  • Mike Perham of Sidekiq: “If you build something valuable, charge money for it.”

    EmailEngine has all the code public [1], even though it is not open-source but is source-available. Some core parts I even published under the MIT license, like the IMAP client library I built from scratch to serve the special requirements EmailEngine has for IMAP access [2]

    My thinking has always been that those who try to hack the license validation stuff and replace the missing build pipeline were never going to be my customers in the first place, so every second I would spend on them is a wasted effort.

    Oh, yeah, I forgot my pitch. The link is - EnailEngine acts as a mail client, basically the same way Thunderbird runs on desktop, or the iPhone Mail on phone, but instead of a GUI it has REST API and instead of desktop notifications it sends JSON webhooks. And instead of a single email account, it can manage thousands of accounts.

    Well, I for one, hope that email stays as complicated as described in the post. Otherwise my project that simplifies access to email accounts ( would get no traction :D
  • Why is the JavaScript ecosystem like this
    6 projects | | 4 Jan 2023
    I had the same issues when I started with - just like Ghost, it’s an app written in Nodejs. I tried multiple distribution options at first and finally went with complete self containment. All modules are pre-installed during the publishing step and thus the user never needs to run npm. Or if you download the “compiled” single binary version you don’t even need node as it’s bundled with the binary (I use the pkg module to bundle these executables). So upgrading is just downloading and replacing the old version files with new ones.

    The dowside - no sane way to use compiled dependencies, everything has to be vanilla javascript.

  • Do you use Swagger/OpenAPI to document your APIs? If so, what is your preferred way to generate the docs?
    12 projects | /r/node | 30 May 2022
    For I generate swagger docs with the hapi-swagger plugin - the process is pretty much fully automatic as it uses the input and output schema validations.
  • redis vs. ioredis?
    2 projects | /r/node | 26 May 2022
    I use ioredis in and it works very well. Haven’t used the redis module for a long time so can’t compare but I like easily I can set up error retries etc with ioredis. I’ve also used it with Redis Sentinel.
  • Making Open Source economy more viable with dual license collectives
    3 projects | | 10 Jan 2022
    I use a similar model for EmailEngine ( The code is dual-licensed under AGPL and a commercial license. The app has limited functionality by default - you can either buy a license key to activate it and use the app under the commercial license. Or fork the code, remove limitations (really easy to do, one or two lines of changes), and use it as AGPL. At first, I did not have that artificial limitation and no one was interested in buying the commercial license. Once I added that extra step, I got some customers.
  • Selling my own GPL software, part 1: a lot of hurdles
    5 projects | | 25 Dec 2021
    I’m selling an AGPL licensed app that allows to access IMAP/SMTP accounts over REST ( At first I sold it in a way where AGPL version was completely free and public, but you could pay to get the same thing with a MIT-license. Turned out that no-one cared about the license, everyone was happy to use the free AGPL thing, so I changed it in a way where the app is dual licensed under AGPL and proprietary license and you need a “license key” to fully unlock it. As it’s AGPL with source code available from Github you can freely remove that license key check, just a 1-line change. It’s still a big enough of a hurdle that I’ve actually gotten some customers.
