Lessons learned while demoing API to non-developers

By Arnaud Lauret, November 22, 2019

What would you do if you had to demo API to non-developers in a highly-constrained context? How would you do without curl, Postman or any other API tool usually used? How would you do without your usual fun API examples? I had to do that a few weeks ago and was quite happy by the questions that arose and the solutions found. The whole story definitely deserves a post in order to share what I’ve learned!


API Design Tips And Tricks - What if consumers can't do PATCH, PUT or DELETE?

By Arnaud Lauret, November 7, 2019

There are quite many APIs out there taking advantage of all standard HTTP methods (GET, POST, PATCH, PUT and DELETE). Unfortunately, there are still some cases where consumers can’t use them all. As far as I know, GET and POST do not cause any problem at all. But as an API provider, do not take for granted that DELETE, PUT and the more dreaded PATCH HTTP methods can always be used by your consumers. I encountered this problem several times throughout the years and no later than a few weeks ago. Let’s see why and how to solve this problem.


Few things I learned writing The Design of Web APIs

By Arnaud Lauret, November 2, 2019

At last, my book The Design of Web APIs is finished and printed! I gradually got back to a “normal” life since the end of summer as the book entered in its production phase, but it was only when I received the printed copies two weeks ago that I had the feeling that this adventure was really over. And then holding the book in my hands, I wondered if it was worth having spent two years of my life on it, what did I learn spending almost all my free time working on this book? That sounded like a good topic to revive the API Handyman blog.

How public web APIs raise software bar

By Arnaud Lauret, February 26, 2018

While answering some question on my Design of Web APIs book’s forum, I wrote:

Now that I have seen brilliant Web APIs that can be used so easily because of their design but also the overall experience some can provide (the famous “DX”) I have become far more demanding and challenging with software in general

Yes. Public web APIs definitely raise software bar. The whole software industry should take example on them …

...And GraphQL for all?

By Arnaud Lauret, September 29, 2017
GraphQL is new. GraphQL is cool. Look! Github dumped REST for it! We MUST do it too! Well, why not. GraphQL could be a great tool, but like any tool, you don't choose it "just because".You choose it because it solves a problem in a given context. You choose it knowing its strengths and weaknesses. During this session, while discovering what is GraphQL we will see what REST API providers should think about before blindly dumping REST for it
