dotenv loads your .env — it doesn't check it. So I built a typed validator.

A PORT=8O80 typo (that's a letter O), a DATABASE_URL you forgot to set, a NODE_ENV=prodd — none of these fail when your app starts. They fail later: a cryptic stack trace three layers into startup, a service that boots but talks to the wrong database, a feature flag that's silently off in production. The error is never "your env is wrong"; it's whatever broke downstream.

dotenv loads your .env. It doesn't check it. So I built envward: validate the whole environment against a small typed schema up front, and fail loudly — with the actual problem — before a single line of app code runs. Zero dependencies, no network.

$ envward

.env — checked against env.schema.json

3 problem(s), 3 key(s) valid
