## Transcript

[Music] welcome back this segment is going to be about building out product pages with nexjs backed by graph cms so that we can build this headless ecommerce uh platform i think you're really going to like it so let's dive in so we're going to kind of start from scratch we have an empty basically an empty directory here and we're going to create a brand new next js app so we can say npx create next app and we'll say it's like graph mess stripe check out um and yeah i think maybe the very first thing we need to do is just build a page where we can sort of list out our products um sure if that makes sense okay uh and yeah maybe then we can have like a product show page or something that has a button on it that when you click it it will create a checkout session redirect to checkout allow you to purchase and then maybe we can add some uh some web hook stuff yeah i would definitely just let's i would say we we get the um the check out let's get the data down um then maybe i have striped yes um cool and obviously load stripe as well and then because there's a few different elements to this there's the the actual data fetching and building the the pages in nextus then there's also the uh api roots element right because we have that server side requirement um to create a check checkout session with stripe we have to do that on the on the some kind of server environment um so thankfully nextgs has api routes where we can just quickly add a service function to take care of that so i think let's get the data down bill a few you build some product pages and then um yeah i'd stripe check out sounds great oh all right nice okay so we're up we're up and running here we've got pages index.js that we want to go edit all right so i think we can drop into here and maybe we can just delete everything that came with with this new app cool and then yeah so i think we want to we want to like fetch products right as like the very first thing um so maybe we need to like yarn add um is it graphql request yes we're gonna need yes you're gonna need some kind of library or some kind of client to fetch data now because we're because we're probably going to use nextgs kind of data fetching primitives whether that's get server-side props or get static props we don't really need a fully fledged graphical client for the cache aspects we can use something like like graphql requests that you've added okay it's essentially um it's just kind of a a wrapper around fetch right um which interestingly you can just use fetch um with gokul a lot of people don't know that then you you have to like um it's just simply a post request right with kind of like a post request and the body is kind of um just the query is a string stringify version of the query okay um see yeah a lot of people don't don't know that um but you know you get one thing with using something like graphql request is that you get the kind of semantic sugar that um it brings by using graphql so you can use the kind of graphql tag to get a nice um nice indentation on your on your query and things like that so there are benefits to that so yeah i think the way this works right is we just pass it um so from from graph cms yeah uh here so i'll go ahead and get the okay you've got the you've got the link i think it's settings api access this thing yeah i've dropped that in there oh perfect oh wow okay nice um uh okay cool uh and then yeah so then we want to like if we were to just do the same query that you ran from the explorer it would be something like uh maybe products is away graph cms.request and then we just pass in kind of your whole your same your same query right so we would say like products name slug id price like all of that would just go kind of like there and then we should have access to products um that's yeah it's like that easy right like you just gotta like throw in a couple packages and then write a write a little query and then uh yeah exactly you got some json then then the phone begins with the json right okay um yes what's interesting is you've kind of put the you know you've written the query inside of um the react component [Music] which is fine um that would essentially run client side um so on on page load it would run so obviously nextgs has these nice um data fetching primitives or apis for us and you're writing one there against that props okay so that'll essentially run yeah so that that query would now run at build time and build those pages or build that page uh with that data statically for us yeah cool so yeah so this would run this runs at build time not at or this runs server side not client-side because we're we're just taking advantage of this um helper that next gis gives us is that right yeah that runs that runs a build there is a get service side props as well okay okay that that is a server-side request um which has also has its benefits but in this case of building product pages like this where we're not necessarily expecting data to change massively right the speed advantage of building these pages ahead of time is actually much more beneficial so i would say get started props is probably the right uh the right functional fetch and function to use here okay perfect and then now our like we will have access to products because these um like our component that we're exporting here this react component like products will be passed in as sort of like a static json blob on the client when it renders right and then we can use that yeah so inside of get stack props you know we've made our um our query to graph cms and products has been returned and then inside of that function we're actually returning um you know returning a props object and passing products inside of there and what that means is that then that products object is available to us inside of the the props of the actual function component um so yeah at that point you have you'll have access to the products uh it'll be an array okay so then we can do something like this right where we restructure all the stuff from the product and then return like a i don't know uh something maybe just to start let's see if we can get the names to render right yeah so what what happens is although um it's like props in a production build run the build time um this will actually run each time you load the page and when using your next dev okay when you're in practice are you are you seeing like get static props or get server props more commonly used in my use in my usage definitely get started props um because as i said get server side props does have use cases um you would generally use that where perhaps data is more dynamic and so you have to think get service out props that's going to be run each time the page is requested or somebody hits the page that that they're going to it's that's gonna that query all that uh get service out props function is gonna run and it's gonna return the latest data at that time so essentially each time you're it's running on the server and then serving up that generated html from the cdn whereas we've got static props is you're building the html ahead of time serving that statically on a cdn and each person each time that's hit this is getting served the same html so i think in a lot of the work that i'm doing get started props with combined with get static paths and we'll we'll come to that those are the the the two that i'm using most often okay cool it looks like it worked like we're seeing some names here yeah so we're fetching data and putting it on the screen that is like the the story of web development right um so yeah all right we just call it our day now we're done yeah uh should we make it we should probably make this a link right um i think there's like a next thing or is it next link yeah yeah we give it we give it an href right we're saying we don't have to like name this anything different than a normal a tag and the href would go to somewhere like uh product slash and then maybe the slug so that's kind of why we used we're out of the slope to the um to the scale i guess for for prettier page paths urls using a uid um so yeah we'll link it to the product page now so i guess we need to build those okay yeah so yeah if you you can see when i hover at the bottom this would go to like products slash snapback cap because that's the slug right same thing with the hoodie also it kind of got a little gross but just keep it easy keep it easy here give these things some space all right so then um yeah so if we go to pages now um i guess we have to create like a new directory called products and then yeah this was a little weird to me but you you call it um you use square brackets and you say slug.js is that right yeah so what you're doing here yeah is essentially using kind of the file system to declare dynamic routes um so by creating this slug file with the square brackets you're essentially stating that slug is a dynamic parameter and it's going to be used to build um a sub directory of pages uh inside of products so you would use this kind of dynamic routine file system in pair with get static paths in next year's okay what that does is you actually you'll see i want all of my products from my remote cms and then for each product inside of that build this page essentially right okay so you use get static paths with get static props um so do we we i guess we have to probably export a uh get static get static paths and get static like we have to do like uh get static paths and we have to do get static props right in this file exactly okay so let's do let's do that yeah so with get static paths you're generally just fetching the data to build the path in this case the slug okay so that's going to be very similar to this i'm just going to like yeah copy might be worth kind of exporting that graphical client just to its own you can just import i can see that um yeah i wish uh this editor would not lose the graphql or like the query the query formatting but it is what it is uh yeah um so what you can do to actually counter that is actually use the graphql tag so you can do like gql something like that okay i think it's this from [Music] gotcha okay yeah that's what i mean so then you get the um so if you basically kind of it's kind of syntax highlighting for a graphql nice oh i see i see now it's yeah okay now it's not only formatted nicely it's syntax highlighted too cool yeah it's a lot easier when you start doing more complicated things so if you write if you wrote like a query like this where you might have a variable yeah you can see what i mean like the actual syntax highlight is is much more beneficial there okay yeah let's do that with getstatic props because that's going to be a little bit more complex right like we'll have x4 async um get static props and this one is it's more complex because we have to like get a specific one right i guess this is this takes in params maybe and then uh yeah or they come in sort of like this so gets get started paths returns uh the return statement is a little different there it's actually going to return a a params object sorry a paths it's going to return an array of paths or a paths array and inside that um it expects params so the slug in that case okay yeah and and then this is going to be just going to say like uh grams slug like that exactly okay cool and then i've seen i've seen this fallback uh false what does this part do fall back false yes you you have to provide the fallback key and what that does is it's essentially so it's gonna tell nextgs whether or not to fall back to rendering this or building this page dynamically so for example if i was to write a query up here for example that only returned three products of the five in my catalog and somebody went to the path for one of those products that wasn't built if fallback uh is there fallback is true and that will essentially then go off and rebuild that uh on the fly whoa okay gotcha so say for example you have products one through five i've written a query that's queries for products one through three and we build static pages for those with get started profs props if somebody then went to products slash five using fallback true would actually go off and build that page dynamically so it would run the same request uh the same get static props request and build that page on the fly and then that would be served uh in the cdn to everybody else um down here i think we just say like away graph uh cms dot um request i always want to say fetch uh yeah instead of request it's like uh yeah it's it's yeah i guess yeah i mean they've they've probably it is essentially a semantic wrapping around the request library i guess yeah or fetch libraries so it's probably for a while then here we want we want like a single product but we can't just say product or we can't just say like product where because we want to pass in like params right so we have to define a new query is that right yes you'll need to to write a query like you are and then actually kind of define the graphql variable like so yeah and then that will be available to you and then the dot sign is a graphical variable right and then that that like ties to something down here right where you say like or actually this is we want all of these to be slug right um yes we're going to find by slug yeah that may be string type yeah yeah so the second argument so in the graphql request um function uh the first argument is the query or the mutation and the second argument is is the variables uh so yeah that's exactly right okay cool and then i guess on this page we probably want name uh slug price images is that uh images is gonna be something like like that right to query the sub like the asset is going to have a url property is that correct that's right yeah so when there are subfields like so you you kind of yeah you have to um use the hash or the essentially and specify the subfields um so url will be useful um if we're going to use the next image component probably also want the width and the height of each asset all right i'll get the idea as well just because um sure you know react uh expects oh too sorry the idea of the images oh because yeah it's gonna want um because if we bump over those react expects a unique key so it's i always just ask for the id because i know it's there okay cool so then this this is a git static prop so this one returns props right return yes switch points at product something like that and then this whole thing is going to export default and then this is going to get a product uh yeah like that and then yes the outcome of get static props is is available inside of your react functional props functional component probes okay so let's see if that is doing anything yet and uh graphql is not a function uh it's that's my fault it's okay i think it might be um the import gql from graphql maybe no it's it's yeah it's that but from there oh is it okay yeah oh okay maybe this gql thing can we just like see if if we remove that that helps i know that shouldn't matter but query product page query pass and slug are we is params is this param slug for sure or is that going to be nested somewhere some other way there okay so now we see test okay so then change if we change this to is that name okay it's working i don't know what happened that was weird actually no we changed gql uh i think i think what it might have been was that we were exporting an async function here okay also they prefer to kind of do okay cool so now we've got like something showing up on the page um can we yeah i would love to see some of the new next.js image stuff so um i haven't i haven't worked with this before is it it's just an image tab the image tag that comes from from next yeah so it's a [Music] next image here it's just a component and it's essentially a drop-in replacement for the html element issue an image element um so it accepts very similar props src width height um but will kind of bring a lot of progressive enhancement with it lazy lawn adaptive uh asset loading depend on screen size that kind of stuff okay should we pull off like the very first image of the product yeah they've only got there's only one so i've only added one for each product so we could just i guess you could just map over it or you could you could just kind of destructure it if you want yeah that yeah that'll work okay and then this is like that url right and then i would have done that if you were kind of you could have done that if you were mapping over the product images over here yeah um i think that would have been more readable um yeah so i think i know the issue here um the issue is gonna be essentially we actually have to do a bit of configuration for next image to work okay in the root of the project we just need a next.config.js file and just do a module exports and it's image i believe could be images and it's like domains um which is an array and then i think it's our cds media.graphcms.com so that's essentially saying we're safe to load assets from this this url this url okay i see nice yeah okay so it's good to see if i guess it's good to kind of uh safe safe list them allow them sure and then i saw like that we could specify device sizes and image sizes are those going to like kind of work out of the box does it have some defaults that will yes there is a default configuration that will apply and it's kind of the most common kind of breakpoints you would expect so yeah those we haven't overwritten those just by kind of adding this um this config parameter um those those defaults will still apply so you don't need to worry about that so much i think i did this import wrong this should be like this maybe yeah that's right yeah mix that up like every single day i mix up like yeah yeah it's that's yeah that's a default expo boom product page with an image nice okay beautiful look at that logo it's so pretty i want this hat i know i don't even have that hat i have to go i might have to go buy from the swag store right after this you know when it's uh i actually need to enable the fulfillment yeah doesn't actually do anything yet uh we just kind of set up with test uh test keys of stripe we went back into graph cms like is this this height and width i assume is set in graph cms yeah yeah so that's just the the metadata of the image so let's just pull from the the actual asset oh got it that's i don't have to specify that at all it's just kind of pulled from the the image details i don't i don't really know enough about images to okay but all right so that's how you can uh build some product pages out we're going to go into the next section here the in the video that follows this we'll show you how to redirect to stripe checkout i think you're really going to like it
