Svelte Commerce × X-Cart

Svelte Commerce on X-Cart

Solid core coverage: cart, checkout and sign-in are wired against X-Cart’s modern API, and the one recorded gap is vendors. Every call carries the store’s API key; a shopper’s token joins it after sign-in.

What works on X-Cart today

Cart, checkout and sign-in are wired; vendors are the one recorded gap. Cart and checkout need X-Cart’s read/write API key, and the connector takes it from a PUBLIC_ variable, which the browser receives.

Cart

Wired: issues a real request to X-Cart.

Checkout

Wired: issues a real request to X-Cart.

Sign-in (auth)

Wired: issues a real request to X-Cart.

Known gaps: vendor — each is explained under Limitations below.

26 of 43 services wired, read from CONNECTORS.md on , where the package version is recorded too; npm may carry a newer patch. Coverage is traced by a script in the Svelte Commerce repository: a service counts as wired only if it transitively issues an HTTP request, or delegates to one that does. It is not hand-asserted. Some services are Litekart-native concepts with no equivalent elsewhere (reels, deals, chat, gallery, popularity, demo-request, feedback, plugins, banner). They stay documented placeholders on every connector and are excluded from known gaps.

Quick start

From nothing to a Svelte Commerce storefront reading X-Cart. You need Node.js and a X-Cart to point it at; the storefront holds no data of its own.

Clone it, choose the connector, point it at X-Cart

# 1 — get the storefront
git clone https://github.com/itswadesh/svelte-commerce
cd svelte-commerce

# 2 — one connector at a time: remove the two the storefront ships with, add this one
npm uninstall @misiki/litekart-connector @misiki/vendure-connector
npm i @misiki/x-cart-connector

# 3 — point it at your X-Cart store
echo PUBLIC_X_CART_API_URL=https://your-store.example.com >> .env
echo PUBLIC_X_CART_API_KEY=... >> .env

# 4 — run it
npm run dev

The guide removes only @misiki/litekart-connector. A fresh clone’s package.json also lists @misiki/vendure-connector, and with two connectors installed and neither of them Litekart’s, the build stops and asks for PUBLIC_CONNECTOR — so this removes both.

Environment variables

What Svelte Commerce reads to reach X-Cart
VariableRequiredWhat it does
PUBLIC_X_CART_API_URLYesYour X-Cart store’s URL. Boot fails, naming this variable, if it is missing.
PUBLIC_X_CART_API_KEYNoThe store API key from X-Cart’s Settings › API, sent as X-Auth-Token on every call. A read-only key rejects writes, so cart and checkout need the read/write key. See the limitations.
PUBLIC_X_CART_ACCESS_TOKENNoSent as a bearer token when set; a shopper’s token after sign-in travels the same way.
PUBLIC_CONNECTORNoOnly when more than one connector is installed: @misiki/x-cart-connector names the one this build runs on.

init.ts hands the connector every PUBLIC_X_CART_* variable that is set, camel-cased. The guide also lists PUBLIC_X_CART_API_SECRET, PUBLIC_X_CART_ACCESS_KEY, PUBLIC_X_CART_STORE_ID and PUBLIC_X_CART_CHANNEL_ID; the connector’s source does not read them.

Every variable here begins PUBLIC_, and SvelteKit sends PUBLIC_ variables to the browser: treat each value you set as published.

What to set up on X-Cart

How the integration works

X-Cart 5.5.1 and later want two headers: X-Auth-Token, the store API key, on every call, and Authorization: Bearer, the shopper’s token, once they have signed in. A read-only key is enough to browse but rejects every POST, PATCH and DELETE.

Installing the package is the whole switch. vite.config.ts resolves whichever @misiki/*-connector is installed, and src/lib/core/connectors/init.ts hands it every PUBLIC_X_CART_* variable that is set, camel-cased, at boot — in the server hook for server rendering and in the client hook for the browser, which must reach the same URL in production.

There is no Litekart API behind the storefront here, so store identity — name, logo, currency, menus, plugin toggles, theme colours — comes from src/lib/core/connectors/default-store.json merged under the default export of kitcommerce.config.ts. Until you override it, the store is called “Test”. Any Litekart REST path the connector still inherits is answered from that local data, or resolved empty, rather than requested.

Limitations

Troubleshooting

Errors you may meet running Svelte Commerce on X-Cart, and what fixes them
When you seeWhat to do
Boot fails with “the x-cart connector is active but PUBLIC_X_CART_API_URL is not set”Add PUBLIC_X_CART_API_URL to .env. A production Node build and Docker read PUBLIC_* from the process environment rather than .env, so set it on your deploy platform too.
The build stops with “Several commerce connectors are installed … Set PUBLIC_CONNECTOR to pick one”More than one @misiki/*-connector is in package.json and none is Litekart’s. Uninstall the ones you do not run — a fresh clone also lists @misiki/vendure-connector — or set PUBLIC_CONNECTOR='@misiki/x-cart-connector'.
Boot fails with “PUBLIC_…_API_URL is set, but it configures a different backend than the one this build runs on”Another backend’s variable is still set, usually left over from the one you switched from. Remove it, or install that backend’s connector. PUBLIC_LITEKART_API_URL is exempt: it only points the dev proxy.
The store is called “Test”, or shows the wrong name and logoStore identity is static on this backend. Set name, logo, currencyCode and the rest in the default export of kitcommerce.config.ts; src/lib/core/connectors/default-store.json lists every field.
[x-cart] no native implementation for get /api/... in the consoleThe connector’s REST guard caught a path inherited from Litekart and answered it empty instead of requesting it. Each path is reported once. Harmless if X-Cart has no such feature; if it has one, the fix belongs in the connector’s matching service.
http proxy error: api/... ECONNREFUSED in devA Litekart REST path was requested from outside the connector, so its guard never saw it. Vite proxies /api to PUBLIC_LITEKART_API_URL, or to localhost:7000.
The build fails on @misiki/litekart-connector@misiki/kitcommerce-core declares it as a peer, and vite.config.ts redirects that specifier to whichever connector is installed. Make sure exactly one @misiki/*-connector is listed in package.json.

Before you rely on it

The one caveat that matters

Read this before choosing

Every connector was written by reading its platform’s authoritative source — an OpenAPI spec, a RAML file, a router registration or the controller source — rather than by running against a store. No connector has been exercised against a live production instance of its platform.

FAQ

Questions about Svelte Commerce on X-Cart

Can I run an X-Cart store on Svelte Commerce today?

Cart, checkout and sign-in are wired, and vendors are the only recorded gap. The obstacle is the key: cart and checkout need X-Cart’s read/write API key, which the connector reads from a PUBLIC_ variable that every visitor’s browser receives.

How do I switch Svelte Commerce to X-Cart?

Remove the connectors the storefront ships with, install @misiki/x-cart-connector, set PUBLIC_X_CART_API_URL in .env and start the dev server. vite.config.ts resolves whichever connector is installed, so no file in the storefront changes.

Which X-Cart versions and keys does the connector need?

X-Cart 5.5.1 or later, and the read/write store API key from Settings › API, sent as X-Auth-Token. A read-only key can browse but rejects cart and checkout writes.

Has the X-Cart connector been run against a real X-Cart store?

Not against a live production instance — no Svelte Commerce connector has been. It was written by reading X-Cart’s authoritative API source, and the Svelte Commerce maintainers ask X-Cart’s own maintainers for a sandbox to run it against.
