html-injector
Usage
node.js
var htmlInjector = require('html-injector);
fs.createReadStream(infile)
.pipe(htmlInjector({
tag: { globs, cwd, transforms }
})
.pipe(fs.createWriteStream(outfile));command-line
$ html-injector infile tag [globs...] > outfilenode.js (multiple injection)
var htmlInjector = require('html-injector);
fs.createReadStream(infile)
.pipe(htmlInjector({
tag1: { globs, cwd, transforms },
tag2: { globs, cwd, transforms }
})
.pipe(fs.createWriteStream(outfile));command-line (multiple injection)
$ html-injector infile tag1 [globs...] | html-injector tag2 [globs...] > outfileHTMLInjector(configuration)
Returns a through stream in which content has been transformed.
All transformations happen between injection tags:
<!--tag-->
<script type="text/ng-template" id="{$path}">
{$content}
</script>
<!--tag-->configuration
Configures how to transform content between each tag pair.
{
[tag]: {
globs,
cwd,
transforms
}
}globs
string[]
One or more node-glob patterns.
If this is specified, content between each pair of tags will be repeated once per matching file.
Two special transforms become available:
$path returns file path
$content returns file content
cwd (optional)
string
Default: process.cwd()
Current working directory for globs. Injected file paths will be relative to this directory.
transforms
{[token: string]: string | Function}
A transform is a function that receives a string as input and returns a transformed string as output.
Bracket content is initially an empty string. Transforms transform bracket content.
As a shorthand, a transform that simply returns a string may be specified as a string.
Transforms are called in the order they appear between brackets. For example, the following bracket will be replaced by the file path which gets passed to firstTransform then secondTransform.
{$path firstTransform secondTransform}
That is, secondTransform(firstTransform($path)).
Transforms can alternatively be specified in a special file called hi.js at the root of the project (see examples). Transforms passed directly to replace() take precedence.
Example 1
Run npm run cli-example.
You should see the expected output below printed to stdout.
Example 2
Run npm run node-example.
You should get a generated index.html file containing the expected output below.
