Reasons that we love it: - -* No runtime libraries. No magic. Just simple pre-compilation to a clear code -* Super easy to write panels. By panels we mean components that have a lot of HTML code and non-reusable logic -* Very good separation of presentation and logic. Almost no HTML within the component file -* Declerative coding for presentation. HTML that you write and inspect look similar -* Easy syntax. Similar to HTML. All IDEs recognize this format - -## How does it work -React templates compiles a *.rt file (react template file - extended HTML format) into a javascript file. Currently, this file supports requirejs format, that will return a function. This function, when applied, will return a virtual react DOM (based on React.DOM elements and user custom components). A common use case would be that a React component would require a JS file generated by a template, and then call `func.apply(this)`, causing the template to have the component as its context. - -###### Basic concepts for react templates -* Any valid HTML is a template (and comments) -* {} to identify JS expression -* rt-if -* rt-repeat -* rt-scope -* rt-class -* style -* event handlers -* doctype rt, require dependencies, and calling other components - -###### Why not use JSX? -Some love jsx, some don't. We don't. Well, not that we don't like it, but it seems to fit only components with very little html inside, which could be done by creating elements in code. Also, we like to separate code and html. It just feels right. - -## Usage -**src/cli.js < filename.rt >** -*(you might need to provide execution permission to the file)* - -Note that in most cases, this package will be wrapped in a grunt task, so the cli will not be used directly -TODO: pointer to the grunt repository - -# Template directives and syntax - -## Any valid HTML is a template -Writing any html is a valid template. This does not apply to event handlers ("on" methods). See the section about event handlers - -## {} to identify JS expression -In html attributes and text, you can replace context by a javascript expression. You do this by wrapping it in {}. If this is inside an attribute, it still needs to be wrapped by quotes. In text, you can just use it. - -###### Sample: -```html -{this.state.linkText} -``` -###### Compiled: -```javascript -define([ - 'react', - 'lodash' -], function (React, _) { - 'use strict'; - return function () { - return React.DOM.a({ 'href': this.state.linkRef }, this.state.linkText); - }; -}); -``` -*Note: within the special **"rt-"** directives, simple strings don't make sense, as all those directives apply on some execution context. Therefore, in these directives, there won't be a need to add the {} to identify execution context* - -## rt-if -This gives you the ability to add conditions to a sub-tree of html. If the condition is evaluated to true, the subree will be returned, otherwise, it will not be calculated. It is implemented by a trinary expression - - -###### Sample: -```html -
Success!
-``` -###### Compiled: -```javascript -define([ - 'react', - 'lodash' -], function (React, _) { - 'use strict'; - return function () { - return this.state.resultCode === 200 ? React.DOM.div({}, 'Success!') : null; - }; -}); -``` - -## rt-repeat -Repeats a node with its subtree for each item in an array. This is implemented by creating a method that is passed to a map call as a callback. It creates a real context for the iterated variable. The syntax is `rt-repeat="itemVar in arrayExpr"`. Within the scope of the element, `itemVar` will be available in javascript context, and also an `itemVarIndex` will be created to represent the index of the item. If the definition is `myNum in this.getMyNumbers()`, than there will be 2 variables in the scope: `myNum` and `myNumIndex`. This naming is used to allow nesting of repeat expression with access to all levels. - -###### Sample: -```html -
{myNumIndex}. myNum
-``` -###### Compiled: -```javascript -define([ - 'react', - 'lodash' -], function (React, _) { - 'use strict'; - function repeatMyNum1(myNum, myNumIndex) { - return React.DOM.div({}, myNumIndex + '. myNum'); - } - return function () { - return _.map(this.getMyNumbers(), repeatMyNum1.bind(this)); - }; -}); -``` - -## rt-scope -This directive creates a new javascript scope. It actually creates a new method for this scope, and calls it with its current context. The syntax is `rt-scope="expr1 as var1; expr2 as var2`. This gives a convenience method to shorten stuff up in a scope and make the code more readable. It also helps to execute an expression only once in a scope instead of every chunk that needs it. - -###### Sample: -```html -
-
{rptIndex}{separator} {val}
-
'rpt' exists here, but not 'separator' and 'val'
-
-``` -###### Compiled: -```javascript -define([ - 'react', - 'lodash' -], function (React, _) { - 'use strict'; - function scopeSeparatorVal1(rpt, rptIndex, separator, val) { - return React.DOM.div({}, rptIndex + separator + ' ' + val); - } - function repeatRpt2(rpt, rptIndex) { - return React.DOM.div({}, scopeSeparatorVal1.apply(this, [ - rpt, - rptIndex, - ')', - rpt.val - ]), React.DOM.div({}, '\'rpt\' exists here, but not \'separator\' and \'val\'')); - } - return function () { - return _.map(array, repeatRpt2.bind(this)); - }; -}); -``` - -## rt-class -In order to reduce the boiler-plate code when programatically setting class names, you can use the rt-class directive. It expectes to get a JSON object with keys as class names, and a value of true or false as the value. If the value is true, the class name will be included. Please note the following: -1. In react templates, you can use the "class" attribute the same as you'd do in html. If you like, you can even have execution context within -2. You cannot use class and rt-class on the same html element - -###### Sample: -```html -
- These are logically equivalent -
Reference
-
Inline
-
Using the class attribute
-
-``` -###### Compiled: -```javascript -define([ - 'react', - 'lodash' -], function (React, _) { - 'use strict'; - function scopeClasses1(classes) { - return React.DOM.div({}, 'These are logically equivalent', React.DOM.div({ 'className': React.addons.classSet(classes) }, 'Reference'), React.DOM.div({ - 'className': React.addons.classSet({ - blue: true, - selected: this.isSelected() - }) - }, 'Inline'), React.DOM.div({ 'className': 'blue' + this.isSelected() ? ' selected' : '' }, 'Using the class attribute')); - } - return function () { - return scopeClasses1.apply(this, [{ - blue: true, - selected: this.isSelected() - }]); - }; -}); -``` - -## style -In order to make it closer to html, we allow the settings of inline styles. In addition, this will take care of changing the styles from hyphen-style to camelCase style. If you'd like, you can still return an object from evaluation context. Please note that if you do it inline, you'll need to open single curly braces for the js context, and another for the object. Also, you'll need to use camelCase if using it that way - -###### Sample: -```html -
- These are really equivalent -
Inline
-
Inline
-
-``` -###### Compiled: -```javascript -define([ - 'react', - 'lodash' -], function (React, _) { - 'use strict'; - return function () { - return React.DOM.div({}, 'These are really equivalent', React.DOM.div({ - 'style': { - color: 'white', - lineHeight: this.state.lineHeight + 'px' - } - }, 'Inline'), React.DOM.div({ - 'style': { - 'color': 'white', - 'lineHeight': this.state.lineHeight + 'px' - } - }, 'Inline')); - }; -}); -``` - -## event handlers -React event handlers accept function pointers. Therefore, when using event, you can just open an execution context and provide a pointer to a method. This would look like `onClick="{this.myClickHandler}"`. However, sometimes there's very little to do on click, or we just want to call a method with bound parameters. In that case, you can use a lambda notation, which will result in creating a react template creating a method for the handler. It does not have a performance impact, as the method is created once, and just bound to the context instead of created again. The lambda notation will look like this `onClick="(evt) => console.log(evt)"`. In this example, **evt** was the name you choose for the first argument that will be passed into your inline method. With browser events, this will most likely be the react synthetic event. However, if you expect a property that starts with **on**Something, then react-templates will treat it as an event handler. So if you have an event handler called **onBoxSelected** that will trigger an event with a row and column params, you can write `onBoxSelected="(row, col)=>this.doSomething(row,col)"`. You can use a no-param version as well `onClick="()=>console.log('just wanted to know it clicked')"` - -###### Sample: -```html -
-
-
-``` -###### Compiled: -```javascript -define([ - 'react', - 'lodash' -], function (React, _) { - 'use strict'; - function onClick1(item, itemIndex) { - this.itemSelected(item); - } - function repeatItem2(item, itemIndex) { - return React.DOM.div({}, React.DOM.div({ - 'onClick': onClick1.bind(this, item, itemIndex), - 'onMouseDown': this.mouseDownHandler - })); - } - return function () { - return _.map(items, repeatItem2.bind(this)); - }; -}); -``` - -## doctype rt, require dependencies, and calling other components -In many cases, you'd like to use either library code, or other components within your template. In order to do so, you can define a doctype and indicate dependencies. You do so by ``. After that, you will have **depVarName** in your scope. You can import react components and use them afterwords in the template as tag names. For example ``. This will also support nesting `
child
another
`. You will then be able to find the children in **this.props.children**. - -###### Sample: -```html - - -
{utils.toLower(item.name)}
- - -``` -###### Compiled: -```javascript -define([ - 'react', - 'lodash', - 'comps/myComp', - 'utils/utils' -], function (React, _, MyComp, utils) { - 'use strict'; - function repeatItem1(item, itemIndex) { - return MyComp({}, React.DOM.div({}, utils.toLower(item.name))); - } - return function () { - return _.map(items, repeatItem1.bind(this)); - }; -}); -``` +Moved to gh-pages branch. diff --git a/index.html b/index.html deleted file mode 100644 index 857138d..0000000 --- a/index.html +++ /dev/null @@ -1,16 +0,0 @@ - - - - - React templates - Image Search Sample - - - - - -

Sometimes it's called a "filter", -// but that's not a great name for it, since that implies a thing where -// some bits pass through, and others are simply ignored. (That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform.
