Tools to Working from home in Sri Lanka.


Working from home is getting more important in these days due to lockdowns in many countries. Following free and paid tools helps you to manage your work efficiently at home.



We all know Skype for conference calls, instant messaging with clients or chat rooms. But if you haven’t been using it for business, you may have missed out on some new functionalities. Record Skype calls to capture key decisions, and use live subtitles to read the words spoken. Easily share presentations, images, or anything on your screen during a call with integrated screen sharing. Access one skype account across multiple devices—even Alexa!



Slack is the communication tool that brings remote teams together. The platform organizes conversations into channels, which team members can join and leave, as needed, so nobody receives messages or notifications irrelevant to them. Conversations can also be had in threads, which keep messages outside of the main channel so chats don’t get in the way of main topics and projects.

Key features

• Instant messaging: Live communication between every team member for seamless collaboration.

• Statuses: Users can set availability statuses to focus on individual tasks as needed.

• File sharing: Drag-and-drop file sharing for PDFs, images, videos and other common files types.

• Voice & video calls: Voice and video calls directly from within Slack.

• Screen sharing: Allows team members to show their work to others in real-time for stronger collaboration.



GoToMeeting is a web-hosted service created and marketed by LogMeIn. It is an online meeting, desktop sharing, and video conferencing software package that enables the user to meet with other computer users, customers, clients or colleagues via the Internet in real time.



Zoom is a suite of video conferencing and communication tools designed for remote teams, virtual businesses conferences, webinars and other corporate purposes. We use Zoom for our virtual meetings, which we can use to run video and voice calls, but it’s capable of much more than this.

Key features

· Video meetings: Remote teams can run video meetings and one-to-one video calls.

· Voice calls: You can also run group or one-to-one voice calls when face-to-face meetings aren’t necessary.

· Webinars: You can also use Zoom to host webinars.

· Messaging: Team members can send messages using Zoom.

· File sharing: Share files during and outside of video/voice chats for collaboration between members.

Microsoft Teams



Teams is a chat-based collaboration tool that provides global, remote, and dispersed teams with the ability to work together and share information via a common space. You can utilize cool features like document collaboration, one-on-one chat, team chat, and more. Microsoft Teams is also fully integrated with many other Office 365 services, such as Skype, SharePoint, Exchange, and Yammer.

Team viewer


TeamViewer is a remote access software that allows desktop sharing and file transfer. It is an exceptionally secure software that does not disturb the functioning of existing firewall or antivirus in your system. TeamViewer 14 protects your data simultaneously while you are sharing your desktop screen through remote access.

– A couple of exercises based on default `init` template:

– Add few buttons and test out handlers (with `bind` preferably)

– Add a bunch of different `<View />`s



In this section, we, describe `StyleSheet` API, how it implements flexbox and how’s that different from CSS.

– Describe StyleSheet, what are available values, how it works

– Demonstrate `Flexbox`

– Mention that there are UI kits, but we are not going to use them as it’s too advanced for now

– Mention that there are cross-platform styling techniques, like styled-components one can use

– A bunch of exercises to get attendees more familiar with the styling, esp.:

– Flexbox and its properties – implement column/grid layout as presented on a slide

– <Text /> number of lines



In this section, we demonstrate basic concepts of navigation. We also brief attendees into how’s JS navigation different from fully native one. We list available alternatives as well what we will use throughout today.

– List available navigation solutions

– Brief readers into the one that was selected

– Make them aware of the API and how to think of the route hierarchy

– A couple of exercises working on current `init` template, e.g convert app to a stack, so we can push a new route



In this section, we describe lists and why they are so important in React Native. We describe available alternatives and list how’s `<ScrollView />` different than `<FlatList /> (and <SectionList />)` and when to use each.

– List available scroll solutions

– Explain when to use each

– Describe performance optimizations

– Warn about common pitfalls / issues
