# Overview
|
|
|
|
In the AIO application, we offer the reader the option to download each example as a full self-contained
|
|
runnable project packaged as a zip file. These zip files are generated by the utility in this folder.
|
|
|
|
## Example zipper
|
|
|
|
The `exampleZipper.js` tool is very similar to the Stackblitz's `builder.js`. The latter creates an HTML file
|
|
with all the examples' files and the former creates a zip file instead. They both use the `stackblitz.json` file
|
|
to flag an example as something to stackblitz or zip. For example:
|
|
|
|
```json
|
|
{
|
|
"description": "Tour of Heroes: Part 6",
|
|
"files":[
|
|
"!**/*.d.ts",
|
|
"!**/*.js",
|
|
"!**/*.[1,2].*"
|
|
],
|
|
"tags": ["tutorial", "tour", "heroes", "http"]
|
|
}
|
|
```
|
|
|
|
The zipper will use this information for creating new zips.
|
|
|
|
## Two kinds of examples
|
|
|
|
There are mainly two kinds of AIO docs examples: The ones based on the Angular CLI and the ones based on SystemJS.
|
|
The majority of the examples are CLI-based with only some of the `ngUpgrade` examples using SystemJS.
|
|
|
|
Some of the CLI-based examples require small tweaks to the default layout/configuration (for example, to add support for Angular elements, i18n, universal, etc.).
|
|
These example types have separate boilerplate directories with the files that are different from the default `cli` boilerplate.
|
|
|
|
There are appropriate `package.json` files for each type of example in the boilerplate directories.
|
|
If there is no special `package.json` file for an example type, the one from the `cli` boilerplate directory will be used instead.
|
|
|
|
The `exampleZipper.js` won't include any `System.js` related files for CLI-based projects.
|
|
|
|
## The zipper.json
|
|
|
|
As mentioned, the tool uses the `stackblitz.json` as a flag and also a configuration file for the zipper.
|
|
The problem is that not all examples have a stackblitz but they could offer a zip instead.
|
|
|
|
In those cases, you can create a `zipper.json` file with the same syntax. It will be ignored by the
|
|
stackblitz tool.
|
|
|
|
## Executing the zip generation
|
|
|
|
`generateZips.js` will create a zip for each `stackblitz.json` or `zipper.json` it finds.
|
|
|
|
Where? At `src/generated/zips/`.
|
|
|
|
Then the `<live-example>` embedded component will look at this folder to get the zip it needs for
|
|
the example.
