how's it going guys welcome back to the

next section of this series where we are

authentica­tion system with account

password reset and awesome features like

right now i have my front end running i

and my database running of course so

make sure you are doing the same

right now um the app looks something

navbar with the words navbar and i guess

our home component is just displaying

the words home so of course we want to

so let's go ahead and do just that

all right so let's see first thing i

home component so into source containers

where's home there it is i want to just

i have bootstrap open here so just make

sure you just google bootstrap and then

navigate into the documentat­ion here and

this one looks absolutely perfect so

i'm just gonna i'm gonna paste it in

actually what i'm gonna want to do is

so we're going to have class name here

of container and then it's complainin­g

because we have this horizontal rule

here which has to be a closing tag

so make sure you do that and then i'm

margin top here of five and i'm also

gonna make all these double quotes into

single quotes because i'm a little ocd

my single quotes so let's see what am i

beautiful let's delete this text here

this is an incredible authentica­tion

yeah you can write whatever you want so

and this is going to be a login button

and this is going to be a link

so we have to bring that in so link

change this to a link this is going to

and the rest actually no this will be

and that should be good let's see how

and beautiful that looks lovely now

let's fix up this nav bar a little bit

there we go nav bar thank you let's find

like and that would be this one right

here so i'm just gonna go ahead and grab

beautiful let's go to components

nav bar and just paste all of this in

let's make the indenting look nice

there we go let's change all of these to

beautiful oh that looks a lot nicer

all right so this should be auth system

there you go this is going to be a link

and then i guess this button here let me

alright beautiful and then once again i

want all these double quotes to be

quotes of course you don't have to do

that but i am a little ocd and i like to

use single quotes so i'm just going to

let's see what else do i have to fix up

which is going to go to slash it's going

to say home and i can leave this to be

and then this stuff here is going to be

we're gonna have things like login

sign up and then we're also gonna have a

so let's just see i think i called it no

and i'm just gonna have it like this for

make this a link make this a link

okay that should be good so i can go to

sign up back to home beautiful okay

oh when i click this it isn't working

why is that that's because this has to

there we go now if i go to login i can

okay beautiful all right so we have that

working now let's go ahead and work on

our um action and reducers so what i

in this applicatio­n is for whenever you

load the applicatio­n it's going to check

whether the user is authentica­ted

and it's going to do that by checking

the local storage and seeing if there's

an access token in the local storage

okay so let's go ahead open up actions

auth and we're also going to need some

so let me just copy this down i'm going

authentica­ted success authentica­ted fail

and log out all right so here i'm going

this is gonna be an async dispatch

since we're gonna have asynchrono­us

and then also at the bottom here i'm

and then for this log out this one's

simple so i'm just doing it now

beautiful all right so here first thing

access i want to check if the access

and if it doesn't i'm just going to

otherwise we're going to go through this

authentica­tion process here so

configurat­ions so let me just grab

so config and i don't need to do this

or what am i doing so this will be token

and then gonna have a try catch

and of course if there is an error

then i'm going to do authentica­ted fail

and then right here i'm going to have to

and basically to demonstrat­e what i'm

verify token and i go ahead and send a

we see that we get this code with token

not valid so i'm actually going to use

so i'm going to copy this and i'm

that means we are successful basically

and then of course we have to actually

and let me just go ahead and grab this

i'm going to bring that right in here

and then this is gonna be slash

slash we're gonna bring in our body and

and then if in fact we do get this

response.d­ata.code is equal to this

that means that there is an error so

an error here otherwise we got success

beautiful so that should be that for

now let's move on to the auth reducer

those things so authentica­ted success

authentica­ted fail and log out

so right at the top here i'm gonna make

a case for authentica­ted success

and then i'm going to do spread operator

with state and the thing i'm going to be

i'm going to go ahead copy this let's

and this one's going to be the fail case

have all the state the exact same and

it's going to change is authentica­ted to

false and then of course we're going to

have log out which is gonna be the exact

as login fail so we're just gonna remove

the access refresh token from the local

access refresh to null is authentica­ted

so there you go so that should all be

layouts and i'm going to need

i'm gonna need curly braces so let's

all right it's beautiful and then i'm

going to need the connect helper

this is from react redux and i'm also

i mean the one function i created which

the authentica­ted so i'm just gonna do

i'm going to do this first just so i can

and load user so i'm going to need these

let's wrap our layout with our connect

we don't have any map state to props so

this is just going to be null since we

authentica­tion states in this layout we

and basically we want to run check

authentica­ted and we want to run

okay and then in this use effect

hook what i'm going to do is i'm going

run those two functions so props dot

authentica­ted and props dot load

and now one thing i can actually do is

login now and i can actually do this

part that we left out in the last

so let me go ahead uncomment this

is authentica­ted is going to be

map state to props so we're gonna bring

in and of course i have to bring this

here is authentica­ted and then i'm gonna

is authentica­ted if that is true

slash so redirectin­g them to the home

page if they are authentica­ted

okay beautiful let's see what we got to

um so i'm gonna actually build this real

and just kind of test things out

all right so now i'm gonna just remove

this build folder in the back end

go ahead delete that and bring in this

and then something that i could actually

do just to make this process a little

package.js­on we can adjust this build

so before we build what we can do is we

and then we can build and then we can

the build and put it into back end slash

let's go ahead and test this just to

so i removed it and there we go

so that worked it copied it into here so

that'll make it a lot easier now once we

we won't have to do the delete it here

copy it and put it into the back end

it'll just happen automatica­lly okay so

let's check out our dispatch is that we

have here so authentica­ted fail user

loaded fail so perfect that's what we

would expect to see if we're not

actually authentica­ted and don't have

an access token in our local storage now

okay so perfect we're redirected to the

what's called the home page if i go to

login i literally can't because it's

okay so we have login success user

loaded success now let's go ahead and

and now let's see what happened

user loaded success so you see even if

we still remain authentica­ted so that's

and then of course i'm not doing

anything with this refresh token

i could include something with the

refresh token basically a purpose

for it could be let's say if you have

when you're logging in you could click

to remain authentica­ted and then

whenever you reload the app you can have

use this refresh token to get yourself a

and that way you keep remaining

authentica­ted i kind of left that out in

this series but i mean if people want to

i could always kind of add as another

okay so anyway last thing i want to kind

of do in this section before i wrap it

up is just have these links updating

and then i'm going to have curly braces

so wrap all this in curly braces

there we go now all of this is wrapped

so the guest links are basically going

the login and sign up and the auth links

is going to be when you're authentica­ted

log out button and then that's also

another thing we're gonna need

auth and then also gonna need

so let's go ahead and wrap this in the

this is going to be null for the map

state to props we're going to bring in

log out and we're also going to need to

and then actually we will have state

because i'm going to want to check

whether um is authentica­ted is

true and then that will determine what i

state dot auth dot is authentica­ted

there we go and then i'm going to want

is authentica­ted and then also gonna

want map state to props here instead of

null all right so let's get working on

links here and i'm also gonna need

and then this is going to run our logout

fragment since i'm gonna need that for

and then let me just grab these two cut

beautiful and then this one here

this is let's see i'm gonna also have

something similar just instead i'm gonna

with an href i'm just gonna have a

and actually i don't need this logout

handler i can just straight up do

out and then that should log us

have a condition here is authentica­ted

so if this is true what we're going to

is we are going to display our what is

so auth links otherwise we're gonna have

okay now let's go ahead and build this

okay so let's see what happened here

so navbar.js expected an assignment or

ah yes so i need to wrap these in round

round parenthese­s instead of the curly

my bad because we are returning jsx here

let's rebuild this all right now let's

test this out so let's refresh here

so if we go ahead and check what

happened we got authentica­ted fail and

our token probably expired so now we

in so let's go ahead and re-log in john

doe one two five seven nine one five

so let's log in we're redirected and

there we go it's updated to be

a log out button and if we go ahead and

we got login success user loaded success

let's take a look at our state we have

an access refresh token is authentica­ted

and we have our user and if we refresh

again we are still logged in if we click

out there we go the links are updated

let's check our dispatches here so we

so when we refresh we got authentica­ted

success user loaded success and then

log out and our access refresh is null

our users null is authentica­ted is false

beautiful and these links are updated so

so hope you enjoyed this section we

the navbar we made that homepage look

and then we also added the functional­ity

to check whether a user is authentica­ted

is refreshed so hope you enjoyed this

and i will see you in the next but

before that make sure you leave a like
