This is a starting point for Go solutions to the
|
|
||||||
["Build Your Own HTTP server" Challenge](https://app.codecrafters.io/courses/http-server/overview).
|
|
||||||
|
|
||||||
[HTTP](https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol) is the
|
|
||||||
protocol that powers the web. In this challenge, you'll build a HTTP/1.1 server
|
|
||||||
that is capable of serving multiple clients.
|
|
||||||
|
|
||||||
Along the way you'll learn about TCP servers,
|
|
||||||
[HTTP request syntax](https://www.w3.org/Protocols/rfc2616/rfc2616-sec5.html),
|
|
||||||
and more.

||||||

|
||||||
# Passing the first stage
|
|
||||||
|
|
||||||
The entry point for your HTTP server implementation is in `app/server.go`. Study
|
|
||||||
and uncomment the relevant code, and push your changes to pass the first stage:
|
|
||||||
|
|
||||||
```sh
|
|
||||||
git commit -am "pass 1st stage" # any msg
|
|
||||||
git push origin master
|
|
||||||
```
|
|
||||||
|
|
||||||
Time to move on to the next stage!

# Stage 2 & beyond
|
|
||||||
|
|
||||||
Note: This section is for stages 2 and beyond.
|
|
||||||
|
|
||||||
1. Ensure you have `go (1.19)` installed locally
|
|
||||||
1. Run `./your_program.sh` to run your program, which is implemented in
|
|
||||||
`app/server.go`.
|
|
||||||
1. Commit your changes and run `git push origin master` to submit your solution
|
|
||||||
to CodeCrafters. Test output will be streamed to your terminal.

["Build Your Own SQLite" Challenge](https://codecrafters.io/challenges/sqlite).
|
|
||||||
|
|

In this challenge, you'll build a barebones SQLite implementation that supports
|
|
||||||
basic SQL queries like `SELECT`. Along the way we'll learn about
|
|
||||||
[SQLite's file format](https://www.sqlite.org/fileformat.html), how indexed data
|
|
||||||
is
|
|
||||||
[stored in B-trees](https://jvns.ca/blog/2014/10/02/how-does-sqlite-work-part-2-btrees/)

|
|
||||||
|
|
||||||

# Stage 2 & beyond
|
|
||||||
|
|
||||||
Note: This section is for stages 2 and beyond.
|
|
||||||
|
|
||||||
1. Ensure you have `go (1.16+)` installed locally
|
|
||||||
1. Run `./your_program.sh` to run your program, which is implemented in
|
|
||||||
`app/main.go`.
|
|
||||||
1. Commit your changes and run `git push origin master` to submit your solution
|
|
||||||
to CodeCrafters. Test output will be streamed to your terminal.
|
|
||||||
|
|
||||||
# Sample Databases
|
|
||||||
|
|
||||||
To make it easy to test queries locally, we've added a sample database in the
|
|
||||||
root of this repository: `sample.db`.
|
|
||||||
|
|
||||||
This contains two tables: `apples` & `oranges`. You can use this to test your
|
|
||||||
implementation for the first 6 stages.
|
|
||||||
|
|
||||||
You can explore this database by running queries against it like this:
|
|
||||||
|
|
||||||
```sh
|
|
||||||
$ sqlite3 sample.db "select id, name from apples"
|
|
||||||
1|Granny Smith
|
|
||||||
2|Fuji
|
|
||||||
3|Honeycrisp
|
|
||||||
4|Golden Delicious
|
|
||||||
```
|
|
||||||
|
|
||||||
There are two other databases that you can use:
|
|
||||||
|
|
||||||
1. `superheroes.db`:
|
|
||||||
- This is a small version of the test database used in the table-scan stage.
|
|
||||||
- It contains one table: `superheroes`.
|
|
||||||
- It is ~1MB in size.
|
|
||||||
1. `companies.db`:
|
|
||||||
- This is a small version of the test database used in the index-scan stage.
|
|
||||||
- It contains one table: `companies`, and one index: `idx_companies_country`
|
|
||||||
- It is ~7MB in size.
|
|
||||||
|
|
||||||
These aren't included in the repository because they're large in size. You can
|
|
||||||
download them by running this script:
|
|
||||||
|
|
||||||
```sh
|
|
||||||
./download_sample_databases.sh
|
|
||||||
```
|
|
||||||
|
|
||||||
If the script doesn't work for some reason, you can download the databases
|
|
||||||
directly from
|
|
||||||
[codecrafters-io/sample-sqlite-databases](https://github.com/codecrafters-io/sample-sqlite-databases).
