bun-v0.0.71
版本发布时间: 2022-02-25 21:49:39
oven-sh/bun最新发布版本:bun-v1.1.38(2024-11-29 19:55:48)
To upgrade:
bun upgrade
Having trouble?
# Try this
curl https://bun.sh/install | bash
Please let me know though if it doesn't work and you're on bun v0.0.69. bun v0.0.61 - v0.0.68 had issues with the HTTP client
Highlights:
- More reliable
bun install: numerous bug fixes to linking, serialization, deserialization, extracting files. It probably works in many projects now. There are still a couple bugs that need to be fixed, no node-gyp yet, andgit/githubdependencies don't work yet - "Copy as markdown" for error messages
- Macros can now be used like regular JavaScript, with automatic conversion of primitives & objects to Bun's AST
-
bun pm hashreturns a hash of the resolved all package@version in your lockfile -
bun install --globallets you globally install npm packages with bun! - bug fixes to bun dev & bun run
-
TextEncoder,TextDecoder,process.exit,crypto.randomUUID,crypto.randomBytesare now available in bun.js - Better support for Next.js v12.1
# Install a package globally with bun install
> bun install -g typescript
# "bun i" is shorthand for bun install
> bun i -g typescript
# It symlinks into your $BUN_INSTALL/bin folder
> which tsc
/Users/jarred/.bun/bin/tsc
# print the path of the global bin
> bun pm -g bin
/Users/jarred/.bun/bin
Lowlights:
- Breaking changes to
bun installlockfile format change means your nextbun installwill invalidate existing ones. The changes improve the reliability of saving and loading the lockfile
"Copy as markdown" button for error messages
Before this release, bun dev did not support displaying runtime errors. It only showed errors for build/ssr 🙈
Use macros like regular JavaScript
Now you can move code from runtime to build-time by writing ordinary javascript.
Input:
// This line is removed at build time
import {weatherIn} from 'macro:./weather'
// This function call is replaced with the value of `weatherIn(94609)` at build-time
const {current_condition: [{temp_F: degrees}]} = weatherIn(94609);
export default `It is ${degrees} in Oakland, California`
weather.js:
export async function weatherIn(call) {
const location = call.arguments[0];
return fetch(`https://wttr.in/${location.toString()}?format=j1`)
}
Output:
const {
current_condition: [{ temp_F: degrees }]
} = {
current_condition: [
{
temp_F: "42"
}
]
};
// once bun gets a minifier, this line would be all that remains
export default `It is ${degrees} in Oakland, California`;
Normally, this 48 KB of JSON would be fetched client-side

JavaScript Parser reliability
I ported some of esbuild's tests to bun's testing library and that led to uncovering & fixing some parser bugs
// what some of the tests look like
expectParseError("-x.y() ** 2", "Unexpected **");
expectParseError("+x.y() ** 2", "Unexpected **");
expectParseError("~x.y() ** 2", "Unexpected **");
expectParseError("!x.y() ** 2", "Unexpected **");
expectParseError("void x.y() ** 2", "Unexpected **");
expectParseError("delete x.y() ** 2", "Unexpected **");
expectParseError("typeof x.y() ** 2", "Unexpected **");
New features
type inside of import clauses is now supported. This is a TypeScript feature.
// previously, this would error
import {type FooType} from 'bar';
Import assertions are now parsed by bun. Currently, they're removed from the final output
import("./foo.json", { type: "json" });
// ⬇️
import("./foo.json");
import json from "./foo.json" assert { type: "json" };
// ⬇️
import json from "./foo.json";
Fixed a number of whitespace/formatting bugs with the printer
bun install reliability
This release brings bun install much closer to something you can use daily. It's not there yet, but it is close.
Somewhat controversially, bun install uses a binary lockfile format. One thing several people asked for: a hash. So I added a hash.
> bun pm hash
1A0FF3DFFE05333A-b20fd0e1259d2de5-9E3B657EA8BD4436-9f3132e0eb95a60e
This is a SHA512/256 hash of the following string. The string is created by looping through all the resolved packages in the lockfile, sorting alphabetically, then sorting any packages with multiple duplicate versions.
> bun pm hash-string
-- BEGIN SHA512/256(`${alphabetize(name)}@${order(version)}`) --
@types/node@16.11.26
@types/puppeteer@5.4.5
camel-case@4.1.2
capital-case@1.0.4
change-case@4.1.2
constant-case@3.0.4
dot-case@3.0.4
header-case@2.0.4
js-tokens@4.0.0
loose-envify@1.4.0
lower-case@2.0.2
no-case@3.0.4
object-assign@4.1.1
param-case@3.0.4
pascal-case@3.1.2
path-case@3.0.4
peechy@0.4.24
prettier@2.5.1
react@17.0.2
sentence-case@3.0.4
snake-case@3.0.4
tslib@2.3.1
upper-case@2.0.2
upper-case-first@2.0.2
-- END HASH--
bun pm is a new subcommand for "miscellaneous package manager things"
> bun pm
bun pm - package manager related commands
bun pm bin print the path to bin folder
bun pm -g bin print the global path to bin folder
bun pm hash generate & print the hash of the current lockfile
bun pm hash-string print the string used to hash the lockfile
bun pm hash-print print the hash stored in the current lockfile
When using bun install -y, the hash is inserted into the saved yarn.lock:
# THIS IS AN AUTOGENERATED FILE. DO NOT EDIT THIS FILE DIRECTLY.
# yarn lockfile v1
# bun ./bun.lockb --hash: 3982DAEC20B10CF8-4da4f73e6f1d3ab1-77B62BB40B50C631-a7674fe7d3217550
You can now configure bun install with bunfig.toml. it will search for bunfig.toml in $XDG_CONFIG_HOME/bunfig.toml and $HOME/bunfig.toml, in addition to ./bunfig.toml

Upgraded to the latest version of JavaScriptCore/WebKit, enabling
ShadowRealmsupport -
Fast
TextEncoderandTextDecoderimplementation -
process.exit(exitCode)is now implemented -
crypto.randomUUIDandcrypto.randomBytes() -
setTimeout,setInterval,clearTimeout,clearIntervalare stubbed in to bun.js. They do not actually work yet, but at least code that calls it won't error anymore
Other
try running bun wiptest in a project that uses jest
it'll probably throw a not implemented error, but it might work
