| 1: | # EJS |
| 2: | |
| 3: | Embedded JavaScript templates. |
| 4: | |
| 5: | ## Installation |
| 6: | |
| 7: | $ npm install ejs |
| 8: | |
| 9: | ## Features |
| 10: | |
| 11: | * Complies with the [Express](http://expressjs.com) view system |
| 12: | * Static caching of intermediate JavaScript |
| 13: | * Unbuffered code for conditionals etc `<% code %>` |
| 14: | * Escapes html by default with `<%= code %>` |
| 15: | * Unescaped buffering with `<%- code %>` |
| 16: | * Supports tag customization |
| 17: | * Filter support for designer-friendly templates |
| 18: | * Client-side support |
| 19: | |
| 20: | ## Example |
| 21: | |
| 22: | <% if (user) { %> |
| 23: | <h2><%= user.name %></h2> |
| 24: | <% } %> |
| 25: | |
| 26: | ## Usage |
| 27: | |
| 28: | ejs.compile(str, options); |
| 29: | // => Function |
| 30: | |
| 31: | ejs.render(str, options); |
| 32: | // => str |
| 33: | |
| 34: | ## Options |
| 35: | |
| 36: | - `locals` Local variables object |
| 37: | - `cache` Compiled functions are cached, requires `filename` |
| 38: | - `filename` Used by `cache` to key caches |
| 39: | - `scope` Function execution context |
| 40: | - `debug` Output generated function body |
| 41: | - `open` Open tag, defaulting to "<%" |
| 42: | - `close` Closing tag, defaulting to "%>" |
| 43: | |
| 44: | ## Custom tags |
| 45: | |
| 46: | Custom tags can also be applied globally: |
| 47: | |
| 48: | var ejs = require('ejs'); |
| 49: | ejs.open = '{{'; |
| 50: | ejs.close = '}}'; |
| 51: | |
| 52: | Which would make the following a valid template: |
| 53: | |
| 54: | <h1>{{= title }}</h1> |
| 55: | |
| 56: | ## Filters |
| 57: | |
| 58: | EJS conditionally supports the concept of "filters". A "filter chain" |
| 59: | is a designer friendly api for manipulating data, without writing JavaScript. |
| 60: | |
| 61: | Filters can be applied by supplying the _:_ modifier, so for example if we wish to take the array `[{ name: 'tj' }, { name: 'mape' }, { name: 'guillermo' }]` and output a list of names we can do this simply with filters: |
| 62: | |
| 63: | Template: |
| 64: | |
| 65: | <p><%=: users | map:'name' | join %></p> |
| 66: | |
| 67: | Output: |
| 68: | |
| 69: | <p>Tj, Mape, Guillermo</p> |
| 70: | |
| 71: | Render call: |
| 72: | |
| 73: | ejs.render(str, { |
| 74: | locals: { |
| 75: | users: [ |
| 76: | { name: 'tj' }, |
| 77: | { name: 'mape' }, |
| 78: | { name: 'guillermo' } |
| 79: | ] |
| 80: | } |
| 81: | }); |
| 82: | |
| 83: | Or perhaps capitalize the first user's name for display: |
| 84: | |
| 85: | <p><%=: users | first | capitalize %></p> |
| 86: | |
| 87: | ## Filter list |
| 88: | |
| 89: | Currently these filters are available: |
| 90: | |
| 91: | - first |
| 92: | - last |
| 93: | - capitalize |
| 94: | - downcase |
| 95: | - upcase |
| 96: | - sort |
| 97: | - sort_by:'prop' |
| 98: | - size |
| 99: | - length |
| 100: | - plus:n |
| 101: | - minus:n |
| 102: | - times:n |
| 103: | - divided_by:n |
| 104: | - join:'val' |
| 105: | - truncate:n |
| 106: | - truncate_words:n |
| 107: | - replace:pattern,substitution |
| 108: | - prepend:val |
| 109: | - append:val |
| 110: | - map:'prop' |
| 111: | - reverse |
| 112: | - get:'prop' |
| 113: | |
| 114: | ## Adding filters |
| 115: | |
| 116: | To add a filter simply add a method to the `.filters` object: |
| 117: | |
| 118: | ```js |
| 119: | ejs.filters.last = function(obj) { |
| 120: | return obj[obj.length - 1]; |
| 121: | }; |
| 122: | ``` |
| 123: | |
| 124: | ## client-side support |
| 125: | |
| 126: | include `./ejs.js` or `./ejs.min.js` and `require("ejs").compile(str)`. |
