Always uses default value

[bayerlse]

Hello There,

I have following example:

export const config = convict<ConfigSchema>({
    env: {
        doc: 'The application environment.',
        default: ENV.LIVE, // === "production"
        format: ['production', 'development', 'test'],
        env: 'NODE_ENV'
    },
    dbKeyFile: {
        doc: 'Database key file path',
        format: String,
        default: '.tmp/keyfile.json',
        env: 'DB_KEY_FILE'
    }
});

When I run my code with webpack mode --development (which sets NODE_ENV) and do:

console.log(config.get('env'))
it returns always the default value: "production"

console.log(process.env.NODE_ENV)
it return the correct value: "development"

What is wrong here? Shouldnt get convict the value from process.env?

Thanks!

The problem is actually that webpack is setting process.env.NODE_ENV=development and not setting the actual NODE_ENV environment variable to development.

Here was my workaround:

Sorry, I misremembered. That code solves a similar but different problem.

Experiencing the same issue on 6.1.0, but without webpack. No matter what I set the corresponding env var, it always uses the default value:

// config.js
const config = convict({
  env: {
    doc: 'The application environment.',
    format: ['production', 'development', 'test'],
    default: 'development',
    env: 'NODE_ENV'
  },
  host: {
    doc: 'Listen host for server',
    format: '*',
    default: '127.0.0.1',
    env: 'HOST'
  },
  port: {
    doc: 'Listen port for server',
    format: 'port',
    default: 3000,
    env: 'PORT'
  }
})
module.exports = config

// server.js
const config = require('./config.js')
const hostAtShell = process.env.HOST // this value is correct
const host = config.get('db.host') // Always returns the default 127.0.0.1
console.log(hostAtShell === host) // false

@Silur Facing the same issue. Did you solve it?

[Silur]

no, I removed convict from my setup and use process.env.MY_CONF_VAR || 'default value' instead

[AlexZeitler]

Looks like my issue has been different. It didn't notice process.env.MY_CONF_VAR='some-value' but it did work when I set the environment variables when starting the process or using this in my config.ts file and using a .env file:

import { config as loadEnv } from 'dotenv'
loadEnv()

Totally agree with you, I removed it now.

import { config as loadEnv } from 'dotenv'
loadEnv({ path: 'PATH_TO_ENV_FILE' })
