Advanced analytics Arc XP offers comprehensive analytics that enables companies to better target content and commerce for higher conversion rates, thereby understanding their audience.Although Arc XP Commerce is a great fit for businesses with complicated needs, it comes with high Arc XP pricing and calls for significant technical knowledge to run and maintain. Small and medium-sized companies with limited resources find this less ideal as a result.

garnering space at grocery chains, even at the more principled ones such as Whole Foods, often requires 6-figure slotting fees and the ability to produce at massive scale.

The most telling real-world results came from the final stock count. For example, no Felix product is more beloved than its best-selling meatballs, yet with customers encouraged to make decisions on climate value, they remained on the shelves, whereas Felix’s new, plant-based meatball alternatives had sold out. Shoppers had learned that the classic dish they had eaten since childhood might not, after all, be the best option for their own children’s future.

The way in which shoppers were presented with practical climate information was repeatedly commented on as a brilliantly simple idea that people felt ought to be the norm in food retail. Plus, we saw repeat visits – parents so impressed by the concept’s educative value that they came back a second time with their children.As one shopper shared: “I didn’t expect this when walking in. The visuals with the three different bags explained everything so well. I learned so much more compared to, say, a lecture.”

The results told us Felix’s demographic really wanted to shop for climate-friendly food brands, but found the sustainability information too confusing and – perhaps as a result – believed sustainable grocery shopping to be too expensive.Our strategy was clear: Give shoppers better information on the climate impact of Felix products and, in the process, demonstrate how easy it is to make climate-friendly choices when products are clearly labelled. We called it The Climate Store (Klimatbutiken) – the world’s first grocery shop in which the ‘price’ of food would be based on its carbon footprint.

I personally abstract everything away into stores. Stores are amazing. With everything I mean things like fetch, Worker or WebSocket.

export const fibonacci = function (n, initialData) { return readable( { loading: true, error: null, data: initialData, }, (set) => { let controller = new AbortController(); (async () => { try { let result = await fibonacciWorker.calculate(n, { signal: controller.signal }); set({ loading: false, error: null, data: result, }); } catch (err) { // Ignore AbortErrors, they're not unexpected but a feature. // In case of abortion we just keep the loading state because another request is on its way anyway. if (err.name !== 'AbortError') { set({ loading: false, error: err, data: initialData, }); } } })(); return () => { controller.abort(); }; } ); };

Yes I love stores.

const unsubscribe = errorStore.subscribe(value => { if (!value) { return } error = value errorStore.set() })

All my stores also have a defaultValue property and reset method

I've said it multiples times and I say it again: in Svelte stores solve all your problems and I love them so much.

I ended up writing a custom store that "buffers" sets for both a small time interval and ensuring only one async action is in flight (and triggering an extra round of async processing if a set was seen after the last async action was launched).

In effect, the $ syntax we've seen above will actually setup a subscription to the store. And the subscription will be cancelled when the component is destroyed. If the store is subscribed by multiple components, the store will be disposed only when the last component unsubscribes (it will be reinitialized, if a new subscription is made). This is very handy to manage the lifecycle of disposable things in your code.

lifecycle is also managed automatically by Svelte

(And we've covered 75% of the store topic... They're efficient, to the point... And simple!)

In order to use this, we need to use a little more advanced readable store. Here's your example updated for this:

In your Svelte component, you can then use your store with the special $ prefix syntax, to access the value of the store ('cause the temperature variable is a reference to the store itself, it's just a mean to our end, the result we need is the value):

// our temperature is now a store with initial value 0 const temperature = writable(0); // now we don't need to change this function, the change will be propaged // by the store itself const getTemperature = () => { return temperature; }

Here's how we would rewrite our callback example with a store instead:

Same as our callback example, except they offer a handful of other very useful tool (like computing derived values from other stores), and also a slick syntax in the Svelte component.

Stores are essentially some kind of simplified streams (or Observable as they're called in ES), that is they represent a value over time.

QueueStore

For me however, things get really interesting with the creation of “custom” stores. The creators of Svelte were/are obviously well aware of the power and flexibility of these stores and have provided a simply interface to adhere to. Basically, any object that implements the “subscribe” method is a store!

One of the (in my opinion) most useful components of the Svelte library is that of “stores”.

What I like is that currentUser isn't a value, it's a store, and therefore you have full control over how you deal with it.

Talking of context, that's much closer to the approach I take with Svelte and use a writable store.

The only solution that I can see is to ensure that each user gets their own set of stores for each server-rendered page. We can achieve this with the context API, and expose the stores like so: <script> import { stores } from '@sapper/app'; const { page, preloading, session } = stores(); </script> Calling stores() outside component initialisation would be an error.

The more I think about this, the more I think that using the context API (for all the stores — page, preloading and session) is the most regret-proof approach, using the proposal above

session can be used to pass data from the server related to the current request. It is a writable store, meaning you can update it with new data. If, for example, you populate the session with the current user on the server, you can update the store when the user logs in. Your components will refresh to reflect the new state

Just realised this doesn't actually work. If store is just something exported by the app, there's no way to prevent leakage. Instead, it needs to be tied to rendering, which means we need to use the context API. Sapper needs to provide a top level component that sets the store as context for the rest of the app. You would therefore only be able to access it during initialisation, which means you couldn't do it inside a setTimeout and get someone else's session by accident:

It's really helpful that Svelte stores are easy to use in plain JS. We can change a state store over completely to Svelte and make the Angular components subscribe to that store as well without needing to maintain and sync 2 copies of the state.

Stores are such an amazing abstraction.

This subscription function must be immediately and synchronously called with the store's current value upon calling .subscribe. All of a store's active subscription functions must later be synchronously called whenever the store's value changes.

Assignments to $-prefixed variables require that the variable be a writable store, and will result in a call to the store's .set method.

Here's a proxy store I wrote to derive the value of a store nested within other stores, it plays nice with typescript and can go infinitely deep

Generally, you should read the value of a store by subscribing to it and using the value as it changes over time. Occasionally, you may need to retrieve the value of a store to which you're not subscribed. get allows you to do so.

Using another reactive statement with $effect we have Svelte automatically handle subscribing and unsubscribing to the store

One thing I considered was abusing a custom store for this kind of thing.

const store = readable(machine.initialState, set => { service.subscribe(state => { if (state.changed) set(state) }) service.start() return () => { service.stop() } })

The readable store takes a function as a second argument which has its own internal set method, allowing us to wrap any api, like Xstate or Redux that has its own built in sub­scrip­tion model but with a slightly different api.

Indeed, this simple contract is very close to that of an ob­serv­able, such as those provided by Rxjs. set is basically equiv­a­lent to next in the ob­serv­able world.

The $ contract for auto-sub­scrib­ing is lovely in its sim­plic­ity and flex­i­bil­ity. You can adapt your own preferred state-man­age­ment pattern or library, with or without Svelte stores as helpers. Svelte does not fuss about how you want to manage your state.

Arguably what is in­ter­est­ing about Svelte’s approach to state man­age­ment is not the store itself but the auto-sub­scrip­tion that is possible because of the Svelte compiler. By simply appending a $ to a variable inside of a component, e.g. $myVariable, the compiler will know to expect an object with a subscribe method on it and generate the boil­er­plate of sub­scrib­ing and un­sub­scrib­ing for you.

setClient(writable(apolloClient)); let client getClient().subscribe((_client) => client = _client);

setContext / getContext can only be used once at component init, so how do you share your API result through context? Related: how would you share those API results if the call was made outside of a Svelte component, where setContext would be even more out of the question (and the API call would arguably be better located, for separation of concerns matters)? Well, put a store in your context.

This is pretty good, but I don’t love that $contactStore.length bit. If we wanted to change the shape of the store from an array to a key-value store or something, we’d have to remember to update this component too. Instead, we can define a new derived store: contactCountStore. It’ll always track the count, which lets this component have less knowledge about the structure of the store. That refactor looks like this:

I used a "specific function". But maybe it could be done within a derived store. A kind of auto reset on ... But I think there is no elagant solution, so I stick with the specific function.

You're not limited to using $count inside the markup, either — you can use it anywhere in the <script> as well, such as in event handlers or reactive declarations.

$: console.log(`the count is ${$count}`);

Stores are global state. While context is local state.

Notice it's not related to components. Another crucial difference is that it's accessible from outside of components. And good way to determine where goes where is to ask yourself, can this particular state and functionality still makes sense outside of the displayed component?

In fact, you might use the two together. Since context is not reactive, values that change over time should be represented as stores:

For interoperability with RxJS Observables, the .subscribe method is also allowed to return an object with an .unsubscribe method, rather than return the unsubscription function directly.

Our understanding of building platforms and sequencing towards them is still nascent. From how to shift the allocation of resources between a company’s core business and its potential future expansions to how to structure a platform to catalyze its growth and more. Until the playbook is well understood, it is more art than science. There are many decisions to make, including which layers should be centralized, whether the ecosystem should be driven by open source contributors or profit-seeking enterprises, how broad in scope to allow the ecosystem to grow and where to not let it grow, and more.

Add-ons hosted on the AMO generally need to have their source code uploaded in an extra (really annoying) manual step.

Issues brought up during review must be addressed using best efforts. If corrections have been requested, the new version should not contain unrelated changes, as this complicates the review process and can lead to further rejections.

During review, the add-on undergoes basic testing in addition to code review. To facilitate the functional testing, the add-on author must provide testing information and, if applicable, testing credentials required to use the add-on if an account is needed for any part of the add-on’s functionality.

You can now distribute your add-on. Note, however, that your add-on may still be subject to further review, if it is you’ll receive notification of the outcome of the review later.

Mozilla can still block distribution of the extension, even when not distributed via ADO. It is not possible for us to provide Mozilla the unminified JavaScript source files for Google’s and Microsoft’s translation widgets. This is a risk because Mozilla can demand such.
