript stuff will still work, because the package has the .d.ts files!
One more tip: If you having problems finding the correct import path:
Go to node_modules/[<organization_name>/]<package_name> (the organization name is optional, they all start with #).
This is your starting point for all imports, from there you can append any folder/file path to the [<organization_name>/]<package_name> and the import should work.
But if you only point to the import statement to [<organization_name>/]<package_name> Typescript will pick up the real path to the import file from the main property of the package.json. Which in the case of #reactivex/rxjs points to index.js and that file again will do a require('./dist/cjs/Rx'). So when you do #reactivex/rxjs the path gets resolved to node_modules/#reactivex/rxjs/dist/cjs/Rx.js.
Hope this explaination wasn't to confusing, but the path resolution sometimes can be :-x
I am tying to do a simple map reduce function in Hadoop 2.3.0 using the org.apache.hadoop.mapreduce API and yet when I try to to run it I get the following error
org.apache.hadoop.mapreduce.lib.input.FileSplit cannot be cast to org.apache.hadoop.mapred.InputSplit.
Since what I call in the mapreduce function I am using is this
import org.apache.hadoop.fs.Path;
import org.apache.hadoop.conf.*;
import org.apache.hadoop.io.*;
import org.apache.hadoop.mapreduce.*;
import org.apache.hadoop.mapreduce.lib.input.FileInputFormat;
import org.apache.hadoop.mapreduce.lib.input.TextInputFormat;
import org.apache.hadoop.mapreduce.lib.output.FileOutputFormat;
import org.apache.hadoop.mapreduce.lib.output.TextOutputFormat;
I have no idea why it keeps using the old API, is there some configuration file I have modify?
Try using hadoop dfsadmin -refreshNodes command to refesh the nodes. So that it will fetch new API.
