A
Hi
welcome
to
this
back
five
mini
series.
This
is
the
belly
and
you
should
talk
for
me.
I
usually
cover
one
topic
in
deep,
but
here
I
want
to
cover
multiple
topics.
I
want
to
give
you
a
broader
overview
over
this
topic,
so
this
is
a
concatenation
of
multiple,
smaller
talks
which
cover
one
aspect
of
the
epic
five.
It
will
cover
how
to
get
started
with
epic
files,
but
breaking
changes.
You
may
expect
bigger
features
like
persistent
caching
of
module
affiliation,
but
also
smaller
improvements
like
optimizations
or
other
features.
I
hope
you
enjoyed
watching
C's.
A
So
how
to
get
started
using
the
pick
five,
and
so,
if
you
currently
install
that
pick
fire
epic
from
NPM,
you
will
get
the
stable
version
and
stable
version
of
epic
four,
and
if
you
want
to
get
the
latest
a
replica
version
beta
version,
you
want
to
use
the
next
tech
on
NPM
and
instead
of
via
these
commands
from
NPM
to
get
started.
Using
that
take
five,
you
may
want
to
it's.
A
migration
guide
about
epics
I've
make
migration.
A
A
If
you
want
to
know
more
than
there's,
this
changed
work
people
which
listen
of
useful
information
about
details
like
what
which
just
has
been
added,
what
it
just
has
been
changed:
breaking
change
all
the
bacon
changes
or
the
details
about
little
changes
and
changes
to
the
defaults
into
configuration,
changes
to
creation
and
api's,
or
internal
changes
for
plugins
and
Ladas,
and
much
information
in
this
vehicle
and
lady.
We
want
to
move
this
change
talk
to
the
official
documentation,
but
for
now
it's
in
this
temporary
people
will
now
ask
to
be
iterate
faster
on
this.
One.
A
Major
breaking
change
in
epic
5
is
that
it
moved
duplicated
things.
If
you
get
interpretation
messages
in
the
pic
for
you
may
want
to
get
rid
of
them
before
upgrading
to
the
pic
files
we
also
removed
and
the
default
pulley
filling
of
a
notice
native
modules
by
default,
if
you're
using
modules
like
m,
crypt
or
utility
m,
or
all
these
note
internal
modules,
which
are
usually
not
available
in
fondant
on
the
web
in
general,
and
we
know
no
longer
polyfills
them
by
default.
You
can
opt
into
polythene
manually,
but
we
recommend
to
use
content.
A
First
modules,
which
focus
on
fondant
technology
and
web
standards
and
don't
use,
don't
rely
on
polyfills
for
not
as
models.
We
want
to
get
rid
of
this
dependency
on
the
content,
ecosystem
tools,
the
node
ecosystem
and
deathly
fountain
and
notes
appeals
more
separate,
and
if
you
want
to
push
into
this
future
in
future
this
map
pack
5.
A
There
are
few
behavior
changes
in
epic
5
regarding
supporting
new
aspects
from
new
web
specs
that
has
been
released
in
the
meantime,
for
example,
chaste
modules
they
are
suspect
now,
for
it
must
repent
equations
chasing
modules
and
if
you
used
to
using
named
export
from
Jason
modules,
this
is
no
longer
supported
in
the
news
pack,
which
only
supports
the
default
export.
In
this
case,
web
page
5
will
now
emitted
warning
if
you're,
using
the
old
spec
and
and
make
your
way
offset
and
also
say,
webassembly
accommo
step
integration.
A
Spec
has
been
updated
or
released,
which
makes
some
behavior
changes
regarding
the
assembly
integration
into
agnostic,
material
standards,
topic
5,
you
are
able
to
opt
into
the
new
spec
or
the
odds
back,
and
we
recommend
to
align
the
coat
with
a
new
spec
which
is
which
approve
for
plugins.
If
you
use
applicants,
you
want
to
make
sure
that
all
your
plugins
that
pick
5
compatible-
and
you
may
want
to
upgrade
or
plugins
to
the
latest
version,
to
get
its
support.
A
A
So
resistant
caching
is
like
normal
cutting,
but
it's
stolen
to
disk,
instead
of
in
so
currently
that
take
for
only
uses
occasion
to
make
watching
you
meant
a
built-in
watch
more
very
fast
and
president
caching
brings
a
caching
feature
to
to
this
end
allows
you
to
see
we
start
back
without
a
large
in
you
compilation,
time
so
to
show
it
em
I've
prepared
this
little
example.
A
A
So
now,
when
I
do
the
same
again
without
any
change
like
young
built
like
a
budget,
build
will
take
only
F
factor
off
this
time
and
it
will
restore
everything
from
cache
and
build
in
about
4
seconds
it
still,
which
takes
all
the
files
or
the
build
dependencies
and
everything
to
be
sure
that
nothing
changed,
and
then
it
also
compare
files
differences.
If
there
are
modifications
to
the
output
file
was
ever
a
deleted
and
we
omit
them
everything.
A
So
it
should
be
safe
that
everything
is
fine
and
the
development
build
is
usually
just
the
same
with
smaller,
bigger
files,
because
it's
not
minimized,
but
a
little
faster,
maybe
also
notice
that-
and
we
are
innovating
very
cool
names
automatically
for
for
your
channels,
based
on
the
modules
they
contain.
That's
one
part
of
the
development
experience.
Improvements
in
their
pixel
in
the
production
will
be
generate
ideas,
it
kind
of
hashes.
A
This
is
a
limitation
for
long
term
clashing
to
make
chunk
finance
change
less
often
anyway,
back
to
persistent
caching
so,
and
I
also
can
I
now
can
be
able
to
start
a
development
watch
mode
within
few
seconds
compared
to
as
a
full
build
which
would
take
it
40
seconds
after
starting
in
watch
mode
I
will
enter
as
a
in
the
more
cache
mode,
so
in
I
always
change
from
now
on
done
in
the
movie.
So
this
will
be
as
fast
as
period.
A
Then,
when
we
storm
from
the
persistent
cache
we
don't
lord
any
lower
initial
days
as
any
of
these
people
set
us,
you
need
for
your
build.
So
if
you
do
the
change
for
the
first
time,
we
need
to
put
up
like
babel
order
in
this
example
and
give
it
did
a
few
times
to
speed
up
and
also
need
a
few
iterations
to
get
to
full
speed
minutes
optimized
by
javascript
engine.
So
you
see
like
few
seconds
before.
What's
the
first
try
and
then
it
it
usually
gets
as
fast
as
usual.
A
I
found
that
many
pencils
this
example-
okay,
and
you
also
see
that
we
down
store,
is
a
persistent
cash
em
on
watch
mode.
Video.
Oh
wait
like
a
minute,
read
like
a
minute
idle
time
until
the
stores
a
business
in
cash
don't
want
to
into
it
interact
with
your
user
flow
and
want
to
keep
everything
fast.
A
So
if
you
do
a
production
build,
it
will
have
to
be
a
production,
build
with
changes
done
in
the
meantime,
and
it
will
boost
all
the
cash
updates,
a
compilation
with
the
changes,
and
it
takes
a
little
bit
longer
than
just
doing
build
without
change,
because
we
know
have
to
run
the
lower
us
to
the
minimal
occasion
of
the
changed
file.
But
in
the
end
there
is
a
built
after
position.
Caching,
even
if
I've
changed
and
I'm
missing
will
be
very
stable,
very
safe
and
it
will
always
gonna
wait
reddit
with
solid
ice.
A
Thank
you,
sir.
Here
it
probably
takes
a
few
more
seconds
to
to
build
this
like
6
seconds
compared
to
this
suite
or
to
four
seconds
and
when
I've
done
this.
This
first
time
cause
now
and
like
this
I
have
to
be
we
minimized,
because
I
change
this
file
present
in
the
casting
is
an
opt-in
feature,
so
you
don't
get
it
by
default.
You
need
to
enable
it.
We
have
some
configuration,
you
see
here
so
better.
A
My
dependencies
are
things
that
and
define
how
your
your
module
or
a
complete
completion
is
build
so
like
web
pack
version
and
also
a
configuration
epic
itself
to
build
appearances,
and,
but
you
have
to
add
the
config
file
manually
in
this
case
and
so
to
give
it
a
complication
and
third
dependencies
change
every
were
to
work,
a
fresh,
build
and
clear
the
cache,
the
form,
if
you
also
use
some
additional
logging,
usually
you
won't
that
won't
get
any
of
these
messages.
Life,
timing,
information
about
the
persisting,
Cashion
and
so
on.
A
It
would
be
silent
and
transparent
and
to
vote
won't
see
it
in
if
not
from
timing.
The
system,
caching,
is
all
the
user
builder
plug-in.
So
plugins
can
use
the
persistent
cache
API
to
stores
our
own
data
own
carry
information
like
a
zoom
in
also
a
separate
plugins.
It
tells
I
mean
epic
plug-in
and
such
as
I
left
a
plate
in
uses
as
a
epic,
five
cache
API
to
store
yeah
minimized.
Besides
and
caching,
information.
A
A
This
is
buddy
useful
if
you
don't
use
all
the
antibiotic,
but
through
shaking
yes,
an
example
is
basing
to
shaking
on
the
top
left
top
right
and
you
would
see
the
production
version
of
the
bundle,
and
here
we
would
say
there
is
a
development
version
of
the
pandal
first
thing
you
may
notice
is
that
we
started
to
use
ever
function.
Yes,
we
can
await
a
higher
level.
I
one-time
quote
by
default,
but
this
is
controllable
by
a
second
option.
So
if
you
disable
this,
it
set
it
to
M
most
version
5.
We
will.
A
He
was
function
instead
of
function
s,
but
we
give
it
in
the
more
demised
way
so
better
to
shaking
works
as
a
user,
and
with
this
little
past
info
options,
you
were
able
to
obtain
more
information
about
fishing.
So
you
this
isn't
in
the
development
bundle.
They
are
all
the
exports
understood
and
if
they
provided
used
and
also
renamed,
the
renaming
is
a
little
bit
changed
for
long
term
caching,
so
we
don't
generate
ABCD
and
by
default.
A
Instead,
we
can
await
rehash
the
name
and
gonna
write
a
shot
down
the
fire
this
better
for
for
don't
I'm
cashing
because
they
don't
change
it.
So
often
the
basic
twittering
still
works
at
the
import
ever
and
only
Apple
is
injected
in
is
exported
and
all
other
things
would
be
clocked
by
minimizer,
and
you
see
it's
when
marilla
concatenated
would
be
really
optimized
abundant,
be
enabled
and
deeper
nesting
of
export.
So
if
you
have
an
example,
they
are
Buicks.
A
Now,
if
you
really
explore
this
module
this
in
names,
but
epic
and
V
exports,
namespace,
abject
and
then
use
it
was
a
deep
pass
to
suspend
on
export
and
vector
could
be
able
to
handle
this
denied
exactly
the
same.
Output
code
in
production
and
development
would
be
either
who
practice
keep
information
from
exports
and
autumn
angle,
or
all
day
as
on
this
side,
so
it's
yeah
so
potted
and
the
next
example
is
in
a
graph
optimization.
In
this
case
we
use
some
functions
and
import
some
exports
and
this
exports
I
only
used
in
some
functions.
A
So
in
this
case
we
exports
a
gate,
function,
just
say:
F
function
and
the
f12
misses
things
well
export,
but
the
test
export
doesn't
use
it
at
all.
So
if
you
only
use
the
test
export
that
they
will
be
able
to
analyze
it
and
will
be
able
to
observe
this
12v
export
from
the
Panda
in
disguise,
nothing
is
used
for
module.
A
If
I
use
get
instead,
it
will
be
using
sloppy.
The
next
thing
we
optimize
is
some
kind
of
secret
feature
is
life
and
it
was
like
you
know:
comments
modes
I
have
the
same
module
as
commands.
Us
here
was
like
assign
exports,
module,
exports
or
also
defining
property
lenses.
We
have
support
more
complex
of
cases,
but
not
everything
is
to
the
poet
the
common
chess
is
basely
only
supported
in
and
off
sometimes
may
so.
A
Only
if
it's
statically
analyzable,
you
basically
support
common
chase
tree
second
in
this
manner,
so
here,
and
you
would
see
that
and
epic
will
drop
all
unused
to
exports
in
Comanche,
s2
and
Mongol
exports.
The
same
they
ask
like
in
my
script
modules
and
it's
all
just
and
available
to
require
em
some
common
traits
modules
and
use
exports
from
there
in
this
case,
and
it
could
also
optimize
it
with
detect,
which
ones
I
used
same
is
available
for
the
interrupt
logic.
A
If
you
require
a
equipped
module
and
only
use
some
exports
of
them,
this
block,
as
you
sure
we
also
edit
to
shaking
for
Jason
modules,
to
striking
from
this.
So
if
you
only
use
some
properties,
like
version
or
some
D
properties
like
dev
dependencies,
we're
back
on
this
pick
up
Jason
Tata,
we
will
optimize
Jason
and
drop
all
unused
properties,
mangaloray
properties,
if
say
only
used
in
statically,
analyzable
way
and
Betty.
Only
in
injector
values.
A
You
are
really
using
in
the
bundle
we're
also
using
adjacent
path,
optimization
for
faster
one-time
execution
of
Jason
Tata,
and
recently
we
added
another
optimization
of
manually
metric
comment
for
with
a
generic
important
players
can
specify
which
exports
I
used
from
the
dynamical
imported
or
you'll.
If
you're
only
using
up
export
or
the
default
export,
and
it
would
be
possible
to
specify
such
a
thing
and
in
at
one
time
it
will
generate
upon
the
compiler.
A
So
if
you
would
build
present
profile
enabled
it
will
show
you
life
and
the
current
plugin
it's
working
on,
and
those
will
give
you
some
timing,
information
about
each
step
and
it's
been
in,
and
it
will
be
very
useful
to
investigate
your
builds
and
see
what's
taking
a
long
time
in
a
very
basic
way,
without
anything,
I
will
profiler.
So
here,
in
this
case,
we
see
tell
the
plugin
takes
a
lot
of
time,
but
it's
expected,
but
you
can
also
see
for
details
for
some
internet
plugins
and
so
on.
A
Another
barrier
to
get
more
insight
into
that
big
completion
process
is
the
locking
system.
So
we
have
a
cool
locking
system
which
can
be
enabled,
or
the
output
of
the
lock
can
be
enabled
with
some
states
option
like
locking
the
boss
and
they
could
all
repose
information
about
them
and
reflect
x5.
We
add
a
lot
of
interlocking
timing,
information
to
the
log
output,
and
so,
if
you
do
something
like
that,
you
will
get
a
lot
of
timing.
Information.
A
Froy,
that's
within
the
compilation
before
different
plugins
and
so
on,
and
you
could
even
enable
debug
mode
for
logging
forget
even
more
nothing
information,
the
Big
Five,
we
know
exposed
tidings
from
their
pack,
so
we
can
await
our
own
typing's
from
from
our
source
code
and
expose
them
as
typing
technologies
for
typescript.
So
if
you
isn't
apps
tip
or
just
using
our
script
or
users
to
encoder
any
editors,
it
supports
typescript
typings.
A
You
could
add
some
annotations
to
do
that
by
configuration
and
like
exists
in
in
bacteria
stocks
and
forever
script,
and
it
really
gives
you
cold
completion
and
information
and
descriptions
for
all
your
configuration
I.
Have
this
allows
me
to
write
like
experience
and
information
about
all
the
experiments
like
enable
MDS
whatever
it
also
allows
you
to
tap
check
your
configuration
and
whole
system
also
works
for
plugins.
If
you
apply
to
plug-in
you
get
all
API
of
their
peg
as
good
completion
and
validation.
A
The
pick
five
supports
advanced
configuration
for
empty
points.
Here
is
your
example
where
we
have
to
enter
points
like
chord
at
men
and
normal
import
of
modules.
There
any
point
should
contain
is
yeah
specified.
We
are
its
import
property
and
this
object
allows
it
once
configuration
like
you
can
configure
a
separate
file
name
of
item
template
for
this
I
like
C,
core
or
C
core
content
head
or
whatever,
and
you
also
can
specify
a
separate
library
option
and
say
this
is
a
problem.
S
teedle,
GUI
and
other
ending
points
are
exported.
As
a
library.
A
A
So
in
this
case,
we
can
use
the
depend
on
future
and
the
Pequea
quite
a
parent-child
dependency
between
his
NT
points
or
this
chance
and
in
the
end
the
core
endpoint
will
contain
us.
Libraries
and
admin
will
only
contain
debuts
of
modules,
which
are
not
already
contained
in
the
cross
way.
In
this
case,
it
would
be
really
small
and
only
contains
the
control
dog
statement,
because
libraries
are
already
on
the
page.
He
has
a
qualified.
A
Next
example,
I
was
in
his
next
feature.
We
assume
we
have
a
large-scale
application
and
we
want
to
develop
this
application,
but
a
part
of
this
application
with
separate
teams
and
each
team
should
the
ability
should
have
the
ability
to
deploy
their
work
separately
from
the
other
teams.
The
idea
is
that
at
one
time
all
the
work
of
the
teams
comes
together
and
they
sleep
together
into
a
single
monolithic
application
for
this
module
Federation
as
new
feature
and
epoch.
Five
is
go
to
hell.
We
see
here.
We
have
three
very
possible.
A
We
containers
for
each
team
and
these
three
parts
were
to
come
together
in
a
you
know:
full
application
or
Singapore
application.
This
could
be
a
model
papers
could
be
separate
or
a
post
doesn't
matter.
So
what
is
to
use
this
feature?
We
would
specify,
in
their
in
the
web,
configuration
that
we
would
like
to
use
a
model
Federation
feature,
and
here
we
would
in
the
application
we
want
to
consume
component
sleep
from
TB
and
another
component,
yet
from
Team
C
and
to
use
them
we
specify
or
Z.
A
The
parent
is
in
their
moods
and
property,
and
repick
will
make
sure
that
every
every
time
we
request
a
module
from
component
clip
of
another
component,
but
it
will
look
it
up
at
one
time
on
in
a
script
tag
that
is
Laura
at
one
time.
It's
easier
on
the
other
hand,
and
the
other
teams
would
use
the
same
feature
and
would
also
use
the
module
Federation
back
in,
but
in
this
case
a
excuse
exposed
feature
to
expose
modules
to
other
teams.
A
So
here
we
would
expose
component,
which
it
is
a
public
name
per
component,
and
if
we
would
expose
our
source
file
component,
which
is
a
basic
react
component
in
this
case,
another
team
will
do
it
the
same
way.
You
could
all
expose
more
properties
Mira,
the
tricky
part
is,
and
we
want
to
share
libraries
in
this
case.
So
if
you
don't
want
each
of
these
separate
bills
to
Lord
act
on
it
all
and
direct
them
and
loaders
and
data
functions
for
this,
we
use
the
shared
feature
of
motor
Federation.
A
So
each
of
these
compression
we
can
specify
which
libraries
of
the
build
should
be
shared.
In
this
case,
we
want
to
share
a
react
and
the
compare
clip
want
to
share
react
and
want
to
share
that
tape,
functions
and
the
another
component
lead
here.
In
this
case,
all
the
want
to
share
or
inland
really
low
models.
A
A
And
it
could
look
like
this.
Everything
comes
together
at
one
time
and
here
a
component
phone
company
from
companies
lip
another
company
and
I
could
also,
if
I
use
this
toggle
button.
Take
it
over
to
the
code.
Toggle
button
would
Lord
some
component
yeah.
This
react,
lazy
and
blot
it
on
demand,
so
you
can
also
lord
other
components
on
demand
like
I.
Usually
do
so.
Basically,
everything
behaves
like
these
are
normal
NPM
packages,
but
it's
two
on
one
time:
it's
linked
together.
A
So
here
you
see
the
application
running.
It
feels
like
a
single
page
applications
there's
no
special
object
here
to
like
iPhones
or
whatever
make
it
special
anyway.
It's
just
getting
more
duels
together
in
a
single
application
at
one
time
and
of
the
framework
unfamiliar
it
feels
like
every
call
is
just
a
single
application.
It's
all
possible
to
Lord
motors
on
the
on
demand
here.
I
call
it
some
more
tools
on
the
click
on,
as
a
button
say
usually
constraint
with
epic.
A
Is
that
any
on-demand
learning
should
only
take
a
single
amount
of
total
server,
and
this
is
still
true
with
model
Federation.
It
will
only
take
a
single
one
trip.
Every
files
from
separate
modules
will
be
run
in
parallel
for
Moodle
Federation's.
Initial
page
load
needs
an
additional
round
trip
to
the
server
compared
to
number
single
build
application
because
it
has
to
get
the
information
forms
from
the
other
separately,
builded
application
paths
and
website
information
how
to
lots
and
lots
of
files
from
from
this.
These
containers.
A
This
example
also
shows
a
few
edge
cases
you
might
run
into
so
here,
like
the
application
uses,
reg
16
and
the
component.
Let
users
react
15
in
May
2000,
so
this
is
technically
in
capital
and
by
default,
motor
Federation
would
not
bow
Russian,
so
it
will
download
to
X
16
and
15,
and
each
leopard
build
its
application
path
with
people
provided
its
own
version,
its
competitiveness,
but
for
further
components
like
react
or
angular
other
things,
it's
not
possible
to
load
multiple
versions
of
the
framework,
because
it
it's
not
for
technically
reason.
A
It's
not
possible
to
make
a
react
app
on
different
react.
Well,
that
would
get
so
in
this
case,
I
can
use
the
advanced
configuration
for
the
shared
modules
and
specify
that
react
is,
is
a
singleton
and
shared
model.
Singleton
set
model
means
it
will
only
ever
load
a
single
version
of
this,
in
this
case
the
highest
version,
and
instead
of
getting
its
own
version,
they
will
provide
them
in
warning,
said
technically
incompletely,
and
yet
you
should
look
into
wearing.
You
are
comparative.
A
Another
edge
of
case
is
here
that
we,
both
component
lips
using
different
versions
of
date,
date
function.
So
here
it's
version,
2.6
and
another
company
is
using
in
2.14
and
in
this
case
oil
and
builds
or
the
gamepad's
would
agree
on
the
highest
version,
which
is
compatible
basis.
In
this
case,
it
will
not
date
function
from
another
company,
because
it's
providing
the
highest
well
thanks
for
watching,
have
a
good
day
and
enjoy
the
conference.
