This is a blog entry that I wrote before I change my blog, most of it may be old and probably outdated.
When i start working on this blog (based in ghost), i put a bunch of sensitive data in environment variables in the heroku configuration.
The problem was a key of google drive API, the content is a multi-line string and can’t make it work in one line. When i put the new line character into the string \n, it wasn’t interpreted by node.
The only solution that i found for this problem was this, convert the string to a buffer and then to string again.
| // set the TEST environment variable with TEST=first line\\n\\nsecond line\\n | |
| // you need to duplicate the \ to scape it | |
| function parseEnvVarible(envVar){ | |
| return new Buffer(envVar.split('\\n').join(require('os').EOL), 'UTF-8').toString('UTF-8'); | |
| } | |
| console.log('Wrong: ' + process.env.TEST); | |
| console.log('Right: ' + parseEnvVarible(process.env.TEST)); |
