Environment Variables

Configuration lives in .env.local (copy .env.example to start). Variables without a NEXT_PUBLIC_ prefix are server-side only and never reach the browser; NEXT_PUBLIC_ variables are inlined into the client bundle at build time, so only put non-secret values there.

Required

Variable	Description
`SPREE_API_URL`	Your Spree API endpoint (e.g. `http://localhost:3000` in dev, `https://api.mystore.com` in production)
`SPREE_PUBLISHABLE_KEY`	Publishable API key from your Spree admin

<Note> In a Docker build these two are also required at **build time** — the storefront prerenders pages against the Spree API. See [Deployment](/developer/storefront/nextjs/deployment). </Note>

Store defaults

Used by the middleware for initial redirects before API data loads, and as build-time fallbacks for sitemap/SEO generation.

Variable	Description	Default
`NEXT_PUBLIC_DEFAULT_COUNTRY`	Default country ISO code — should match your store's `default_country_iso`	`us`
`NEXT_PUBLIC_DEFAULT_LOCALE`	Default locale code — should match your store's `default_locale`	`en`
`NEXT_PUBLIC_SITE_URL`	Public site URL, used for sitemap and `robots.txt` generation (e.g. `https://mystore.com`)	(required for sitemap)
`NEXT_PUBLIC_STORE_NAME`	Store name used in metadata fallbacks	`Spree Store`
`NEXT_PUBLIC_STORE_DESCRIPTION`	Store description used in metadata fallbacks	(sample text)

Optional overrides for site metadata and the Organization JSON-LD. When unset, values fall back to store settings from the Spree API.

Variable	Description
`STORE_SEO_TITLE`	Default `<title>`
`STORE_META_DESCRIPTION`	Default meta description
`STORE_META_KEYWORDS`	Default meta keywords
`STORE_TWITTER`	Twitter/X handle or URL
`STORE_FACEBOOK`	Facebook page URL
`STORE_INSTAGRAM`	Instagram URL
`STORE_LOGO_URL`	Logo URL for Organization JSON-LD
`STORE_SUPPORT_EMAIL`	Customer support email

Wholesale B2B portal

The wholesale portal is an opt-in addon, off by default.

Variable	Description	Default
`SPREE_WHOLESALE_CHANNEL`	Enable switch — the code of a gated Spree channel to bind the `/wholesale` surface to. Unset means DTC-only: every wholesale entry point is hidden and the routes 404	(disabled)
`SPREE_WHOLESALE_PUBLISHABLE_KEY`	Channel-scoped publishable key for the wholesale surface. Optional — the channel header selects the channel, so this falls back to `SPREE_PUBLISHABLE_KEY`	(falls back to `SPREE_PUBLISHABLE_KEY`)

Transactional emails

See the Transactional Emails guide for the full setup.

Variable	Description	Default
`SPREE_WEBHOOK_SECRET`	Webhook endpoint secret key that signs incoming Spree webhooks	(disabled)
`RESEND_API_KEY`	Resend API key for sending emails in production	(dev: writes to disk)
`EMAIL_FROM`	"From" address for transactional emails (e.g. `Store <[email protected]>`)	`[email protected]`

Payments

Publishable keys for client-side payment SDKs, read when the matching gateway is enabled. Set the key for whichever provider(s) you use.

Variable	Description
`NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY`	Stripe publishable key (`pk_…`)

Analytics

Variable	Description	Default
`GTM_ID`	Google Tag Manager container ID (e.g. `GTM-XXXXXXX`). Leave empty to disable	(disabled)

Error tracking (Sentry)

Variable	Description	Default
`SENTRY_DSN`	Sentry DSN — set to enable error tracking (e.g. `https://[email protected]/0`)	(disabled)
`SENTRY_ORG`	Sentry organization slug (for source map uploads)	(none)
`SENTRY_PROJECT`	Sentry project slug (for source map uploads)	(none)
`SENTRY_AUTH_TOKEN`	Sentry auth token (for source map uploads in CI)	(none)
`SENTRY_SEND_DEFAULT_PII`	Send PII (IP addresses, cookies, user data) to Sentry server-side	`false`
`NEXT_PUBLIC_SENTRY_SEND_DEFAULT_PII`	Send PII to Sentry client-side	`false`

<Warning> PII collection is disabled by default. Only set the `SENTRY_SEND_DEFAULT_PII` variables to `true` if you have appropriate user consent or a privacy policy covering this data. </Warning>
