@open-tech-world/parse-env-file

Node.js utility to parse .env files.

Note: Apart from .env files, you can pass any valid file with any extension to get parsed. Eg: .env.staging, env.txt, etc.

Syntax rules

• It expects each line in a file to be in VAR=VAL format.
• Lines beginning with # are processed as comments and ignored.
• Blank lines are ignored.
• The quotation marks in VAL will not be stripped away.

Input with mixed valid & invalid lines:

# Comment 1
ENV=val

# ENV1=val1

// Comment 2
ENV2=val2

// ENV_VAR=Some Value

ENV3= val3

ENV4 =val4

ENV5 = val5

ENV6=Lorem Ipsum is simply dummy \n text of the printing and typesetting industry.

NEW_ENV_VAR_6=10

NEW_ENV_VAR_7=https://example.com

NODE_PATH=/usr/local/lib/node_modules:/home/runner/node_modules

EMPTY=

JSON={"foo": "bar"}

FOO=" some value "

FLAG=true

Output:

{
      ENV: 'val',
      ENV2: 'val2',
      '// ENV_VAR': 'Some Value',
      ENV3: 'val3',
      ENV4: 'val4',
      ENV5: 'val5',
      ENV6: `Lorem Ipsum is simply dummy \n text of the printing and typesetting industry.`,
      NEW_ENV_VAR_6: '10',
      NEW_ENV_VAR_7: 'https://example.com',
      NODE_PATH: '/usr/local/lib/node_modules:/home/runner/node_modules',
      EMPTY: '',
      JSON: '{"foo": "bar"}',
      FOO: '" some value "',
      FLAG: 'true',
}
