<h2>v5.0.0</h2>
<h2>v5 Release</h2>
<p><code>v5</code> of the Codecov GitHub Action will use the <a
href="https://github.com/codecov/wrapper">Codecov Wrapper</a> to
encapsulate the <a
href="https://github.com/codecov/codecov-cli">CLI</a>. This will help
ensure that the Action gets updates quicker.</p>
<h3>Migration Guide</h3>

for tokens for public repositories. In the <code>Global Upload
Token</code> section of the settings page of an organization in

reports from any source. This will allow contributors or other members
of a repository to upload without needing access to the Codecov token.

to upload without a token</a>.</p>

Test with Go 1.24 (#244)

Set slice capacity based on input in `Map` and `Classes.Render` (#243)

Hey! I just discovered this repo and I love being able to write
templates while still having compile-time checks.

I was looking through the code and noticed slices aren't currently
preallocated in `Map()` and `Classes.Render()`. Preallocating will
improve performance since the resulting slice won't have to be grown
dynamically during the append loop.

Add 'download' and 'referrerpolicy' attributes for anchor <a> element (#242)

Hello,

A patch to add
[`download`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a#download)
and
[`referrerpolicy`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a#referrerpolicy)
for the anchor `<a>` element.

Add formxxx attributes (for <input type="submit"> element) (#241)

Hello,

A small patch to add the following attributes:

- formaction
- formenctype
- formmethod
- formnovalidate
- formtarget

These attributes are useful in `<input type="submit">` element: [MDN
documentation](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/submit#additional_attributes)

Add support for additional HTML attributes in HTML5 template (#238)

This PR updates the HTML5 function to accept and render additional HTML
attributes. An additional test case to validate this enhancement has
been added as well.

Add web component elements and slot attribute (#235)

The slot attribute is a standard attribute for use with web components:
https://developer.mozilla.org/en-US/docs/Web/API/Web_components/Using_templates_and_slots

Add gomponents-starter-kit link to readme

Release v1 (#226)

v1.0.0-beta1 gave no problems with my other gomponents libraries, that
of others, and some of my large projects, so releasing v1!

No more breaking changes! 😁

Add test for dot imports (#225)

So we can be sure all dot imports work at the same time.

Add missing 'hidden' attribute (#224)

Upgrade CI workflow (#223)

Mainly the linter action is easier to use.

Add version to go get command in readme

Until we're out of beta.

Fix attr panic test (#222)

It didn't actually work the way it was written.

Remove mention of SVG package in doc comments

Fix example app to use maragu.dev/gomponents module path (#216)

Move module to maragu.dev/gomponents namespace (#215)

This is a breaking change to move gomponents to my own import namespace.

I will obviously be careful with this, test it out in all kinds of
scenarios, release betas, etc. But otherwise, because the `Node`
interface is so simple and has basically never changed, I don't think
this will break much. 🤞

Fixes #200

Remove SVG package (#214)

Because the added value of having this was very small, and I don't want
to confuse people about what's properly supported, I've removed the SVG
package. As #196 showed, there can easily be conflicts between HTML and
SVG, and the rendering isn't really set up for anything else than HTML.

It's still easy to create SVG elements: `html.SVG` exists in this repo,
and the rest is often just a string that can be included using `g.Raw`.

Fixes #206

Fix `mailto:` in FUNDING.yml not working

Add invoicing contact option to readme

Add ExampleMap_index

For getting the slice index using a counter outside the closure.

Fix links in package documentation

Apparently, [Node]s doesn't link in Godoc, while [Node]-s does.

Use go workspace in example app (#211)

Fix doc comments regarding `Group`

Make `Group` a type (#202)

This changes `Group` to be a type instead of a function, which means it
can support both grouping `[]Node` as well as doing variadic-ish slice things
like `Group{n1, n2}`.

This also means that `Map` can just return a `Group`.

Special thanks to @deitrix for this simple and elegant solution that,
for some reason or another, has had me perplexed for a long time.

Fixes #201.

Revert "Add Github Pages website deployment workflow (#207)"

This reverts commit a4327a0fb6bd02a3d8fb7677ba118b3b5dd1b3e8.

Add Github Pages website deployment workflow (#207)

Remove redundant sentence from readme

Reword readme slightly

Add full example app (#204)

Also, remove the other examples and simplify the readme.

Drop support for Go 1.16 and Go 1.17 (#203)

Fixes #184

Make Groups renderable (#181)

This change makes the result of `Group` renderable directly, instead of
panicking, with the important caveat that root-level attributes are
_ignored_. I don't think this will give problems in practice, as the
main use case for rendering `Group` is basically to return root-level
elements to the client using something like HTMX.

I tried adding a `Fragment`, but it was weird and confusing having two
functions (`Group` and `Fragment`) do essentially the same thing, the
only difference being whether the argument was a slice of `Node`s or
varargs.

Fixes #162

Reduce code duplication by reusing the correct function in deprecated functions (#194)

Fix `cite` name clash example in readme

Add `cite` attribute (#192)

It can appear in a `<blockquote>`.

Test on Go 1.23 in CI (#193)

Add draggable attribute (#185)

Add links to godoc (#183)

Also add an example for `http.Adapt`.

Fixes #182

Add LabelEl (#180)

For consistency with the other name clashes. Also, adjust the readme.

I know it's a bit weird to add a pre-deprecated function, but know it's
the same as the other functions.

Adjust documentation on Iff (#179)

Add datetime attribute (#177)

`<time>`, `<del>` and `<ins>` can receive a
[`datetime`](https://developer.mozilla.org/en-US/docs/Web/API/HTMLTimeElement/dateTime)
attribute

Add an `Iff` helper (#172)

I ran into some situation where I want to conditionally render a node if
some variable is not nil and obviously I got a panic

```go
// package viewmodels
type SomePage struct {
	s *string
}

// package views
func SomePage (vm viewmodels.SomePage) g,Node {
	return Div(
		If(vm.s == nil, Text("s is nil"),
		If(vm.s !- nil, Text("s is " + vm.s), // this will panic when `s` is nil
	)
}
```

In this situation, go will interpret the code of the second `if`
regardless of the condition because the code itself is not in a
condition.

This PR introduces a new `Iff` helper that accepts a callback. The
callback content is only interpreted when it's called, making the code
safe:

```go
// package viewmodels
type SomePage struct {
	s *string
}

// package views
func SomePage (vm viewmodels.SomePage) g,Node {
	return Div(
		Iff(vm.s == nil, func () g.Node { return Text("s is nil") },
		Iff(vm.s !- nil, func () g.Node { return Text("s is " + vm.s) },
	)
}
```

I'm aware of the `Lazy` effort on the side, but I guess this is no a
breaking change and can still exist in addition to the `Lazy` effort.

Add dir (#176)

`dir` is a global attribute that lets you specify whether text is RTL or
LTR or if it should be determined by the browser.

Add LabelAttr and List attributes (#175)

Fixes #168 and fixes #169.

Deprecate DataAttr, StyleAttr, TitleAttr, FormEl (#174)

This change addresses #170 by deprecating some HTML helpers in favor of
using one of the styles as a main one, selected based on what I think is
the main use case.

- For `Data`, it's the attribute. I don't see much use of the `<data>`
element in the wild.
- For `Style`, it's the attribute. The `style` attribute is everywhere,
the `<style>` element is perhaps less so (but not much). This was the
hardest one to decide.
- For `Title`, it's the attribute. The `<title>` element only shows up
once per document.
- For `Form`, it's the element. I haven't seen much use of the `form`
attribute in the wild.

I know this is arguably not a "consistent" approach, but I think it
makes for a much nicer API, simply because the most-used option will not
be a suffixed version.

Add script's `integrity` and `crossorigin` attributes (#173)

When using `<script>` to pull a library from a CDN, it's usually a good
idea to attach an integrity check so that if they get hacked and someone
changes all the script, malicious scripts don't get executed on your
website.

To achieve this, you need to attach `integrity` and `crossorigin` to
your `<script/>` tag

```go
Script(
	Scr("https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta1/dist/js/bootstrap.bundle.min.js"),
	Integrity("sha384-ygbV9kiqUc6oa4msXn9868pTtWMgiQaeYH7/t7LECLbyPA2x65Kgf80OJFdroafW"),
	CrossOrigin("anonymous"),
)
```
Turns into
```html
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta1/dist/js/bootstrap.bundle.min.js" 
    integrity="sha384-ygbV9kiqUc6oa4msXn9868pTtWMgiQaeYH7/t7LECLbyPA2x65Kgf80OJFdroafW" 
    crossorigin="anonymous"></script>
```

Hint for whoever likes unpkg.com, adding `?meta` at the end of any
script you import form them will give you the current `integrity` for
the file. Example: https://unpkg.com/three@0.165.0/build/three.cjs?meta

Revert "Add Marquee element promotion to readme"

Add Go report card to readme (#111)

Also fix godoc badge to point to pkg.go.dev.

Fix small typo occured -> occurred (#110)

Add EncType html attribute (#109)

Add generic Map implementation (#108)

Instead of waiting for a good time to switch the `Map` implementation,
I've decided to just offer two implementations: one for Go versions
before 1.18, and one for 1.18 and onwards. This is achieved using build
tags in the source files.

This is obviously a breaking change for consumers of this library that
use Go 1.18 and onwards.

See #88

Add Go 1.19 to test matrix (#107)

Use output of strings.Builder in assert.Equal (#106)

Make void elements a map (#103)

Update CI config (#98)

- Drop current test workflows if a new one has come in

Test using Go 1.17 (#91)

Also set the new `-shuffle` flag when testing.

Escape Attr values (#77)

Because this can be a place of injection if untrusted data is passed, escape all attribute values.

Fixes #74.

Fix TailwindCSS CDN URL in example (#76)

The CSS style URLs from unpkg.com redirected to a different page, but the first request set a `Content-Type` header of `text/plain`. Using the direct URLs fixes this.

Fixes #75. Thanks to @gedw99 for reporting.

Update readme with content from website (#73)

Add svg package and a few helpers (#67)

Introducing SVG, to inline vector graphics in your HTML! 🥳

Fix code in readme (#69)

Broken in #66.

Update license year (#68)

Streamline HTML element API (#66)

There were a lot of elements previously, like `Em`, `H1`, and a lot more, that took a string as the first argument previously. This was weird when you wanted to mix elements to output html like `<strong><em>…</em></strong>` or `<h1>Something <em>something</em> something</h1>`. gomponents is not an HTML validator, so I want people to be able to use elements however they please, also without text content.

This also means that all elements now have the same API.

Use g.If in HTML5 helper (#65)

Inlining looks much nicer.

Return Node from all helpers instead of NodeFunc (#62)

This makes it clearer that the helpers return a `Node` of any kind, and that the type is not important.

This also streamlines the API, as attribute helpers already return just `Node`.

Add data- attribute helper (#61)

Fixes #49.

Add test for InputHidden (#60)

Add aria-* and role attributes (#59)

Fixes #50.

Add If helper function (#57)

Used to inline conditional nodes.

Change main example to be the dot-import version (#56)

Simplify available elements (#55)

`a`, `form`, `img`, `input`, `label`, `option`, `progress`, `select`, and `textarea` are now just regular elements (without helper parameters), because:
- Sometimes the use case doesn't fit (`a` as anchor without href, for example)
- There's no reason these are special among the others, so streamlining them makes sense

Also added new attributes `action`, `alt`, `for`, `method` that I had somehow missed.

Rename Document to Doctype (#54)

Move elements and attributes into html package (#52)

This makes it easier to use dot-imports.

Also updated the readme and examples with new usage, and move the `Classes` helper into the `components` package.

Minor refactoring and comment changes (#51)

Add example with dot imports (#47)

Add svg element (#46)

Also add `cols` and `rows` attributes.

Fixes #43.

Add NodeType which replaces the Placer interface (#45)

The `Placer` interface was a weird interface that tried to abstract away nodes being elements or attributes, but it doesn't really make sense. Now `Nodes` just have a `NodeType`.

Render correct HTML5 (#44)

Previously, elements of kind void and empty elements generally would be rendered auto-closing (with a final `/` character in the start tag), which is allowed sometimes but arguably wrong. See https://dev.w3.org/html5/spec-LC/syntax.html#end-tags

This created problems with for example `textarea` and `script`, which cannot be auto-closing, or the browser renders it wrong.

Also clarified in the docs that this library outputs HTML5.

Fixes #42.

Add package docs (#41)

Also update readme with features.

Add Map function (#40)

`Map` makes it easier to build lists of elements without having to iterate.

Render to Writer instead of string (#39)

The Render function has been changed to take a `Writer` instead of returning a string. This makes it possible to generate documents without having the whole content in memory.

This also removes the `gomponents.Write` function, which is now redundant.

Furthermore, the `el.Document` function has been changed to only take one child, as multiple children never make sense for it. (It's not even a child, more a sibling.)

Remove fmt.Sprintf call in attribute Render (#38)

Just concatenating the strings is much faster.

Add convenience helpers for form elements (#19)

Introduce Placer interface (#18)

When implemented, the `Place` method of the `Placer` interface tells `Render` in `El` where to put a Node. This is relevant for helpers that want to be rendered like attributes, inside the parent element.

Fixes the bug where `attr.Classes` was rendered outside the element.

Add Textf function (#17)

Like Text, but calls fmt.Sprintf before rendering.

Add better example in readme (#16)

Add children varargs to h1-6, b, strong, i, em, img helpers (#15)

This makes it possible to add attributes.

Make attr.Classes a map type (#14)

This makes the usage syntax prettier. Instead of `attr.Classes(map[string]bool{})`, we can just use `attr.Classes{}`.

Add simple example (#13)

Add a test for attr.String (#12)

Add a Write function (#11)

Add a lot of common elements (#10)

Especially add elements that are either used in every document, that nearly always have text content, or that are almost always used with certain attributes.
