...
ServiceComb Saga Frontend
...
will be a web based application which shows all the necessary informations related to the transactions happening through Saga.
Currently
...
the Saga
...
...
module doesn't
...
provides
...
the
...
list
...
of
...
transactions,
...
providing
...
the
...
list
...
of
...
transactions
...
and
...
it's
...
status
...
to
...
the
...
users
...
will
...
be
...
very
...
helpful
...
to the users/developers in
...
development
...
as
...
well
...
as
...
in
...
production env.
So
...
here
...
is
...
the
...
proposal
...
to re-design the complete Saga Web and add all the necessary informations to the Web.
Technology Used
As
...
the
...
current
...
Saga
...
Web
...
module
...
is
...
based
...
on
...
the
...
combination
...
of
...
AngularJS
...
and
...
SpringBoot
...
App for backend and this can be ideal solution for the new Saga Frontend so we can follow the same technology.
Api Used
We
...
will
...
be
...
using
...
the
...
`/events`
...
(GET)
...
of
...
Alpha
...
Server
...
to
...
fetch
...
the
...
list
...
of
...
events
...
from
...
the
...
DB.
...
Based
...
on
...
the
...
output
...
of
...
this
...
API
...
we
...
can
...
manipulate
...
the
...
Data
...
and
...
showcase
...
the
...
Dashboard
...
as
...
well
...
as
...
Transactions
...
List.
Web Pages
...
Saga Web will
...
mainly
...
consist
...
of
...
3 Pages
...
as
...
per
...
the
...
below
...
hierarchy
...
(This
...
is
...
a
...
Concept,
...
the
...
actual
...
implementation
...
might
...
have
...
some
...
variation
...
based
...
on
...
the
...
feedback
...
from
...
community)
