Pinned 2026 toolchains (Go 1.26, Rust 1.98/edition 2024, Python 3.14 + uv, Node 24, Zig 0.16, NixOS 26.05), postgres 18 / mongo 8, lockfiles built from, non-root runtimes, .dockerignore, per-project LICENSE, READMEs with the git.devai.io clone line, checkout@v7 CI. Security fixes in the legacy Rust APIs (any-password login, self-assigned admin, hard-coded JWT secret), JWT alg/exp/sub enforcement across the blog series, safe markdown links in the frontends, and many smaller bugs — every project was built, run and exercised end to end. Adds scripts/publish.sh + a CI publish job that splits every folder into its own repo at git.devai.io/templates/<folder>.

# todo-list
|
|
|
|
A real to-do app that remembers your tasks after a refresh — built from one
|
|
array, one `render()` function and `localStorage`. It teaches the idea every
|
|
framework is built on: the data is the truth, and the screen is redrawn from it.
|
|
|
|
## Run
|
|
|
|
Get it: `git clone https://git.devai.io/templates/todo-list.git`
|
|
|
|
Double-click `index.html` — it opens in your browser and works. Nothing to
|
|
install, no build step.
|
|
|
|
Or serve it like production:
|
|
|
|
```sh
|
|
docker compose up --build
|
|
```
|
|
|
|
Then open http://localhost:8080.
|
|
|
|
## How it works
|
|
|
|
All the tasks live in one array, `tasks`, of `{ text, done }` objects. Every
|
|
action — add, tick, delete — follows the same three steps:
|
|
|
|
1. change the array (`push`, flip `done`, or `filter` a task out),
|
|
2. `save()` it to `localStorage` (as JSON, because it only stores text),
|
|
3. `render()` — clear the list and rebuild every `<li>` from the array.
|
|
|
|
Because the screen is always rebuilt from the data, the two can never drift
|
|
apart. On load, the array is read back with `JSON.parse`, so your list is still
|
|
there after a refresh.
|
|
|
|
Try it: add a "Clear completed" button (`tasks.filter((t) => !t.done)`), put
|
|
new tasks on top with `unshift` instead of `push`, or stamp each task with
|
|
`new Date().toLocaleDateString()`.
|
|
|
|
## Layout
|
|
|
|
```
|
|
index.html the form, an empty <ul>, and the "left" counter
|
|
app.js the tasks array, save() and render()
|
|
styles.css the look; follows your system's light or dark mode
|
|
```
|
|
|
|
## Deploy
|
|
|
|
Push to your own GitHub repo and the shipped workflow
|
|
(`.github/workflows/ci.yml`) tests the compose stack, publishes the image to
|
|
GHCR, and — once you set the `DEPLOY_HOST` / `DEPLOY_USER` variables and
|
|
`DEPLOY_KEY` secret — deploys it to your server over ssh.
