Your next MirrorS is not MirrorS, nor MirrorSes, it's MirrorZ.

A final site for Mirror sites.

Demo and

Also legacy webpages (for w3m and noscript users) are provided in and

A speed test script is also provided. See README for more info.


Mirror sites are heterogeneous. It is hard for a single mirror to provide all mirrors, so differences occur.

For end users, this is not a good experience as they need to search for available mirrors.

To make things easy, MirrorZ is intended to include all mirrorS, so a unified interface is needed.

Data Format v1.7

A mirrorz.json in the following format describes all the data of one mirror site in MirrorZ.

Developing and Contributing

Repo organization

This repo depends on other repos in this organization to provide full functionality; However, they are not submodules as we need to bump submodules whenever there is an update, which is painful. We just use the latest version of each repo when building.

For full preparation of all the repos, you should refer to the Prepare steps in Github Actions.

Note that yarn mirrorz_env prepares for When you are debugging, it is recommended to use yarn dev_env and yarn debug_build, which builds the site for http://localhost:1234. Other env like cngi_env and cernet_env prepares for other sites that mirrorz maintain.



One may use

yarn --frozen-lockfile
yarn start

to start a local server. It is often convenient for debugging frontend features like html/css since auto-reload is provided by parcel.

Parser, local new static files

To debug one src/parser with new site json in static/json/site, use

yarn --frozen-lockfile
yarn half_start

to start a local server. Python3 is required in this case. Note there is no auto-reload feature.

Legacy pages

To use static files, 404 redirection (emulate Github pages) and legacy pages, one may use

yarn --frozen-lockfile
yarn full_start

to start a local server. Python3 is required in this case. Note there is no auto-reload feature.


For dynamic web page part, only

yarn build

is required.

However if one also wants to deploy the static web page, one may use

yarn build
yarn legacy_build

Note that legacy_build has dependencies on files yarn build has made.

Meanwhile, to generate the complete, one should use the following command

yarn ohmymirrorz_build

If one want all parts, one can use the following command to accomplish all the steps above

yarn full_build


Currently *.json is ignored in .gitignore (not ignored in /static). If one wants to commit a json file, they should use git add -f.
