Hurl is a very interesting project that extends the functionality of curl
.
It offers an alternative to more GUI oriented software like Postman.
Hurl is foremost a command line tool and should be easy to use on a local
computer, or in a CI/CD pipeline. Some tools in the same space as Hurl
(Postman for instance), are GUI oriented, and we find it less attractive than
CLI
-- Hurl FAQ
This caught my attention. I've been a user of Postman for a while, but over time
I've found the tool to be more and more clunky, especially when working on
larger projects.
- It's awkward to navigate.
- It can be slow and memory hungry, especially when there are lots of tabs open.
- It's written with the mouse in mind, keyboard shortcuts feel more like an afterthought.
- It's hard, or at least awkward, to integrate into other tools.
All of these problems have been resolved for me by combining Neovim and Hurl.
To do this I wrote a plugin, nvim-hurl.nvim,
it runs hurl files and displays the response those files get from the server.
Using this setup I was able to solve all the issues I had with Postman
leveraging the power of Neovim and Hurl together.
- Jumping around files with a fuzzy finder like Telescope or fzf is a lot more comfortable. I don't waste time scrolling through tabs or searching through giant collections anymore.
- This will depend on the plugins you use, but for the most part Neovim is a lot lighter Postman. More importantly, I don't find myself in the situation where I have 1000 tabs open anymore. This is a user problem to some extent, I could always just close tabs, but Postman's design really encourages it.
- Using Vim keybindings means I automatically get a more keyboard centered workflow.
- Once I'm done editing the Hurl files, I can run them however I want. It was easy to integrate into Neovim, it's easy to integrate it into a CLI, and it would be easy to integrate it into anything that can run command line tools.
This setup also let me take advantage of the entire neovim plugin ecosystem.
- I get highlighting from Treesitter. There's already support for hurl files, and by setting the file type of the response we get highlighting there as well.
- If there's an LSP running, it can be used on the response. There's no support Hurl files yet, but it's convenient when you need to format json responses for example.
- I've already mentioned it, but fuzzy finding in Neovim is great.
The plugin also offers additional features for hurl, like being able to swap in
and out variable files with
Hurlsvf {variables_file}
.
This lets you change URL like in the demonstration above, but could also be used
to quickly and easily change OAuth tokens for example.
It also offers a way to interactively explore APIs with a command named
CurlGoFromCursor
. It runs a simple curl command from your cursor allowing you
to quickly navigate through links in RESTful APIs.
Because the Hurl file is just text, and the response is just text,
it’s very easy to add functionality to the plugin and very easy to
integrate into an existing workflow. Hurl might not have all the features
of some of its GUI competitors at the moment, but it doesn't need those
features if it's so easy to integrate it into other tools that have those
features.
