use stderr instead console.log

It would be nice to avoid writing to console.log for debugging messages. Since MCP is using stdio, those messages generate errors in the protocols.

dotenv/lib/main.js

Line 93 in 59d9e87

console.log(`[dotenv@${version}][INFO] ${message}`)

Yeah this is a good point.

Have you seen dotenvx? It does this correctly.

Can you also speak to MCP more? Are you using dotenv as an MCP server somehow?

I will take a look at dotenvx.

I have a node.js application that runs as an MCP. When using the stdio transport, any console.log output will be interpreted in the MCP transports which leads to some warnings about incorrect messages.

i'm removing _log in the upcoming release. dotenv will just have _debug if debug: true is set.

meanwhile, dotenvx will support more controlled log levels:
