Re: OODT NodeJS File Viewer

Thanks for the PR,
I’ll file some Jira issues later to give us some stuff to work on. We need
to figure out ways to hook up the components that aren’t hard coded etc,
eradicate CORS issues and so on.
I’ll wait for Breno’s code to land first though, then hopefully we can come
up with a unified solution to allow generic component configuration.

Hi Gimhana,
Seems like you can use Apache CXF itself to run your services [1]. With
that approach, you can bypass the requirement of jersey. If you need jersey
as the client for testing the REST APIs, you can use RestEasy [2].
Those are just two alternative approaches I found out. What do you think?

Re: OODT NodeJS File Viewer

Hi all,
I started to implement the *Product List view* component and find below the
the tasks I suppose to do.
- Implement separate REST APIs for File Listing. getFirstPage ,NextPage
etc. This is for enabling pagination support.
- Write Unit Tests for Both JAX-RS Resources and newly implementing
Web-services.
At the moment I tested the web-services using jersey framework. But after
having a offline chat with @Imesha Sudasingha <im...@apache.org> figured
out that it should have to be replaced due to licencing issues. Have any
thoughts on this?
Thanks and Best Regards,
Gimhana

Hi Tom,
The prototype has lots and lots of remaining work as you say. I just rushed
to obtain a working thing. Sorry about that.
For the custom styling support, can't we use something like
https://www.styled-components.com/.
Thanks and Best Regards,
Gimhana.

Thanks for reviewing the component. I just tested Breno's work[1] and after
testing what I understood was, both the components facilitate the same
functionality w.r.t File Manager API point of view. Further, I found some
minor packaging issues with that component and hence it is not working as
expected as an exported NPM module in a standalone React App. So the
combination of two components is not necessary as I believe. Please correct
me if I'm wrong :-)

+1. Good idea. Also, we can create a proper guide for building and
extending the components with the template prototype. In that way, the
community can easily understand the process and then they can enhance the
template as well.

Shall I start the process :-)

OODT NodeJS File Viewer
Posted by Tom Barber <to...@spicule.co.uk>.
Hey Gimhana
I took a look at the NodeJS component you created, its a pretty cool
prototype. I’m excited to see where this can go. I know Breno knocked up a
basic Filemanger list view so we should try and combine the two!
Thanks
Tom

Hi all,
I have started to develop a sample of React Plugin for File Manager
component [1]. It supports the latest ES6 Syntaxes. Developed using
web-pack4 and babel7.
At the moment it provides Reusable component for product information
retrieval.

Thanks and regards,

Re: Introducing My Self to Community
Posted by Gimhana Nadeeshan <gi...@cse.mrt.ac.lk>.
Hi all,
I have started to develop a sample of React Plugin for File Manager
component [1]. It supports the latest ES6 Syntaxes. Developed using
web-pack4 and babel7.
At the moment it provides Reusable component for product information
retrieval.
[1] https://github.com/NGimhana/oodt_fm_plugin
Thanks and regards,
Gimhana.

Re: Introducing My Self to Community
Posted by Gimhana Nadeeshan <gi...@cse.mrt.ac.lk>.
Hi Imesha and Tom,
Thanks for the extream support and the guidance you provided throughout the
whole period by sacrificing your valuable time. As a beginner to OODT I
learned a lot from both of you. Without your support, it won't be an easy
task. That experience is really worth. It's an honor to have mentors as you
guys. :-)
I submitted the final proposal for GSoC 2019 and If I am lucky enough I may
get selected. However, I need to be a part of the Apache OODT community and
hence I already started my proposed implementation in my OODT fork.
Hope to be mentored by you guys in future also !!
Cheers,
Gimhana.

Re: Introducing My Self to Community
Posted by Imesha Sudasingha <im...@apache.org>.
Hi Gimhana,
Thanks for updating the proposal. Also thanks for sharing the blog post you
written.
Blog posts will be a good way to educate dev community on OODT and attract
new contributors.
Hope you have already submitted the final proposal.
Cheers,
Imesha

Re: Introducing My Self to Community
Posted by Gimhana Nadeeshan <gi...@cse.mrt.ac.lk>.
Hi Imesha and Tom,
Thank you very much for your feedback. I updated the draft proposal
<https://docs.google.com/document/d/1IHs3bSxZjUIaGqiU4FZoWC8STKe_cG6j0IdiTLISQ0c/edit#heading=h.c9v4vdg9k7vx>
with the project timeline and applied appropriate changes as you suggested.
*Proposed Design in a nutshell*
- Separate React plugin for each OODT component (FM, WM, RE, Status...)
- Each React plugin has its own server connector itself. This ensures
cohesiveness and ready-made usability.
- Individual plugins consist of several components( these components are
the operations which are provided by the plugin - eg: product ingesting,
querying... )
- For the demonstration purposes, I am planning to design some UI
interfaces also.
- Final OPSUI dashboard can be obtained by embedding all those
individual plugins.
I already started to implement the proposed design as seen on
oodt_fm_plugin. <https://github.com/NGimhana/oodt_fm_plugin>
With the knowledge I have taken while involving in Apache OODT, I wrote a
small Medium article regarding Apache OODT deployment with Docker
<https://medium.com/devopslinks/apache-oodt-with-docker-84d32525c798>. I
feel this will be a help to newcomers to understand OODT easily because I
wrote it with my own experience as a fresher. Please read and give your
suggestions and improvements to make it more beneficial. Let's make Apache
OODT more success and community friendly. !!
Cheers,
Gimhana.
