Module
github.com/neresson/sveda-go-sdk.
No Gin or Echo required.
go get github.com/neresson/sveda-go-sdkgo get github.com/neresson/sveda-go-sdk
3. Env
SVEDA_CLIENT_BASE_URL=http://127.0.0.1:8787
SVEDA_CLIENT_HOST_API_KEY=replace-meSVEDA_CLIENT_BASE_URL=http://127.0.0.1:8787 SVEDA_CLIENT_HOST_API_KEY=replace-me
4. POST /sveda/session
sveda.StartHostSession
returns a struct tagged
origin,
token,
expires_in,
appearance.
Empty env returns an error — map that to 503.
Optional
policy
on the mint maps your app role to a named capability set —
embed policies.

}) 5. Templates
Only emit
data-sveda-*,
chat buttons, and
sveda-host.js
when
SvedaOrigin
is non-empty.
